TR-91 / TR-92 - Installing the TR-91 and TR-92

5 Installing the TR-91 and TR-92

This section explains how to install the Open-back ceiling speakers, that is:

 Connecting the TR-92 (see Section 5.1)

 Connecting the TR-91 (see Section 5.2)

5.1 Connecting the TR-92

To connect the TR-92, as illustrated in the example in Figure 3, do the following:

1. Connect an audio amplifier (for example, the Kramer 907xl Power/Amplifier

Mixer) to the TR-92 input channels by connecting the:

 Left + and - OUTPUT terminal block connectors on the 907xl to the

CHANNEL 1 INPUT + (8Ω) and – (COM) terminal block connectors on

the TR-92

 Right + and - OUTPUT terminal block connectors on the 907xl to the

CHANNEL 2 INPUT + (8Ω) and – (COM) terminal block connectors on

the TR-92

Alternatively, you can reverse the order and connect the left output on the 907xl to

CHANNEL 2 and the right output on the 907xl to CHANNEL 1.

2. Connect the OUTPUTs to a 70V/100V speaker (for example, the Kramer

Galil 8-C Ceiling Speakers) by connecting CHANNEL 1 to the Left speaker

and CHANNEL 2 to the Right speaker. For each channel connect the COM

terminal block connector to the - speaker connector and the 70V or 100V

OUTPUT terminal block connector to the + speaker connector.

Note that you have to select the same power settings (70V or 100V),

as required, for both channels.

Always switch off the power to each device before connecting it to your

TR-91 / TR-92. After connecting your TR-91 / TR-92, connect its power

and then switch on the power to each device.
