PSC is confident that this new DV Promix 3 Mixer has set new standards for portable mixer technologies and features. Please feel free to contact us if you have any comments or questions concerning your new mixer. Additionally, we invite you to share your suggestions for new products you would like to see developed. Professional Sound Corporation extends a six-month warranty on parts and labor to all DV Promix 3 Mixer owners who return their warranty cards at the time of purchase.

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.
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.
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.
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.
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.
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. C. OUTPUT LIMITERS.
contains limiters that are controlled automatically for ease of use and will provide 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.
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.
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.
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.
“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.
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.
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) Consumer Line Level (-10dB) or Microphone Level (40dBv). These outputs are normally used to feed audio to any device with balanced (XLR) inputs.
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 Above chart represents only a small fraction of the possibilities that exist when interfacing to microphones of every brand and type. We have tried to list common examples for your use.
