Isolated Distributed Line Outputs:

ISA 300Ti, ISA 500Ti, and ISA 800Ti

Models Only

Wiring connections are shown on the back of the chassis. STEREO and PARALLEL connections are shown on the right side of the terminals, and BRIDGE mode is shown on the left side. Carefully note the polarity marks, which are arranged to make Bridge Mode connections easier.

Stereo and Parallel Mode- Connect each 70V/100V cir- cuit to its own channel of the amplifier, as shown on the label, right of terminals. The mode configuration switches, page 6, must be set for Stereo or Parallel mode.

Bridge Mode- Bridge mode configures the amplifier to drive a single 140V/200V audio circuit. See page 6 to set the Bridge Mode switches. Connect a jumper wire between CH1 [0] and CH2 [0] terminals.

Connect the load as shown on the label, left of the termi- nals. Connect only 140V/200V distributed audio circuits in bridged mode. Use Stereo or Parallel mode channels to drive 70V loads.

OUTPUT TERMINAL SAFETY WARNING! Do not touch output terminals while amplifier power is on. Make all connections with amplifier turned off. Risk of hazardous energy!

WARNING! Class 2 wire shall be used. For isolated distributed 140V and 200V, Class 3 wire shall be used.

ATTENTION! BRIDGE MODE CONNECTIONS: Connect a jumper wire between CH1 [0] and CH2 [0] terminals. The isolated output feature requires this jumper connection for bridge mode operation.

DataPort

The DataPort V2 connects to optional QSC accessories and processing devices. DataPort devices provide remote mon- itoring, DSP processing, filter and crossover functions.

Amplifier Standby is not supported.

If using the DataPort for input signals, do not use the Ter- minal Block or XLR inputs.

If the amplifier is being used in a system monitored through a QSC cinema monitor (or other QSC DataPort V2 supporting product) CH1 and CH2 output voltages and AC power status will be reported by the DataPort.

70V/100V Stereo or Parallel connection: Each 70V/ 100V zone connects to its respective channel. Ensure that all speaker connections maintain proper polarity.

140V/200V Bridge connection: Wire each bridged pair to a 140V/200V circuit as shown. Connect a jumper wire between CH1 [0] and CH2 [0] terminals. Check for proper polarity.

DataPort V2 connector.

NOTE! If using the DataPort V2 connection for signal

input, the unused XLR or ter- minal block connectors may be used for daisy chaining the input signal to other amplifiers. However, note the signal will be 10 dB down from the signal applied to the DataPort.
