DESCRIPTION Thank you for purchasing the Professional Sound Corporation M6 Portable Audio Mixer. We are confident that this M6 Mixer has set new standards for portable mixer technologies and features while incorporating a timeless housing design. 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.
INPUTS: A. BALANCED INPUTS The PSC M6 Audio Mixer provides six input channels utilizing female XLR connectors. The studio grade input circuitry is transformer 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.
Because of the PSC M6 Mixer’s “retro” design, we have included the 12T microphone powering. When set to 12T, 12 VDC is applied across pins 2 and 3. Pin 2 being positive and pin 3 being negative. This polarity is know as “standard phase” and is the excepted A.E.S. standard. Some older 12T microphones may have been wired as “Red Dot”. This is the reverse polarity of standard phase and is still in use by a small percentage of 12T microphones world-wide.
H. CHANNEL FADER: The PSC M6 Mixer is equipped with traditional rotary knob faders. This “retro” design is ideal for field use as it is dust and dirt resistant just like your trusty old Sela mixer. Ya baby, it’s 1975 all over again! Typical operating range of the faders is from #4 to #9 position on the fader. OUTPUTS: A. BALANCED OUTPUTS The M6 Mixer contains very high quality custom-made audio output transformers.
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 front panel selection switch and a volume control. The rotary switches are used to control what the operator listens to. These choices include: Left channel to both ears, Right channel to both ears, normal Stereo, a Mono sum of the two channels, Auxiliary 1 and Auxiliary 2.
F. TAPE RETURN The M6 Mixer is equipped with tape returns used to monitor 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 bottom panel of the M6 mixer. The tape/direct switch is located on the upper right hand corner of the front panel.
Ten “D” alkaline batteries can power the M6 Mixer. These batteries are accessed via the battery door located on the side panel of the M6 mixer. When using alkaline batteries, you can expect 6 to 10 hours of operation under normal circumstances. Always observe correct polarity when installing batteries! Note: Never store your M6 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.
The M6 Mixer uses high quality transformers on its inputs and outputs. Transformer topology was chosen for its inherent ability to reject RF, thus making this new mixer perfect for use with multiple RF systems. This new design uses modern semi-conductors from Maxim, Linear Technology National Semiconductor and Burr-Brown to name but a few. These operational amplifiers, voltage regulators and precision voltage references feature low power consumption, low noise and low distortion. C.
