‘Phones 2 & 3’

‘PL’ assigns private line to these outputs.

Main to AB/CD

Assigns either A, B or C, D to the phones outputs.

Main/AUX

Assigns either main A, B, C, D or Aux. 1, 2 to the outputs.

(Note: Left out = A, C, A1; Right out = B, D, A2.)

Phones Select

Further sub-selects signal to the outputs.

(eg: Phones 2 could be A only.) (Main to AB to L.)

X Phones 2, 3 follow the phones 1 selection. For example, tape return (playback) can be directed to these

outputs. (Phones 2 & 3 are completely independent from each other.)

Run 1A - This is the unmarked position to the left of ‘L’ on the phones 2, 3 select switch.

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 (eg: 10 k) needs to be installed in line with each input. An interface box

is available (CSMB) with a ‘D’ connector and four 1/4” jacks 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. A 30 watt linear power supply is very suitable. We recommend

using a linear type supply (rather than a switching type) as, in general, the output ripple and 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).
