For each channel, there is a 1/4” phone jack socket and female XLR socket provided for signal input on the
rear panel of the amplifier. Each is electronically balanced at an impedance greater than 10k ohms.

The phone jack and XLR connectors are internally wired in parallel, and therefore either socket may be used
for the input signal. The connectors not used in this manner function as loop-through connectors for daisy
chaining a number of channels.

The ‘HOT, + or in phase’ connection is to pin 2 of the XLRs and the TIP of the phone jack.

The ‘COLD, -, or out of phase’ connection is to pin 3 of the XLRs and the phone jack RING.

Pin 1 of the XLR’s and the phone jack SLEEVE are internally connected to the chassis. The screen of the input
cable should always be connected to one of these points to ensure that EMC regulations are met. The cable
shield ground should also be connected to the equipment which is providing the input signal.

When feeding the PULSE 4x300 from unbalanced sources, connect the signal conductor to pin 2 of the XLR or
the phone jack TIP, with the cable screen going to pins 1 and 3 of the XLRs or the SLEEVE and RING (if
avaialable) of the phone jack.

For bridge mode operation, channel 1 provides the signal for the 1+2 pair with channel 3 providing the signal
for the 3+4 pair.  Channel 2 and 4 inputs are ignored by the amplifier in bridged mode.
