INPUTS:
A.
BALANCED INPUTS
The PSC DV Promix 3 Audio Mixer provides three input channels utilizing female
XLR connectors. The studio grade input circuitry is electronically balanced for
improved RF rejection and in-field practicality. The XLR connectors are wired as
follows: Pin 1 shield (ground), Pin 2 Audio high (in phase), Pin 3 Audio low (out of
phase). Balanced wiring enables longer cable runs without the worry of
excessive noise due to nearby electromagnetic and radio frequency interference.
These balanced inputs may be unbalanced if desired. Either pin 2 or 3 may be
tied to ground (pin 1) to unbalance the inputs of the DV Promix 3.
6
B.
INPUT LEVELS
The PSC DV Promix 3 Mixer can accommodate a wide range of input levels.
Microphone levels of all types can be handled as well as line level signals. The
input range of the DV Promix 3 Mixer is –60dBu to +4dBu. Thus the DV Promix
3 is compatible with all forms of consumer and professional audio equipment.
The input level switches are located to the left of each input XLR connector.
These input level switches provide for three level settings: “D” Dynamic
Microphone (60dB gain), “C” Condenser Microphone (45dB gain), and “L” Line
Level (0dB gain) These input level gain settings are used to correctly interface
sources of varying levels to the DV Promix 3’s preamplifiers. Correct level
matching ensures maximum headroom and the lowest possible noise floor. For
most circumstances, you should use the “Dynamic” setting for use with Dynamic
(non-powered) microphones such as the Shure SM-58 or Electro-Voice RE50.
You should use the “Condenser” setting when you use microphones such as the
Sennheiser ME-80/K6, Audio Technica AT-897 and other powered shot gun style
microphones. You should use the Line Level setting when connecting line level
sources to the DV ProMix 3 such as CD Players, MP3 Players and wireless
receivers with line level outputs. Keep in mind that dynamic microphones have a
low inherent output level that requires that the pre-amp provide maximum gain,
condenser microphone have a higher output level and thus require somewhat
less pre-amplifier gain and line level sources do not require any gain from the
pre-amplifier.
PLEASE SEE THE INPUT SETTING CHART AT THE END OF THIS MANUAL
FOR FURTHER RECOMMENDATIONS.

C.
MICROPHONE POWERING
The DV Promix 3 Mixer can accommodate the most popular microphones used
today. The microphone powering switches are located directly left of the input
XLR connectors. They can be switched to either Dynamic (D) or 48Phantom
(48PH).
In the Dynamic position the mixer provides no microphone powering. This
position is used with Dynamic Microphones, Line Level inputs and when using
Wireless Receivers.
In the 48 Phantom Position the mixer provides 48 volts DC to power 48PH
microphones or simplex powered microphones with a range of 9 to 52 volts. Pin
1 is ground while pins 2 and 3 carry 48 volts DC. The term “phantom” is derived
from the fact that there is no voltage potential developed across a dynamic
microphone transducer that would interfere with its operation. However, most
portable wireless receivers will not operate properly with 48PH turned on. We
strongly recommend setting inputs to dynamic for use with all wireless systems.
**NOTE** Only use the 48PH microphone power when using microphones
that are designed to operate from 48PH. When in doubt, check the
operational instructions that came with your microphone.
PLEASE SEE THE INPUT SETTING CHART AT THE END OF THIS MANUAL
FOR FURTHER SUGGESTIONS.

D.
LOW CUT FILTERS
Low cut filtering is important in location recording where wind noise can cause
pre-amplifier overload. This effect can be minimized by switching the low cut
filter setting to either 80Hz or 150Hz. Each input channel of the DV Promix 3
Mixer is equipped with a low cut filter. These filters are activated via the three
way switches located to the left of the adjacent channel fader knobs. These
filters will attenuate all frequencies below a preset frequency at a rate of 6dB per
octave. When set at “20Hz”, frequencies below 20 Hz are effectively rolled off
with the mixer operating at full frequency response. Optional low cut filter
settings of 80Hz and 150Hz will roll off the frequencies below these figures at a
rate of 6dB per octave (-3dB level at 80Hz and 150Hz respectively). Always use
the minimum filter setting required for the job. For example, if you are indoors or
outdoors on a windless day, use the 20Hz setting. For outdoor use with low wind
conditions, use the 80Hz setting. For recording in high winds, use the 150Hz
setting.
E.
CHANNEL GAIN
In order to limit noise and increase headroom, the channel fader controls are
located in the feedback path of the pre-amplifiers. This provides continuously
variable gain rather than just a decrease in channel output level when an
overload situation occurs. This results in increased headroom and lower chance
of signal clipping (severe distortion).
9
F.
CHANNEL PANS (CHANNEL ASSIGNMENT SWITCHES)
The new DV Promix 3 Audio Mixer contains front panel mounted pan switches.
These pan switches are used to route the individual input channel’s signal to
either the left or right summing buss and subsequent left and right outputs.
When set to the left position, audio from that particular input is routed to the left
output only. When set to the center position, audio from that particular input is
routed to both left and right outputs. When set to the right position, audio form
that particular input is routed to the right output only. These functions are easily
viewed when watching the meters. If you have a particular input set “panned” to
the left only, you will see the audio register on the left output meter only. The
same holds true for inputs panned to the right. In that case, you will only see
activity on the right meter.
OUTPUTS:
A.
BALANCED OUTPUTS (XLR Connectors)
The DV Promix 3 Mixer contains very high quality electronically balanced
outputs. This circuitry has been designed to provide wide bandwidth, low
distortion and real-world ease of use. These outputs are available via the right
hand panel mounted male XLR connectors. These outputs are switchable
between line or microphone levels. At the line level setting, the mixer outputs
deliver a nominal 0dBv signal into 10K Ohm loads. When set to microphone
level, the outputs supply a nominal –50dBv signal levels ensuring compatibility
10
with cameras that feature only microphone level inputs. These outputs have
been designed to offer flexibility in output signal levels depending on the type and
wiring of your cables. The line level (0dBv) and Microphone Level (-50dBv) are
only the nominal balanced output signal levels. Other levels are available when
using these outputs in an unbalanced mode. For example, if only pin #2 is used
with respect to ground (pin 1) the DV ProMix 3 will provide a nominal line output
level of –10dBv. This level is compatible with several cameras such as the PD150.
PLEASE SEE THE OUTPUT LEVEL INTERFACING CHART AND CABLE
RECOMMENDATIONS AT THE END OF THIS MANUAL FOR FURTHER
SUGGESTIONS
B.
OUTPUTS, 3.5MM
The DV Promix 3 Mixer is also equipped with a 3.5mm stereo jack that outputs
signals at microphone level (-50dB). This output can be used to feed audio to
cameras with only a 3.5mm audio input jack. This output is protected from the
microphone bias supplied by most cameras on their external microphone input.
11
C.
OUTPUT LIMITERS.
The limit threshold (activation level) is factory set at +2 on the meter. The limiters
compress the signal at approximately 2.7 to 1 ratio. This is to say an increase of
2.7dB in input signal will result in only a 1dB increase in output signal. Most video
cameras have limited audio track headroom and can easily be overloaded
resulting in distortion of the recorded audio. For this reason, the DV Promix 3
contains limiters that are controlled automatically for ease of use and will provide
and high quality recordings.
D.
HEADPHONE OUTPUT
The Headphone output is located on the right side panel of the mixer. The DV
Promix 3 Mixer’s headphone amplifier circuitry is designed to drive virtually any
headphone with an impedance rating of 32 to 600 Ohms. The headphone
circuitry is controlled by the use of a switch and a volume control that are
conveniently located on the front panel. The switch is used to control what the
operator listens to. It allows the operator to chose between monitoring “MIX” (the
audio that is present on the mixer’s output) and “TAPE” audio that may be fed
back from the headphone jack of the camera ensuring that audio has made it to
the camera. This “TAPE” function is commonly called tape confidence
monitoring. It should be noted that many DV Cams are not equipped with Tape
Monitoring heads and thus do not provide a true tape monitor function. Even so,
the “Tape” monitor function on the DV ProMix 3 is still very useful as you can use
it to verify that your audio cabling between the DV ProMix 3 and your camera is
working and that your levels are properly matched. For example, if you
mistakenly set your DV Promix 3 to line level outputs and then connected it to
your cameras microphone input, when monitoring “Tape” you would hear that the
audio coming back from the camera was severely distorted. This feature is
helpful when trouble shooting audio problems in the field. For more trouble
shooting tips, please see the trouble-shooting guide in the back of this manual or
in our “QUICK START GUIDE”.
*SAFETY NOTE* ALWAYS TURN DOWN THE HEADPHONE VOLUME
BEFORE PLUGGING IN YOUR HEADPHONES.
12
E.
TAPE RETURN
The DV Promix 3 Mixer is equipped with a 3.5mm jack for use in monitoring tape
confidence heads from most any recording device. These tape monitor
amplifiers can be adjusted to match the signal levels of most any device. These
levels are adjusted using a small jewelers screwdriver (or “Greenie” screwdriver).
The adjustment points are located on the back panel of the mixer. The
tape/direct switch is located on the upper right hand corner of the front panel.
When set to ”MIX” the phone amplifiers to monitor the mixers output signal. If
switched to “TAPE”, then the phone amplifiers monitor the tape returns from the
camera. To properly adjust the tape return amplifiers, you must first connect a
tape return cable from your camera's headphone jack to the tape return jack on
the DV Promix 3. Then set the cameras headphone volume to a nominal value
(mid point). Next set the DV Promix 3’s headphone Tape/Mix switch to Mix and
then speak in a normal volume into one of your microphones. Adjust that
microphones channel fader to get a nominal meter reading with peaks just
lighting the “0” meter segment. Now adjust the mixer's headphone volume
control until you have a proper volume level in your headphones while listening to
the microphone. When you switch the Tape/Mix switch to Tape, you should
adjust the tape return trim pots located on the rear panel of the mixer until you
get a similar volume to that of the “mix” setting. You may toggle the switch back
and forth between Tape and Mix while making these adjustments to ensure that
you have the same volume between the two settings. Now that this is calibrated,
you can monitor the audio coming back from the camera while you mix ensuring
that good quality audio is being recorded on your camera’s tape.
13
METERS:
Meters Showing –10dB Signal Level (Signal level too low, correct by
raising input fader level)
Meters Showing 0dB Signal Level (Signal level O.K. , your faders are set
correctly)
Meters Showing +2dB Signal Level (Signal level too high, correct by
lowering input fader level)
14
A.
PEAK READING METERS
The DV Promix 3 Mixer is equipped with a custom made LED meter. We
designed this meter to be easy to read and camera emulating. Because the
most common use of this type of mixer is with DV Cams, we designed the DV
Promix 3’s meters to emulate the peak reading attributes found on many DV
Cams. In this manner, you can be confident of your recording levels even when
the DV Cam is being fed via cable or wireless transmission. Proper recording
levels are very important. Audio signals that are recorded too low are hard to
hear and generally noisy. Audio signals that are recorded too high will be
distorted and unintelligible. Always try and operate the mixer so that the audio
signal level just begins to light the “0” (Amber colored LED) on signal peaks
(occasional flashes, not solidly lit). Under normal conditions such as recording
dialog, when the person is speaking you want the lower meter segments (-20, 10, -7) to be solidly lit and the –5 and –3 and –1 segments to flash on with the
peak amplitude of their voice. If you consistently have only the very low-level
segments lit such as the –20 or –10 segments, you are operating the mixer too
low and need to increase the level of the input fader. If you consistently have the
+2 or +3 segments solidly lit, you are operating the mixer at too high a level and
need to reduce the level of the input fader. This may take a little practice, but it is
well worth the effort. Proper recording levels will produce high quality recordings
and your clients will appreciate the effort.
REFERENCE OSCILLATOR:
Your DV ProMix 3 is now equipped with a reference tone oscillator. This feature
is found on all professional audio mixers and is used to provide a reference tone
level at the beginning of each videotape and/or DVD. It is used for two purposes:
First, when shooting multi camera shoots, you want a consistent audio level from
all cameras when it’s time to edit the various shots together. Nothing is more
annoying than having the audio levels go up and down with each edited shot. To
stop this from happening, you must have consistent audio levels throughout your
tapes. To accomplish this, you must have some point of reference to start with
and this is where the reference oscillator comes into play. Secondly, even if you
are only using one camera, you still want the DV ProMix 3’s audio meters to be
matched up with those of the cameras. Once that is done, you can monitor your
audio levels from the DV ProMix 3 only rather than having to mix from the DV
ProMix 3 and keep track of your audio levels on your camera. In both of these
uses, single camera and multi camera, you should start each tape by turning on
the reference tone oscillator and noting that the DV ProMix 3’s meters will read
15
“0”. Once noted, adjust your camera’s meters to read “0” as well. Once your
camera’s meters are adjusted to match the meters of the DV ProMix 3’s meters,
you can turn off the reference tone oscillator. This procedure generally requires
only about 20 to 30 seconds to complete and will help you produce higher quality
audio in the field. If you are using multiple cameras or you must edit together
tape shot over multiple days, these segments of tone recorded at the beginning
of each tape or at the beginning of each days shoot will come in handy. When
you edit the tapes together, you must simply adjust the audio level on your
editing software to match the “0” Tones. Once this is done, all of your audio will
be of consistent level and thus much better comprehended.
POWERING:
A. INTERNAL POWER, ALKALINE BATTERIES
Two “9 Volt” alkaline batteries are normally used to power the DV Promix 3
Mixer. These batteries are housed in a convenient battery compartment located
on the rear panel of the mixer. When using two alkaline batteries, you can
expect 4 to 6 hours of operation under normal circumstances. In an emergency,
the mixer will operate from one battery, but battery life will be substantially
reduced. Please note there is a polarity to the batteries and they must be
installed correctly. You will note that there are polarity markings inside the
battery drawers. Before installing the batteries into these holders or “drawers”
take a look into the holder itself and note the + and – symbols.
Note: Never store your DV Promix 3 Mixer for extended periods of time with
alkaline batteries installed in the mixer. There is a possibility that the
batteries may leak causing corrosion of the mixer. Battery leakage and the
resulting corrosion damage is not covered under the DV Promix 3 Mixer
warranty.
B. EXTERNAL POWER
The PSC DV Promix 3 Mixer can also be externally powered from any source of
DC power from 7 to 16 Vdc. The mixer consumes a minimum 70 mA over this
voltage range. The external power connector is located on the rear panel of the
mixer. Pin outs of this connector are as follows:
Center Pin (+) Positive
Outside Ring (-) Negative
16
Center Pin diameter = 2.5mm
This external DC input is protected from reverse polarity. If you inadvertently
connect external power of the incorrect polarity, the mixer will not be damaged; it
simply will not power up.
CONSTRUCTION
A.
CHASSIS
The new DV Promix 3 Mixer chassis has been designed for high degree of
torsional rigidity. This increased rigidity provides a stable base for the mixers
modern electronics. The complete chassis is formed from 0.040” aircraft
aluminum. All punching is done on a computer controlled rotary turret punch
press for extreme accuracy. In addition, through careful design, we have
managed to keep the overall weight of the DV Promix 3 Mixer to 1Lb, 11oz.
(0.8Kg) Total.
The mixer’s sheet metal is hand-formed using various press brake setups. The
housing parts are then painted. All silk-screening is then applied.
B.
ELECTRONIC TOPOLOGY
The new DV Promix 3 Mixer was designed from a clean sheet of paper. It
utilizes completely new circuitry designs based upon the latest advances in semi
conductor technology.
This new design uses modern semi-conductors from such sources as Linear
Technology, National Semiconductor and Texas Instruments to name but a few.
These operational amplifiers, voltage regulators and precision voltage references
feature low power consumption, low noise and low distortion.
C.
ENVIRONMENTAL OPERATION
Your new DV Promix 3 Mixer has been designed to operate under extreme field
conditions. The electronics have been designed to operate over a temperature
range of -4 to 158 degrees Fahrenheit (-20 to +70C) less the affects on batteries.
This in addition to the DV Promix 3’s ability to operate under high humidity
conditions makes it perfect for harsh field conditions.
INTERFACING
A.
TO PROFESSIONAL DV CAMS (XLR CONNECTORS):
17
The PSC DV Promix 3 Mixer is especially designed for easy interfacing with all
popular DV Cameras. The DV Promix 3 is equipped with two XLR male
connectors on the right side panel. These XLR outputs can provide audio at
either Line Level (0dBv) or Microphone Level (-50dBv). These outputs are
normally used to feed audio to any device with balanced (XLR) inputs. You can
connect your DV Promix to most, but not all cameras with XLR input connectors
using standard XLR microphone cables. Keep in mind that you must match up
the output level of the DV Promix 3 to the input level required by your camera.
I.E. if your camera has microphone level XLR inputs, then set the DV Promix 3’s
output level switches to “MIC”. On the other hand, if your camera accepts line
level inputs, then you may set the output level switches to “Line”.
B:
TO PRO-SUMER CAMCORDERS (3.5MM JACK):
The PSC DV Promix 3 is also equipped with a dedicated microphone level output
designed to interface the mixer with cameras that are only equipped with a
3.5mm external microphone input jack. To interface this mixer to these types of
cameras, you simply need to plug in one end of the supplied 3.5mm cable to the
DV Promix 3’s “MIC” output jack and the other end into your camera’s external
MIC input jack. The DV Promix 3 has special circuitry incorporated to block your
cameras built in mic powering from interfering with the DV Promix operation.
18
C:
TO WIRELESS MICROPHONES:
Receivers:
The DV Promix 3 Mixer will easily accept the output signal from virtually any
wireless receiver. It can accept microphone or line level signal via a simple
switch setting. Please note that most wireless receivers are not compatible with
48PH. You should always set the DV Promix 3’s MIC powering switch to “D”
dynamic when using wireless receivers.
Transmitters:
The DV Promix 3 Mixer can also be used to send audio signals to DV Cams via
wireless transmitters. The use of transmitters is normally accomplished by
connecting the DV Promix 3’s output XLR to the audio input of the specific
transmitter. Many transmitter manufacturers supply application specific cables
for this purpose. The DV Promix 3 Mixer has been designed to minimize RF
interference through the use of balanced outputs and other RF filtering. It is
important to note that transmitter placement greatly affects transmit range and
clarity. For best results, transmitters should be mounted away from the mixers
metal surface allowing unimpeded RF radiation from the transmitter. When the
mixer is worn over the shoulder of the operator, you should mount the wireless
transmitters to the shoulder strap for best operation.
