Peavey Mixer Connections

Automix 4 User Manual

Connections

The inputs to the Automix 4 are balanced. This means that there are three wires for each connection, a positive, negative and

shield. These should be connected to each pin accordingly. Also, each input has mic level connections AND line level connec-

tions. However, only one set can be used at a time. Both connections feed the same gain stage.

For unbalanced connections, the GND and negative terminals must be bridged with a jumper. This jumper should be installed

on the connector side, not the receptacle side of the connector. When un-balancing a mic connection, the phantom power must

be OFF. The example below is typical of mic or line level connections. Only the LINE connection is shown for clarity.

NOTE: On Channels 3 & 4, 48VDC phan-

tom power is constantly supplied to the

microphone inputs. Take care when con-

necting microphone signals. These connec-

tions should be made only when power to

the Automix 4 is OFF.

Insert jumper wire between the negative

and shield pins for un-balanced circuits.

NOTE: On Channels 3 & 4, 48VDC phan-

tom power is constantly supplied to the

microphone inputs. Therefore, an un-bal-

anced microphone connection is not pos-

sible on these Channels. This does not

apply to the Line inputs, however.

NOTE: Unbalanced signal

sources should be located

within approximately six

inches of the Automix 4.
