Precaution for connection

This unit comprises 7 independent power amplifiers, each being capable of reproducing the same quality sound through its channel. Note that you should connect an input source and a speaker to each channel in use. Leave any unused channels unconnected, if the DTA- 9.4 is used for 2- or 5-channel connection.

Balanced Input (XLR terminal)

Connect controllers or control amplifiers with balanced outputs for high-quality sound.

1. GND

2. Disconnecting the input terminal

Pull out the connection cable while holding down the lever.

Push

Note:

•When using this balanced connection for a specific channel

between the control amplifier and DTA-9.4, set the INPUT SELECT switch to the side (the balanced input side) to select balanced input. Next, use commercial XLR balanced cable and connect the balanced output from the control amplifier to the corresponding balanced input on the DTA-9.4.

Connector ground terminal: Chassis grounded

The pin assignments for this terminal are given above. This pin assignment conforms to the standard adopted by the Audio Engineering Society. Refer to the instruction manual supplied with the control amplifier and verify that its output terminal is compatible with the pin assignments for this terminal. The output terminal of Integra DTC-9.4 is compatible with the pin assignments for the terminal of DTA-9.4.

Input terminal

1. Connecting the input terminal

Match the pins and insert the terminal until you hear a “click.” Make sure that the terminal is locked by lightly pulling the connection cable.

•Do not connect anything to the RCA-type audio input jack.

INPUT SELECT /

This switch is located between the balanced input and single-ended RCA input for each channel. Use this switch to select the input type for its channel.

When pushing the switch to the side, the balanced input is selected. When pushing the switch to the side, the RCA audio input is selected.

Note:

•Do not change the INPUT SELECT switch setting when the DTA-9.4 is turned on.

•Make sure that connections have been made only to the inputs selected with the INPUT SELECT switches and nothing is connected to the other ones.

Unbalanced Input (single end RCA input)

Connect controllers or control amplifiers with single-ended outputs.

RCA type

Note:

•When using this single-ended connection for a specific channel

between the control amplifier and DTA-9.4, set the INPUT SELECT switch to the side (the RCA audio input side) to select single-ended input. Next, use commercial RCA audio pin cable and connect the single-ended output from the control amplifier to the corresponding single-ended input on the DTA-9.4.

•Do not connect anything to the balanced input jack.
