Safety Symbol and Message Conventions

Safety symbols and messages described below are used in this manual to prevent bodily injury and property damage which could result from mishandling. Before operating your product, read this manual first and understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operation and maintenance (servicing) instruction in the literature accompanying the appliance.

WARNING

Indicates a potentially hazardous situation which, if mishandled,

could result in death or serious personal injury.

When Installing the Unit

Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.

Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.

Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid using the power cord in close proximity to heaters, and never place heavy objects -- including the unit itself -- on the power cord, as doing so may result in fire or electric shock.

Be sure to attach the supplied terminal cover after connection completion. Because high voltage is applied to the speaker output terminals, never touch these terminals to avoid electric shock.

Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling down and causing personal injury and/or property damage.

External wiring connected to the terminals marked with requires installation by an instructed person.

The apparatus shall be connected to a mains socket outlet with a protective earthing connection.

The socket-outlet shall be installed near the equipment and the plug shall be easily accessible.

Use the supplied rack mounting bracket when mounting the unit in an equipment rack. Remove four M4 x 8 screws on both sides of the unit, and mount the bracket there using the supplied M4 x 16 screws instead.

When the Unit is in Use

Should the following irregularity be found during use, immediately switch off the power, disconnect the power supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock.

·If you detect smoke or a strange smell coming from the unit

·If water or any metallic object gets into the unit

·If the unit falls, or the unit case breaks

·If the power supply cord is damaged (exposure of the core, disconnection, etc.)

·If it is malfunctioning (no tone sounds.)

To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components inside the unit. Refer all servicing to your nearest TOA dealer.

Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.

CAUTION

Indicates a potentially hazardous situation which, if mishandled, could

result in moderate or minor personal injury, and/or property damage.

When Installing the Unit

Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock.

When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.

Do not block the ventilation slots in the unit's cover. Doing so may cause heat to build up inside the unit and result in fire.

Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.

To avoid electric shocks, be sure to unplug the unit's power supply cord when connecting speakers.

Be sure to follow the instructions below when rack-mounting the unit. Failure to do so may cause a fire or personal injury.

·Install the equipment rack on a stable, hard floor. Fix it with anchor bolts or take other arrangements to prevent it from falling down.

·When connecting the unit's power cord to an AC outlet, use the AC outlet with current capacity allowable to the unit.

·No rack-mounting screws are supplied with the unit. Separately prepare the appropriate screws for the rack.

• Keep the amplifier over 10 cm (3.94") away from

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
