Important Safety Precautions & Explanation of Symbols
The lightning flash with arrowhead symbol within an equilateral triangle is
intended to alert the user to the presence of uninsulated “dangerous” voltage
within the product's enclosure that may be of sufficient magnitude to constitute
a risk of electric shock to humans.
The exclamation point within an equilateral triangle is intended to alert the user
tothe presence of important operating and maintenance (servicing) instructions
in this manual.
The lightning flashes printed next to the output terminals of the amplifier are
intended to alert the user to the risk of hazardous energy. Output connectors
that could pose a risk are marked with the lightning flash. Do not touch output
terminals while amplifier power is on. Make all connections with amplifier
turned off.
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE
COVER. NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSON NEL.
WARNING: To prevent fire or electric shock, do not expose this equipment to
rain or moisture.

SELECTING STEREO, PARALLEL, OR BRIDGE MODE
The amplifier can be set for normal Stereo operation, Parallel input Mode, or
BridgeMono Mode.
Stereo Mode - Each channel remains independent. The amplifier may be used
for two different signals.
Parallel Mode - This setting connects both inputs together. One signal feeds both
channels. Each channel's Gain control and loudspeaker connection remain independent.
Bridge Mode - This setting combines both channels into A single channel with twice
the output power. Use only the first channel's input and Gain control.
Do not connect different inputs to any side that opposites the channel
when operating in Parallel or Bridge Mode.

XLR INPUTS
Each channel has a balanced 3-terminal XLR input. Inputs are
connected with standard cables and can be changed quickly. Pinouts are
marked on the rear panel and shown in the illustration.
The input impedance is 20k ohm balanced or 10k ohm unbalanced.
Balanced connections are recommended to reduce AC hum and interference,
especially with long cable runs. Unbalanced connections may be suitable for
short cables. The signal's source impedance should be less than 600 ohms.
.
OUTPUTS
Wiring connections are shown on the back of the chassis.
BINDING POST OUTPUTS
Stereo and Parallel Mode: Wires are shown by loudspeaker symbols 1 and 2.
Bridge Mode: Wire is shown by Bridge Mono loudspeaker symbol.
SPEAKON OUPTPUTS
Each channel accepts a normal 2-wire cable. In addition, Channel1accepts
4-wire cables for single cable stereo or bi-amp connection.
OUTPUT TERMINAL SAFETY WARNING!
Do not touch output terminals while amplifier power is on.
Turn off the amplifier before connecting, or else there will be risk
of hazardous energy!
Stereo and Parallel Mode- Connect each loudspeaker to its own
channel of the amplifier, just as shown on the left side of the chassis label. The
Mode configuration switches must be set for Stereo or Parallel Mode.
Bridge Mode- Bridge Mode configures the channel to drive a single
audio circuit. And the Mode configuration switches must be set for Bridge Mode.
Connect the load as shown on the right side of the binding posts or to the
left of Channel 1 s Speakon. 4 ohms is the minimum impedance for
Bridge Mode use.
Do not use less than 4 ohm load in Bridge Mode!
Note polarity of connection for Bridge Mode.
OUTPUT WIRING WARNING:
CLASS 2 WIRING SHALL BE USED. FOR BRIDGE MONO MODE,
CLASS 3 WIRING SHALL BE USED.
GAIN CONTROLS
Turn the Gain controls clockwise to increase Gain and
counterclockwise to decrease Gain.
LED INDICATORS
Displays
The LED displays for each channel operate as follows:
PWR
A/P
Green
Main power supply active on this channel.
Red
Shows activity of Limiting circuit, which responds
to both clipping and to thermal overload.
Protect Red Flashes as amplifier approaches
maximum temperature.Illuminated steadily plus
flashing during thermal
Typical Power Switch Operation
When the amplifier is first turned on, the green POWER displays will light up , and there will
be a 2-second turn-on delay, during which all red LEDs will be bright (PROTECT and CLIP).
If a channel will not come out of muting, it may be responding to an excessive high frequency
level at the input . Turning down the Gain controls (while the amp is in the normal condition)
allows the muting to release, and it is always a good idea to prevent an unexpected input signal
from overdriving the load. Signals are shown by the increasing signal intense of the green Sig,
green -20dB and yellow -10dB display.
When the amplifier is turned off, muting should be stopped instantly, while all red LEDs
illuminate until the power supply discharges.
CLIP is illuminated at full brightness
when the output is muted
(PROTECT LED is on, too).
If CLIP is illuminated at less than
full LEVEL display, the load may be
shorted or abnormal. PROTECT
may flash, too.
Key to LED representations:
Not Illuminated
CLIP flashing at full LEVEL display
indicates the amp has reached full
power (clipping) and the limiter is
acting to prevent severe overdrive.
Full Brightness
Variable or
Occasional Flashing
Flashing
The amplifier is in hotreducing
condition when the protect LED
starts to flash.
PROT flashes quickly as the
amplifier approaches max
temperature. Meanwhile,
CLIP lights up and the amplifier
begins thermal protection.
Full Bright
& Flashing
Overheating:
A. If ventilation is blocked, or if the amplifier is overdriven into low impedance
loads, it can overheat. The thermal protection system s normal response to
rising temperatures is as follows:
25 50 : Fan runs on low speed.
50 60 : Fan Speed rises gradually from slow to full.
75 : PROTECT LED starts flashing.
85 : PROTECT flash rate increases, and CLIP starts to glow steadily. The
limiter will begin to reduce amplifier gain, up to 15 dB.
90 : Full muting occurs, as indicated by bright CLIP display and bright
PROTECT display (with rapid flashing superimposed). Full muting
should occur only if the load is shorted, ventilation is completely
blocked, or the fan fails.
