Private Line - PSC M6 Retro Operation Manual

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. There is second switch located on the right
hand side of the front panel of the mixer and is used to control the "tape" or
"direct" monitoring sources.
"mixers" headphones.
The PSC M6 mixer also contains three additional headphone outputs labeled as
"Director", "Boom 1" and "Boom 2" These three headphone feeds also offer the
same selection of monitoring choices with the exception of monitoring "tape"
D.

PRIVATE LINE:

The two headphone feeds labeled Boom 1 and Boom 2 also are equipped with
"Private Line" circuitry. This allows the mixer operator to speak directly to the
boom operators via the slate microphone without the audio going out any other
outputs such as the main outputs. This is helpful if the mixer operator is located
out of sight of the boom operator. To use the "Private Line" function, you must
simply press the private line button located on the front panel of the M6 mixer.
The private line function will only operate as long as the button is pressed down.
E. BOOM COMM:
The M6 mixer also contains a complete duplex communication system built in.
This system allows the mixer operator and boom operators to communicate
freely with each other in a full duplex mode (similar to telephone conversation).
The rear panel of the M6 mixer contains two "TT" (tiny telephone) connectors that
are labeled Com 1 and Com 2. These connectors have two purposes. They
provide a microphone input and corresponding pre-amplifier and also a logic
signal input to control the comm function. The PSC Duplex communicator cables
are similar to our standard duplex cables in that they provide a talent (boom)
input as well as a boom operator headphone feed. In addition to these common
features, they contain a built in microphone and push to talk switch.

all headphone monitoring functions return to normal.
