3. GENERAL DESCRIPTION

TOA’s P-9060DH Power Amplifier is a 2-channel amplifier providing 60 W per channel at 83 Ω (70 V line output). TOA’s P-9120DH Power Amplifier is also a 2-channel amplifier providing 120 W per channel at 41 Ω (70 V line output).

Both amplifiers can be used as power amplifiers for the M-9000 (Matrix Mixer Pre-Amplifier) and the T-001T (Audio Output Expansion) and as expansion amplifiers for the A-9000 series (Matrix Mixer Power Amplifiers). Besides, they can be used as power amplifiers for other line output devices, thus covering wide range of applications.

4. FEATURES

Mountable in a standard 19" equipment rack (2 unit size) using the supplied rack mounting bracket.

Input level selector switch (–20 dB/0 dB)

An input signal to Channel 1 can be transmitted to both channels 1 and 2, and the output volume adjusted using the input volume control for each channel.

Electronically-balanced inputs.

Input terminals employ removable terminal blocks to provide maximum connection ease.

Front-mounted LEDs to show status of protection, peak, and input signal level for each channel.

Built-in protection circuitry disconnects the power amplifier's output from the load when unusual temperature rise occurs.

5. INSTALLATION PRECAUTIONS

5.1. When Installing the Unit on the Desk
