INSTALLATION AND CONNECTION
The Peavey CS-1000 Commercial Series Power Amplifier is designed for durability in commercial installations and the quality of
performance required in studio and home applications. The C5-1000 is a dual-channel power amplifier capable of delivering more than 450
watts RMS per channel into a 4 chm load continuously (both channels). The unit is of the standard 19" rack mount configuration requiring 7"
rack height and is cooled by an automatic two-speed internal fan. All inputs and outputs are on the back panel. The front panel contains
various LED indicators for power output level, DDT activation and thermal shutdown, detented/calibrated sensitivity controls and a
heavy-duty mains power switch.
Mains Power Source
The C5-1000 is fitted with a single heavy-duty #14 AWG, three-conductor line cord and a conventional AC plug with a ground pin. lt should
be connected to a circuit capable of supporting at least 15 amps continuously or greater. This is particularly critical for sustained high power
applications. If the socket used does not have a ground pin, a suitable ground lift adaptor should be used and the third wire grounded
properly. Never break off the ground pin on the C5-1000. The use of an extension cord should be avoided, but if necessary, always use a
three-wire type with at least a#14 AWG wire size. The use of a lighter wire will severely limit the power capability of this amplifier. Always use
a qualified electrician to install any necessary electrical equipment. To prevent the risk of shock or fire hazard, always check to see that the
amp is properly grounded.
Industrial and Commercial Installations
For commercial and other installations where sustained high power operation is required, the amplifiers should be mounted in a standard
19" rack. lt is not necessary to leave rack space between each amplifier in the stack since the fan pulls air in from the rear and exhausts the hot
airout the front. An adequate cool air supply must be provided for the amplifiers when rack mounted. The internal fan must have a source of
air that is not preheated by other equipment. The amplifier will start up in low speed fan operation and will normally stay at low speed
operation unless sustained high power operating levels were to occur. Then as the amplifier heat sinks heat up, the automatic thermal
sensing circuitry will cause high speed operation to occur. Depending upon signal conditions and amp loading, high speed fan operation
may continue or it may cycle continuously between high and low. This situation is quite normal. If cooling is inadequate due to preheated air
ora reduction of air flow occurs due to blockage of the amplifier inlet/outlet ports or if the amplifier is severely overloaded or short-circuited,
then the amplifier thermal sensing system may cause temporary shutdown of that particular channel. This is indicated by the illumination of
the front panel high temperature LED. Depending upon available cooling air, operation should be restored in that channel relatively quickly.
In any event, corrective action should be taken to determine the cause of the thermal shutdown. If the amplifier is not severely overloaded or
shorted and air flow is normal in and out of the amplifier, then steps should be taken to provide a cooler environment for all the amplifiers. Asa
general rule, the cooler electronic equipment is operated, the longer its useful service life. You have invested in the finest equipment that
money can buy, and a little care will insure long and reliable operation.
Portable Rack Mount Applications
Due to the weight of the CS-1000, we highly recommend that additonal support be provided at the back panel of the amplifier whenever one
or more units are installed in a portable rack mount configuration. For this purpose, two %-20 allen head bolts have been provided atthe rear
of the CS5-1000. These bolts should be attached to a suitable bracketing arrangement to provide this additional support. Also, two guards
have been provided on the rear panel of the C5-1200 to protect connectors, PL cans, and provide a means for routing cables. CAUTION:
These are not handles and they should not be used to lift the unit.
Studio and Home Installation
In most low to medium power applications, the power amplifier can be mounted in any configuration. It is desirable that, if at all possible,
the power amplifier be located at the top of an equipment stack. This will prevent possible overheating of sensitive equipment by the hot air
rising from the power amplifier. As a general rule, most home and studio requirements will never cause high speed fan operation. If it does,
however, this may indicate that you have not taken the necessary steps to provide adequate cooling. Remember - closed up in a cabinet, the
C5-1000 will have severe cooling problems, even at low power levels. Again, inadvertent short circuit or sustained overload usage could also
cause temporary thermal shutdown.
Input Connections
All input connections are made at the rear panel. The two '4” jacks marked Power Amp Input (15) are wired in parallel for ease of
connecting to each channel. The dual (parallel) jacks allow daisy-chaining to additional channels. If RCA-type pin jacks are required, a
suitable adaptor can be used. Shielded cables must be used to minimize hum and noise pickup. The nominal input impedance 15 20K ohms.
This impedance represents a bridging load to the associated driving equipment and is compatible with the load requirements of most home
stereo devices. The CS-1000 has an input sensitivity of 1.4V RMS (+3 dBV) for rated output with the front panel sensitivity control set at full
clockwise, again allowing complete compatibility in home applications. This sensitivity rating increases as the control is turned counter-
clockwise. The new sensitivity rating is indicated by the setting of the calibrated sensitivity control. It is generally wise to operate the
sensitivity control at its full clockwise setting. The sensitivity control is discussed in greater detail later in this manual.
Output Connections
Two types of output connectors are provided on the rear panel of the amplifier. Two standard '4” phone jacks wired in parallel (17) andone
set of 5-way binding posts (18) are available from each channel. Due to the high currents at full output it is recommended that #16 AWG or
larger wire size be used whenever possible. Forextremely long runs (30" or greater), #14 AWG should be used. Smaller wire sizes will waste
power and yield less than optimum results at the speaker. It is suggested that in commercial and other non-portable applications, the 5-way
binding posts (18) be used instead of the 4" phone jacks. The binding posts are industry standard and mating banana plugs are available at
most electronic distributors. As with any electronic equipment, proper phase of the outputs is a necessity. A little time spent correctly
identifying the wiring can save a lot of problems in the field. The C5-1000 has a continuous rating of 500 watts EMS into 4 ohms. Music power
operation into 2 ohms should be considered normal and generally will not present any problems. However, continuous operation under
these conditions might cause thermal shutdown, depending upon cooling air temperature. Operating into loads below 2 ohms, although safe
because of electronic protection mechanisms, should be avoided.
OPERATION
The C5-1000 commercial series power amplifier is designed for maximum ease and flexibility of operation. When the unit is installed and
connected as described in the previous sections, operation is as simple as turning on the mains switch (5) and turning up the sensitivity
controls (1) to full clockwise setting, and then adjusting the associated mixer or preamplification equipment to supply the necessary signal
levels to provide the desired output level or until the front panel DDT active LED indicator shows that the amplifier is compressing. Further
increases in signal levels beyond this point will not produce any significant increase in output and could cause distortion problems.
FRONT PANEL
INPUT SENSITIVITY CONTROLS (1)
The CS-1000 employs a 31 detented, calibrated sensitivity control for each channel. These controls are labeled in a more functional
manner, replacing the conventional 0 to 10 segmented circle with the actual input sensitivity ratings of the amplifier for various settings of
this control. In the past, this control has often confused even the most experienced audio technician as to its purpose and usage, especially
when it is simply called level (rather than sensitivity). This new labeling/calibrating technique will help to explain the need and function of
these controls and the significance of the sensitivity rating. We offer the following in way of explanation: The input sensitivity rating of a
power amplifier is the RMS voltage level required at the input to produce full rated power into the rated load at the output. This voltage then
becomes the level at which the associated mixer must operate in order to drive the amplifier to full output. Operation at levels above this
rating will cause the power amplifier to clip (produce distortion) unless the associated amplifier has a compressor or limiter to minimize this
distortion. Such a system, called DDT™ (U.S. Patent #4,318,053), is included in CS-1000 power amplifiers, and the advantages should be
obvious. Without DDT, the sound engineer must “ride gain” on the mixer or employ outboard compressor/limiter, in order to prevent power
amp clipping.
Traditionally, the input sensitivity rating of a power amplifier receives low billing on a typical specification sheet. Often it gets lost among
other interesting specs, such as damping factor, slew rate, transient intermodulation distortion and others. This rating, however, must be
known to have performance visibility at the mixer. Further, the rated sensitivity on the spec sheet is only correct when the power amplifier
sensitivity control is set at full clockwise or maximum setting. Any other setting increases the value. With a numbered circle from 0to 10, this
new higher value is not indicated. Thus, the CS-1000 sensitivity control is calibrated in dBV values (usually listed in typical mixer specs). The
dBV values are useful, since most contemporary mixers employ LED arrays to indicate mixer output levels and are calibrated in dBV.
Knowing the power amplifier sensitivity rating in dBV will allow the mixer operator to know the status of the power amplifier (whether they are
clipping/compressing or not) by noting which LED on the mixer is peaking. Obviously, the LED labeled the same or closest to the sensitivity
rating of the power amplifier will indicate full power output of the system. Operation below that level will indicate how much so called power
amplifier headroom is left. Operation above that level will cause clipping (or compression if the DDT system is operational). Perhaps an
example will be helpful: Referring to the CS-1000 face plate, you will notice that at full clockwise setting of the sensitivity control, the
sensitivity rating is +3 dBV. The critical LED on the driving mixer then is the one labeled +3 dBV. It will correlate with the CS-1000 DDT active
LED in that whenever the +3 dBV LED on the mixer flashes on peaks, the DDT active LED will also flash indicating full power output is
achieved.lf the CS-1000 sensitivity control was adjusted to a higher value, this new value would become the new correlation level on the
associated mixer. There is a very simple rule regarding the setting of the sensitivity (or level) control:
“Unless there is a specific reason not to, the sensitivity control on any power amplifier should be set to full clockwise
position, resulting in the minimum sensitivity rating.”
There are several valid exceptions to the full clockwise rule. The first one presented here involves large systems where it is often necessary
to employ many power amplifiers to supply the same signal to multiple speaker systems to achieve the necessary sound pressure levels or
audience coverage. If the various power amplifiers have different sensitivity ratings and/or the various loudspeaker enclosures have different
efficient ratings, then it might be necessary to adjust certain sensitivity controls to achieve a balanced sound pressure level between the parts
of the system. In this case, the loudest amplifier/speaker combinations will require those amplifier sensitivity controls to be adjusted
counter-clockwise as nesessary. Often in such systems, both Peavey and non-Peavey power amplifiers might be employed. Inthis case, asa
starting point, it might be necessary to match the sensitivity rating of the Peavey power amplifier to that of the competitive power amplifier. As
an example, several competitive power amplifiers on the market have a sensitivity rating of 2 volts RMS (that's +6 dBV as read from the
CS-1000 sensitivity control clock). If such a competitive amplifier is used with the CS-1000, then the C5-1000 must be set to +6 dBV. A second
valid exception to the rule might occur whenever a biamp system is used. This exception will be discussed later in this manual when biamped
systems are presented. A third valid exception is involved in small club, church and studio applications, where the full power output
capability of the power amplifier is not needed or there is no requirement for large amounts of headroom capability. Simultaneously, these
applications usually require a very low noise system. In this case, it is possible to reduce the overall system noise at the expense of headroom
capability by increasing the power amplifier sensitivity accordingly. As an example, if instead of a sensitivity rating of +3 dBV, we adjust the
CS-1000 to a rating of +10 dBV, overall system noise will improved by 7 dB with the resulting 7 dB decrease in system headroom. Remember,
once this is done, the mixer operator cannot reestablish full headroom performance settings at the mixer. If he wants this headroom back, he
must do it by resetting the power amplifier sensitivity.

LED ARRAYS (2)
The CS-1000 has a tricolored LED array on each channel to indicate output power level. The array is calibrated in two different ways to
offer maximum flexibility as to usage. In the center of the LED ladder, the calibration is percent of full power output. The top LED, labeled
100%, will flash when the CS-1000 has reached full RMS power output (500 watts RMS) on that respective channel. Operation at power
output levels below 100% will naturally be indicated by lower LED readings. The lowest value indicated is 0.4% of full power, which
corresponds to 2.0 watts RMS output. Operation below that power level will not be indicated since the lowest LED is calibrated at 0% or
standby. This LED should be illuminated whenever the amplifier is operating with AC mains power applied under zero signal conditions.
Next to each ladder the calibration is “dB below full power.” This is a very convenient scale which indicates the amount of power amp
headroom left for any signal condition. On this scale, the lowest LED is labeled “00” (infinity), which is consistent with the dB system. If fault
conditions exist, such as a high temp. thermal shutdown or a DC offset at the output (caused by the amplifier itself or externally induced at
the input), this LED will go off and remain off until the faultis cleared. You will also notice that this LED will not light for approximately two
seconds during the power-up sequence, and will go off very quickly during the power-down sequence. This is normal, indicating that the
transient protection circuitry is operating properly. Should both LEDs ever fail to light after the normal power-up sequence, and no other
fault conditions exist, then the mains AC power might not be applied. Such a condition might be a blown fuse . If upon replacing the fuse (with
the same type and rating) it does not clear the problem, then the amplifier will require servicing by a qualified service technician.
DDT™ COMPRESSION
The CS-1000 is a compact and powerful amplifier that features a new type of dynamic compression. This compression system enables the
user to maximize the performance of the amplifier/speaker combination. We have determined through much research that the com pression
circuitry should prevent the power amplifier from running out of headroom (clipping) and should be as simple to operate as possible to avoid
undue complication for the user. This compression system is activated by our exclusive DDT compression circuitry that senses conditions
that might overload the amplifier and activates compression when clipping is imminent. In other words, compression takes place whenever
signal conditions exist which prevent the amplifiers from faithfully reproducing the input signal. Threshold then is clipping itself and no
specific threshold control is provided. This technique effectively utilizes every precious watt available from the power amplifier. Techniques
using external compressors and limiters are usually less effective, limit output power levels and require additional controls, which add
complexity to an already complicated system. The DDT system is an automatic, hands-off approach to the problem of amp clipping. Because
of the dynamics of music and vocals, it is quite common to activate the DDT compression circuitry almost constantly during a high level
performance since this was what it is designed to do; i.e., to maximize the dynamics available from the amplifier within its power output
capabilities regardless of power supply/AC line voltage variations and load impedance selection.
DDT" ACTIVE LED'S (3)
The DDT active LED's indicate when compression is taking place. As long as gain reduction is occurring, the LED will continue to light,
thereby giving a valuable indication of this unique compression function. The DDT function can be defeated on both channels
simultaneously by selecting the defeat position on the DDT compression switch (7) located on the back panel of the CS-1000. When the
compressor is defeated, the DDT active LED now indicates clipping, the condition where the amplifier is failing to faithfully reproduce the
input signal. Defeating the DDT compressor should not be taken lightly or simply as a matter of course. Most loudspeaker systems simply
can not handle the square wave power of the CS-1000 and defeating this valuable limit is only asking for trouble in the long run. Often studio
engineers feel the need to defeat the DDT compressor for fear that it might color the sound in studio listening. Occasionally, external
compressors/limiters are employed to automatically set the level of a particular system and thus, the unknowning technician will defeat the
DDT compressor thinking it is not needed. Those are examples of not understanding the operation of the DDT circuitry. The DDT
compressor is only activated when clipping is imminent. Until this occurs, it's simply a passive friend. The only reason that the defeat switch
is there in the first place is to allow check-out and service technicians to evaluate the power amplifier at clipping. Valuable performance
information, such as ripple and regulation, can only be assessed when an amplifier is allowed to clip. Other than those times, we strongly
suggest that the DDT compressor switch be set in the active position and left that way.
THERMAL SYSTEM
The CS-1000 has a unique thermal system that employs a tunnel-like heat sink design to provide maximum cooling for the 24 power
transistors (12 for each channel). A single 100 CFM fan mounted on the back panel of the amplifier provides an almost unrestricted airflow
through the tunnel to provide the lowest possible operating temperature for the power devices. This approach is so efficient that even music
power operation into 2 ohms will not cause a thermal shtudown unless the ambient air temperature is considerably higher than normal
(above 400 C). Under normal intermittent applications, low speed fan operation will provide adequate cooling. Since the C5-1000 is a
redundant two-channel amplifier, but only one fan is employed, the fan circuitry is an independent system, separately fused internally. You
will notice that the heat sink components are divided horizontally. The lower half contains Channel A output transistors, while the upper half
belongs to Channel B. The fan naturally provides equal cooling for both channels. Each channel has a separate built-in thermal sensor and
separate logic circuitry. If one channel heat sink reaches an operating temperature of 60° C, then its logic will cause high-speed fan operation
regardless of the other channel's operating temperature. In other words, either channel heating will control the fan speed. Under normal
continuous usage at full-rated power output into the rated load, the thermal logic system will continuously monitor heat sink temperatures
and will automatically select the fan speed required to maintain safe operating limits for the power transistors.
HIGH TEMPERATURE LED'S (4)
Ifthe CS-1000 is continuously operated into 2 ohm loads or lower for any considerable length of time or if the ambient temperature of the
air supply were to become too hot to provide adequate cooling even under normal 4 ohm loading situations, then the am plifier internal heat
sinks could reach unsafe operating temperatures. When this occurs, then the thermal logic system will shut down the unsafe channel,
causing the high temperature LED to light and the “0” LED to go out on that channel. Since the CS5-1000 is a redundant amplifier, the
shutdown of one channel will not affect the operation of the other channel. After the unsafe channel cools down to safe limits, operation will
be restored in that channel. Normal operation will be indicated by the high temperature LED off and the “0” LED on. Continued operation
under fault conditions will in no way harm the amplifier, but because of the nuisance factor, steps should be taken to determine the problem
and solve it. Because of the very efficient design of the CS-1000 dissipation system, thermal shutdown conditions will almost never occur
unless there is truly an external fault. For continuous operation, the CS-1000 requires a source of cool air. As an added help in locating
mismatched or shorted speakers, the DDT active LED isa powerful tool. If this LED flashes continuously at relatively low output power levels
(indicated by low power readings on the LED array), itis almost a sure sign that the amplifier loading is too low in value or that there might be
ashort. Remember, usually the power LED array should reach 100% indication before the DDT system is activated on any particular channel.
The CS-1000 also has a fail-safe thermal mechanism built into the unit. If either channel thermal logic system should fail to cause thermal
shutdown in that channel or if the fan itself should fail, then this fail-safe system will shut down the entire amplifier, just as if you had turned
off the power switch. This is just one more protection that Peavey has incorporated into this unique amplifier as a backup system. If this
should ever occur, immediately seek professional help at a Authorized Peavey Service Center.
MAINS POWER SWITCH (5)
The front panel of the CS-1000 contains a conventional type on/off rocker switch. When the amplifier is plugged into a suitable power
source, activating this switch should light both channel “0” array LED's after the power-up delay sequence is completed (approximately two
seconds). You should also be able to hear the output relays close (click). Ifthe amplifier is cool, the fan should start on low speed operation. If
only one channel “0” indicator lights, then the possibility exists that the mains fuse has blown. If neither channel “0” indicator lights, then
check the main power source. It's always a good idea to check to see that the fan is operational, especially on a new unit. The possibility exists
that due to shipping and handling, the fan bearings might be too tight to allow low speed fan operation. If this is the case, immediately seek
professional help. The CS-1000 must have normal fan operation to provide adequate cooling for the unit. Without airflow, the amplifier will
“thermal” very quickly under any signal conditions.
BACK PANEL
The back panel of the CS-1000 contains a “back porch” design which contains the various input and output connectors for each channel.
Also included is the patch panel to provide the user with a very flexible system to facilitate the use of balanced input transformers and dual
crossover networks. These features are unduplicated in any other stereo power amp on the market today. The back panel also includes the
fan opening with protective grille (6) where cooling air is drawn into the amplifier. This opening should never be blocked or restricted.

The CS-1000 is fused with a standard 15 amp, 125 VAC fuse. Always replace with the same type and rating. Failure to do this could void the
warranty on the C5-1000.
MODE SWITCH (16)
The mode switch is located on the “back porch” next to the channel input jacks. This switch converts the CS-1000 from normal stereo
mode to bridge mode. Unless the amplifier is to be used in a commercial sound distribution system (70/100 volt lines), the bridge mode
should not be used. In certain crossover applications, accidental switching to the bridge mode could destroy the speaker system.
Applications of the bridge mode will be covered later in this manual.
PATCH PANEL
The patch panel of the CS-1000 offers many features that make the amplifier more flexible. In order to simplify the explanation, four basic
modes of operation will be introduced. Simplified functional diagrams are printed on the top of the CS-1000 showing these four modes.
These diagrams also appear in this manual for discussion purposes.

STEREO MODE (UNBALANCED INPUTS) (9) (10) (12) (15)
The CS-1000 is shipped from the factory with jumper plugs inserted in the transformer (10) and crossover (12) accessory sockets. These
jumper plugs are necessary if the low impedance connectors (9) are to be used as inputs for each channel. As indicated in Diagram 1, the XLR
connectors are wired in an unbalanced configuration (pins 1 and 2 are ground, pin 3 is input). The unbalanced input configuration is
acceptable whenever relatively short cable runs are employed or when the associated mixer used has a transformer-coupled output. Under
these circumstances, this configuration will usually provide adequate hum and interference rejection for most environments. Notice that the
jumper plugs in the crossover accessory sockets are required to complete the signal patch to the respective power amp inputs (15). If the
normal unbalanced à" power amp input jacks are used instead, then the jumper plugs are not necessary. Itis suggested, however, that they
be left in their respective sockets for possible later usage. As with all Peavey amplifiers, the CS-1000 has two power amp input jacks per
channel (15), which offer considerable flexibility in hook-up possibilities. For monaural operation (the same signal is applied to both
channels), the mixer output is plugged in one of the parallel input jacks in one of the channels and a short shielded jumper cable is then
connected between the remaining input jack on that channel to one of the parallel input jacks on the other channel. This technique is called
daisy-chaining and can be repeated many times to include additional amplifier channels requiring the same signal feed.
STEREO MODE (BALANCED INPUTS) (9) (10) (15)
When conditions require the use of a balanced input at the amplifier, the XLR connectors (9) on either or both channels can be converted to
a balanced configuration by removing the jumper plug from the transformer accessory socket (10) and plugging in an input transformer
module (PL-2). The Peavey model PL-2 transformer moduleis a nominal 1:1 turn ratio-type, resulting in unity gain. As indicated in Diagram 2,
the XL RB connector is now wired as a conventional balanced-type input (pin 1is ground, pin 2 is negative, pin 3 is positive). Again, the jumper
plugs in the crossover accessory sockets are required to complete the signal patch to the respective poweranp inputs (15). If balanced stereo
operation is desired, then two PL-2 modules are required. However, for monaural operation, only one PL-2 is needed, and the inputs are
connected together by placing a short shielded jumper cable between one of the power amp Input jacks (15) on each channel. Obviously, the
¥LR connector associated with the transformer module is the balanced system input and the other XLR connector is not used.

The Peavey CS-1000 patch panel can also be used to biamp and/or provide special equalization capabilities for loudspeaker systems.
Various electronic crossovers and special purpose modules are available in a broad range of frequencies for both Peavey and non-Peavey
loudspeaker systems. More complicated systems, such as stereo biamped, triamped, or even 4-way crossover systems are possible. We
suggest you contact your Authorized Peavey Dealer for details. A typical stereo biamp system will be discussed in this manual.

The purpose of a traditional high-level passive crossover found inside most speaker systems is to separate the low frequency material from
the program and feed it to the woofer (low frequency driver), and to separate the high frequency material from the program and feed it to the
tweeter (high frequency driver). This crossover is connected between a power amplifier and the speakers and, as its name implies, is made up
entirely of passive components (no transistors or tubes). Such a system is usually referred to as “full-range,” which simply means that the
power amplifier must handle the full range of frequencies. There are many good reasons for using a biamplified professional system as
opposed to a full-range system. One reason is that the biamp system will provide more headroom with the same power amplifier complement
than that of the full-range system. The term headroom deserves some consideration. Program material (music or speech) is made up of many
different frequencies and their harmonics. Most music, especially contemporary rock music, is bass heavy. That is, the low frequency
material contains much more energy than the high frequency material. If both high and low frequency material, such as voice and bass
guitar, are present in a full range system, the high-energy bass frequencies can use up most of the power available from the power amplifier,
leaving little (or none) forthe high frequencies. The result can be severe clipping (distortion) of the high frequency material. In a biamplified
system, the high frequency material is routed to its own power amplifier (and associated loudspeaker), which avoids the clipping problem.
This results in an effective increase in system headroom that is greater than would be obtained by simply using a second power
amplifier/speaker combination in full range operation. To biamp then, some type of active crossover is employed in the mixer feed to
separate the low and high frequency material, which is then patched to separate power amplifiers to drive separate loudspeaker
components. Such a system is easily accomplished with the Peavey C5-1000 power amplifier patch panel and associated CS® Series plug-in
active crossover modules.
Referring to Diagram 3, the jumper plugs in both crossover accessory sockets (12) have been replaced by two-way crossover modules.
Also notice that the PL-2 transformer modules are still inthe transformer accessory sockets (10). This configuration now has the makings of
a complete stereo-balanced biamp system. The only thing required is an additional stereo power amplifier, which, together withthe existing
dual power amp sections of the C5-1000, makes up the four independent power amplifiers required for a stereo biamplification system. You
will notice that because of the pin out arrangements of the jumper plugs versus the crossover networks, whenever the jumper plugs are
removed from the crossover accessory sockets (12), the power amplifier inputs for the respective channels are isolated (no longer connected
to anything). In other words, the crossover modules themselves and all associated connectors (as well as the PL-2 transformers and
respective XLE connectors) are islands unto themselves. In this case, two islands with each crossover having a balanced input (9), dual
(parallel) unbalanced inputs (11), an unbalanced low output (13), and an unbalanced high output (14). In order to complete the system,
external patching must be accomplished between the low and high crossover outputs and the various power amp inputs using shielded
patch cords.
Reviewing our previous discussion concerning headroom, bass-heavy program material requires more power for the low frequency
system than the high frequency system. In general, high frequency horn drivers have lower power ratings (power handling capability), but
have high efficiency ratings (sound pressure capability for a given power) than do low frequency woofers. Thus, it might be necessary to use
a smaller power amplifier on the high frequency components and a larger power amplifier on the low frequency components of a biamp
system. Such a system can be achieved using the CS-1000 stereo power amplifier itself for the two low frequency channels, and adding a
Peavey M-7000 for the two high frequency channels. In this case, the low outs (13) of the crossoverislands must be patched to the poweramp
inputs (15) of the CS-1000, and the high outs (14) of the crossover islands must be patched to the power amp inputs of the M-7000. Four
shielded patch cords are required in this configuration. The stereo feeds from the associated mixing system will be patched into the balanced
XLR connectors (9) on the respective crossover islands. The system is then completed by connecting the proper speaker components to the
correct power amplifier outputs. A diagram is included at the end of this manual showing all connections. It is recommended that all
connections be completed and double-checked before applying power. Wrong connections could result in loudspeaker damage. It is also
good practice to apply AC power to the power amplifiers with the sensitivity controls at full counter-clockwise settings (off) and then
gradually bring up the levels to check connections and make sure at low sound pressure levels that the biamped system has proper routing of
highs and lows to the respective amps, horns and bass enclosures. After completion of these tests, the various sensitivity controls should be
set to their normal operational settings (usually full clockwise).
Obviously, for amonaural biamp system (only one mixer feed), only one crossover module is required and only one crossover island will be
used. Inthis case, one channel of the CS-1000 can be patched for the lows and the other channel patched for the highs, resulting in asimple,
compact system with outstanding performance. Again, a word of caution is in order. Since the CS-1000 is capable of producing more than
500 watts RMS per channel into a 4 ohm load, the high frequency components of the particular loudspeaker system must be able to handle
these power levels. Alternatives are to use a smaller power amplifier for the entire biamp system, such as the M-7000 or M-4000, which offer
the same features as the CS-1000.
The Peavey DDT compression system adds a new dimension to biamped systems. Each power amplifier channel has its own Distortion
Detection Technigue circuitry, and each is completely independent. When signal conditions exist which could cause clipping in the low
frequency power amp channel(s), the DDT system will simply limit that portion of the total biamp system. This will in no way affect the high
frequency portion of the biamp system and it is free to increase in level until conditions exist which could cause clipping in that particular
power amp channel(s). At that point, the DDT system will limit the high frequency portion of the system. This is a very effective two-leve|
compression system and will yield sound pressure levels unmatched by conventional broad-band compression techniques.
The Peavey C5-1000 offers maximum flexibility and performance features not found on most competitive units. By thoroughly
understanding the patch panel features, expansion to larger and more complex systems is only limited by the imagination of the user,
Toward this end, we offer the following additional information which may or may not be obvious:
1. A biamp approach is only possible with loudspeaker systems which provide access to the individual speaker components,
bypassing the built-in passive crossover (most Peavey loudspeaker systems offer biamp high and low switching jacks on the back
panel).
2. The crossover module used must have the proper characteristics to match the particular loudspeaker system. Of greatest
importance is the crossover frequency. Peavey offers a variety of plug-in crossover modules which are specifically designed to
match the various loudspeakersin the product line. These crossovers have the correct crossover frequency, high frequency pad
and equalization for the particular loudspeaker, resulting in system performance with a very flat frequency response. Also
available are general purpose crossover modules at frequencies of 500, 800, and 1200 Hz for non-Peavey loudspeaker systems.
3. The outputs of the crossover modules (both high and low) can drive several power amp inputs. The parallel input jacks can be
used to daisy-chain to additional power amps for an expanded system on either the low or high frequency system (or both}.
Remember, the components in most Peavey biampable speaker systems are 8 ohms. All Peavey CS series power amplifiers are
rated at 4 ohms. This means thatthe maximum number of components connected to any one particular power amplifier channel
is two (two horns, two woofers). If additional components are required for additional coverage or projection, then additional
power amp channels are required.
4. The PL-2 transformer module can be removed and the jumper reinstalled in any particular crossoverisland if a balanced input is
not desired or required for the crossover module. In this case, the associated XLR connector (9) is now unbalanced as per
previous discussion. If desired, the parallel unbalanced phone jack inputs (11) may be used to supply signal to the crossover
module. In addition, whenever the XLR connector on a particular crossover island is used (either balanced or unbalanced), the
crossover input jacks (11) can be used to patch out full range signals to other amplifier/speaker systems which are operating in
full range or other biamped systems which required different crossovers.

5. Care must be taken to never remove a crossover module or replace it with the CS-1000 power switch on. The complex circuitry
used in the crossover modules receives bipolar power through the socket, and removal or replacement could cause severe
transients which can destroy the loudspeaker system. Always turn the C5-1000 off first. As an added feature, the bipolar power
for the crossover islands can be supplied from either channel of the CS-1000. Thus, if one channel should shut down for any
reason, the redundancy of the system will maintain operation of the crossovers.
6. The individual sensitivity controls on each channel play a very important role in the use of the crossover modules. As such, they
represent a signal loss when they are operated at another setting other than full clockwise (maximum sensitivity). Biamped
speaker systems usually require less signal level for the high frequency components because they are ge nerally more efficient.
Consequently, a system balance can be achieved by reducing the high pass level. This is particularly important on non-Peavey
loudspeakers where the PL-500, PL-800 or PL-1200 crossover modules must be used. These modules are referred to as “no pad
and equalization” types. As such, there is no reduction in high pass level. Consequently, the pad must be accomplished using the
high pass channel sensitivity control. The amount of pad required is always the difference between the efficiency ratings of the
high and low speaker components. Whenever Peavey loudspeakers are operated using the special crossovers the sensitivity
controls should be set at full clockwise settings (maximum sensitivity) to provide maximum system headroom since the correct
pad and equalization is already provided in the crossover module.
Bridge Mode
The bridge mode on stereo amplifiers is often misunderstood as to the actual operation and usage. In basic terms, when a two-channel
amplifier is operated in the bridge mode, itis converted to a single-channel unit with a power rating equal to the sum of both channels’
continuous power ratings, at a load rating of twice that of the single-channel ratings. For the C5-1000, the bridge ratings are 1000 watts RMS
(continuous) into 8 ohms (minimum load). Bridge mode operation is accomplished by placing the mode switch (16) in the bridge position,
connecting the load between the red binding posts of each channel, and using Channel A as the inputchannel. All fu nctions of Channel B as
an input are defeated. What actually happens from the technical standpoint is that Channel B is supplied an input signal which is equal in
level but is 180° out-of-phase from that of the Channel A input signal (i.e., when Channel A's signal is positive, Channel B's signal is negative
and vise versa). Thus, the load (which is connected between the channels) sees the sum of the output voltages of both channels (which is
then twice that of the single channel), and this load must be 8 ohms or greater.
For the CS-1000, the selection of bridge mode should invoke the following interesting question: “Where would | need a 1000 watt, 8 ohm
amplifier?” When you consider the fact that there are virtu ally no 8 ohm speaker components which can handle 1000 watts RMS (continuous)
safely, there are generally no practical applications for a bridged CS-1000 in simple sound systems. The real purpose is to drive sound
distribution systems in very large public address applications. In the bridge mode, the CS-1000 can supply 70 or 100 volts RMS directly
without matching transformers. 70 volt distribution systems are very common in domestic applications where large numbers of relatively
small loudspeakers are used for background music and paging. Such systems require the use of 70 volt transformers at each loudspeaker.
100 volt systems are more common in export applications. Occasionally a large speaker array might require (or handle) 1000 watts RMS into
8 ohms directly. This then might be a practical application.
Diagram 4 shows the actual arrangement for the CS-1000 patch panel in the bridge mode. Notice the jumper plugs are inserted in the
transformer (10) and crossover (12) accessory sockets of Island A. These jumper plugs cause the XLR connector of this island to be wired in
the unbalanced configuration (as in Diagram 1) and complete the connection to the parallel bridge power amp input jacks (formerly Channel
A power amp input). The Channel A sensitivity control now determines the sensitivity of the bridge mode amplifier. The Channel B power
amp input jacks and sensitivity control have been deleted since they serve no purpose in this mode and are actually electronically removed
from the circuit. Both sets of parallel 14” output phone jacks have been deleted on the diagram since these also are normally not used in the
bridge mode. Remember, the 8 ohm minimum load must be connected between the red binding posts. If individual 4 ohm loads were
connected to each output (as in normal stereo applications) when the bridge mode is selected, Channel A would supply a normal in-phase
signal to its respective load, but Channel B would supply an abnormal out-of-phase signal to its respective load, and both of these signals
would be the Channel A source material (Channel B source material, if present, would be defeated). This is a very dangerous situation,
especially if the individual channels are being used to supply high and low signals inthe typical biamp configuration. Obviously, the speaker
components on Channel B would no longer be supplied their intended signal but rather an out-of-phase version of the Channel A signal,
which could destroy the associated loudspeaker components. To minimize the possibility of this happening on the CS-1000, whenever the
bridge mode is selected, the standby (“0”) LED and the LED array itself on Channel B is defeated (off), just as if there was a fault condition on
Channel B. This provides a positive indication that the CS-1000 is no longer in the stereo mode.
Often technicians fall into what we call "the bridge syndrome.” This is designing a system for bridge mode operation when indeed they
really don’t need it. A typical example is where two 4 ohm speaker enclosures are wired in series, creating an 8 ohm load, and this load is then
driven in bridge mode. In this case, a CS-1000 would deliver 500 watts RMS to each enclosure (a total of 1000 watts for both). A much better
approach is to use the CS-1000 in the stereo mode and then connect one 4 ohm speaker enclosure to each channel of the C5-1000 and
daisy-chain the inputs. Each channel would still deliver 500 watts RMS to each enclosure (a total of 1000 watts for both}, but now you would
have a redundant system with the advantage of being able to adjust the individual levels if that is a desirable feature. Another frequent
application problem is driving a single 4 ohm enclosure in bridge mode. This is simply an example of not understanding that when bridge
mode is selected, the rated load specification is twice that of single channel operation. In this case, under continuous full power operation
the amplifier will thermal out.
Although bridge mode operation is very easy to accomplish on the CS-1000, and we have provided an indication means whenever the
mode is selected, again, a thorough understanding of the patch panel features will allow further expansion to more complex systems. The
following list should provide more information toward these goals:
1. For proper bridge mode operation, both wires of the output must “float” above ground. If either wire were to become grounded,
this would present a short circuit to the associated channel of the CS-1000. As an aid in determining the condition of the
distribution system, the DDT activation LED's on both channels are operational when the bridge mode is selected. Whenever the
CS-1000 reaches full power output, both DDT activation LED’s should flash simultaneously, indicating that DDT compression is
taking place in both channels. This is anormal indication, since in bridge mode with normal loading, both channels should reach
full power simultaneously. If the DDT activation LED on one channel flashes at a much lower signal level than that of the other
channel, this indicates that the bridge loading is not balanced and that one leg may have become shorted to ground. In this case,
steps should be taken to locate the problem and clear it. If both LED's flash at relatively low output power levels, then this
indicates that the total bridge loading is too low in value or possibly shorted across itself. Remember, just as in the stereo mode,
the power LED array (Channel A) should reach 100% indication before the DDT system is activated on both channels.
2. The jumper plug in the transformer accessory socket (10) of channel A island can be replaced with a PL-2 transformer module.
This will convert the XLR connector on Island A to balanced operation and provide a balanced input for the bridged CS-1000.
3. Thejumper plug in the crossover accessory socket (12) of the Channel A island can be replaced with a crossover or other special
purpose plug-in module. As per previous discussion, the associated bridge power amp input jacks (12) are now isolated, and
signals must be patched to this bridge inputto complete the circuit. Obviously, in bridge mode the C5-1000 is only a one-channel
amp. Consequently, to biamp, additional power amplifier channels must be available. Again, a word of caution concerning the
power handling capability of the associated loudspeaker components in order. Unless the components are part of an array
connected in some series/parallel arrangement to distribute the power, biamping with the CS-1000 in bridge mode (1000 watts)
should be avoided.
4. You should notice from Diagram 4 that crossover island B is completely isolated whenever bridge mode is selected, and it is
normally not used. However, it can be used with additional plug-in modules forexpanded and more complicated systems. These
additional patches we will leave to the imagination of the user.
As you can see, the CS-1000 is a very flexible amplifier. We highly recommend that you become thoroughly familiar with every aspect of
operation before connecting any speaker system to it. Pay particular attention to the functions of the patch panel and load impedance. We
have included several patch diagrams for information purposes.
Attention Mr. Service Technician: If the time should ever come for you to sero problems gaining access to the heat tube itself and all
the associated circuitry. Our Service Department stands ready to help you if needed with additional instructions on the correct service
parts. Warning: There are no user serviceable parts or functions inside the amplifier. Disassembly should only be attempted by a
qualified Peavey service technician, and only after the amplifier has been disconnected from the mains power source.
Warning: Voltage levels inside this amplifier could cause severe bodily harm. Always disconnect unit from mains power source and
discharge major electrolytic capacitors before attempting to service. Additionally, the mains power source is switched by amains triac
which is controlled by the front panel rocker switch. Mains power voltage is always present at this triac even with the switch off.
