Priority Connections
Input 1
Closing the priority contacts will cause all other inputs to be muted by greater than 40dB
Inputs 2–5
Closing the priority contacts 2 to 5 will cause all other inputs to be muted assuming no other
input was already accessed. These inputs operate on a ‘first-come-first-served’ principle;
priority will not be established if another input had gained priority by being used first.
Input Connections
Inputs 1–5
Microphone inputs 1 to 5 are balanced and use an XLR / ¼” 3-pole jack combination socket.
The connections on an XLR plug are numbered 1 to 3 and should be connected as follows
Pin 1: Ground (or Screen). Pin 2: (or Hot). PIN 3: Signal- (or Cold)
If the signal source is not balanced then Pin 1 should be connected to Pin 3 along with the
Ground (or Screen).
The ¼” 3-pole jack socket wiring is shown below.

Sleeve (Screen)
Each of the inputs 1 to 5 is provided with a gain control on the rear panel. This control
adjusts the sensitivity of the input to allow for a wide range of input sources. Adjust this
control to reduce noise and provide an acceptable, undistorted output level.
Input 6
Input 6 uses a phono connection (see below)

Sleeve (Screen)
The two phono sockets allow connection to a stereo signal source (such as a CD/MP3
player). However, both channels are connected together internally to provide only mono
reproduction.
