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.

WARNING

Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury.

Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.

WARNING

CAUTION

• The unit is designed exclusively to be mounted in an equipment rack. 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.

· Be sure to use the screws with a diameter of over

5 mm (0.2") and length of over 12 mm (0.47") to mount the unit.

· When connecting the unit's power cord to an AC

outlet, use the AC outlet with current capacity allowable to the unit.

When the Unit is in Use

• With the HPF ON/OFF switch kept to the OFF position (factory preset), operating the unit for long periods of time while the Peak indicator is illuminated due to excessive input signal may damage the connected speakers, possibly resulting in fire. Operating the unit with the HPF ON/OFF switch set to the ON position may decrease the possibility of speaker damage or fire due to excessive input signal.

• Make sure that all volume controls are set to minimum position before power is switched on. Loud noise produced at high volume when power is switched on can impair hearing.

• Do not operate the unit for an extended period of time with the sound distorting. This is an indication of a malfunction, which in turn can cause heat to generate and result in a fire.

• Contact your TOA dealer as to the cleaning. If dust is allowed to accumulate in the unit over a long period of time, a fire or damage to the unit may result.

• If dust accumulates on the power supply plug or in the wall AC outlet, a fire may result. Clean it periodically. In addition, insert the plug in the wall outlet securely.

• Switch off the power, and unplug the power supply plug from the AC outlet for safety purposes when cleaning or leaving the unit unused for 10 days or more. Doing otherwise may cause a fire or electric shock.

When a bridge connection is made, each model can be used as a 2-channel stereo amplifier or as a 3-channel amplifier. Their wide range of applications include stores and permanent sound systems.

4. FEATURES

• 2U rack mounting size*.

• Low power consumption and light weight.

• An input signal to Channel 1 can be routed to all channels, and the output level adjusted using the input level control for each channel.

• Electronically-balanced inputs.

• Input terminals employ removable terminal blocks and XLR type connectors to provide maximum connection ease.

• Input/output status LED indicators for each channel.

• Built-in protection circuitry disconnects the output when a short circuit, overload, or unusual temperature rise occurs.

• Equipped with the terminals used for internal information monitoring (power supply, protection status, and fan operation) and power ON/OFF control from external equipment.

* 1U size = 44.5 mm or 1.75" (reference size)

An all-pole mains switch with a contact separation of at least 3 mm (0.12") in each pole shall be incorporated in the electrical installation of the building.

The lighting flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

5. HANDLING PRECAUTIONS

• Keep the input cable away from the output cable. If installed close to each other, oscillation could occur.

• To avoid unit failures, never connect outputs of 2 or more units in parallel.

• Only connect speakers with an impedance equal to or greater than those specified. Connecting speakers with a smaller than specified impedance could cause damage to the unit.

• Periodically clean the filter located inside the ventilation panel on the unit's front panel. If the filter becomes clogged, heat will become trapped inside the enclosure.

• Install the unit in locations where the temperature is between –10°C and +40°C (14°F and 104°F) and the moisture is less than 90%RH (no dew condensation must be formed).

• To clean, be sure to first switch off the unit's power, then wipe with a dry cloth. When the unit gets very dirty, use a cloth damped in a neutral cleanser. Never use benzene, thinner, alcohol, or chemically-treated cleaning cloth because such volatile liquids could deform or discolor the unit.

6. INSTALLATION PRECAUTIONS

• When mounting the unit in an equipment rack, the inside of the rack must be sufficiently ventilated. To achieve sufficient ventilation, remove all panels on the rear of the rack.

• When mounting the unit in the rack, also mount a Perforated Panel larger than 1U in size*:

(1) at the top and the bottom of the rack, and (2) above and below every 5 units.

* 1U size = 44.5 mm or 1.75" (reference size)

Rack mounting screws are not supplied with the unit. Be sure to use the screws with a diameter of over 5 mm (0.2") and length of over 12 mm (0.47") to mount the unit. Failure to do so may cause personal injury.
