Monitor 2 & 3
Expanded monitor selection - includes tape return and M/S decoding.
All mix buses can be assigned independently.
M/ST/MS - Mono, stereo, or MS decode.
Note: CS 208 D chassis also has a mono/stereo switch on the rear panel, to enable both mono or
stereo wired headphones to be used.
In Mono (rear panel switch), the L & R outs are fed to the tip of the 1/4” stereo jack socket. The ring is
not connected, so a mono plug can be used. When using mono phones, the front panel switch
can be set to either stereo or mono.
Stereo Phones:
Select mono on front panel to assign (1) bus to both headphones capsules.
Meter bridge switches:
Power;
Internal / External:
Switch to internal when using batteries. It is recommended to use alkaline D cells.
Rechargeable (Nicad cells) may also be used with reduced battery life. Pin 3 of power XLR is
the positive charger input. Pin 1 - negative.
Light:
Supplies 12v DC to the BNC connector. A Littlite may be mounted to this
connector. Be aware that a battery operated light bulb consumes considerable
current.
Mix. Bus:
These are inputs only. Another mixer output may be inserted at this point to
increase the number of input channels. Note: A resistor needs to be
installed in line with each input. An interface box is available (CSMB) with a ‘D’
connector and four XLR’s with in line resistors.
Power Supply
Suggestions:
An external AC to DC power supply may be connected to Pin 1 (-), Pin 4 (+) of the
XLR-4. The requirements are that output voltage is regulated and filtered, with a
DC voltage level of 12 to 24 volts and a current rating of > 1 Amp. We recommend using a
linear type supply (rather than a switching type) as, in general, the output ripple & noise of the
supply is less. Some switching supplies can output high frequency noise that can interfere with
the internal DC-DC converter & microphones that have internal converters.
Side Panels:
1/4” - 28 holes are provided to mount the mixer to a cart.
Screws can be up to 1” long (25.4 mm)
