Direct Outputs
The Direct Output from each channel appears
at a 1/4" mono phone jack. Each direct output is
an individually buffered tap of the signal
immediately after it has been processed by the
module. The state of the AX-1000A mixing
system has no effect on the direct signal. For
example, a Compressor Mic Module's direct
output will be compressed by the amount set on
the module itself; however, the direct signal is
not affected when the Internal Mute is invoked;
and it will not gate on and off as the AX-1000A's
automatic mixing circuitry operates.

Direct Output
Each direct output has a 680 ohm series resistor. Recommended load impedance is 5k ohms or greater. Direct
outputs can be tied together and passively mixed. Because each Direct Output is individually buffered, this type of
hard wire mixing does not cause additional crosstalk between channels. However, the level of each channel goes
down in a hard wired Direct Output mix as more channels are added to such a mix.
For example, if Direct Out 1 and 2 are placed in parallel, the signals will mix with a 6 dB drop in channel direct
level. An additional 6 dB drop occurs each time the number of parallel outputs is doubled.
Logic Outputs
Each channel's logic output is an isolated open-collector circuit. When a channel has gated open, the E and C
terminals present a short. Hook up according to standard open-collector procedures.
Note:
Positive DC voltage should never be applied to the E terminal. AC voltage should never be hooked
up across these terminals.
The load on logic outputs should be equal to or
greater than 800 ohms. Maximum rating for logic
output is 30 mA at 24 V DC.
