1. SAFETY PRECAUTIONS

Be sure to read the instructions in this section carefully before use.

Make sure to observe the instructions in this manual as the conventions of safety symbols and messages regarded as very important precautions are included.

We also recommend you keep this instruction manual handy for future reference.

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 so you are thoroughly aware of the potential safety hazards as well as understand the safety symbols and messages.

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 proper damage.

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 replace the unit's terminal cover after connection completion. Because the voltage of up to 100 V is applied to the 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.

Install the unit only in a location that can structurally support the weight of the unit and the mounting bracket. Doing otherwise may result in the unit falling down and causing personal injury and/or property damage.

When the Unit is in Use

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.

Do not insert nor drop metallic objects or flammable materials in the ventilation slots of the unit's cover, as this may result in fire or electric shock.

Do not touch a plug during thunder and lightning, as this may result in electric shock.

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.)

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.

When moving the unit, be sure to remove its power supply cord from the wall outlet. Moving the unit with the power cord connected to the outlet may cause damage to the power cord, resulting in fire or electric shock. When removing the power cord, be sure to hold its plug to pull.

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.

When unpacking or moving the unit, be sure to handle the unit with two or more persons. Falling or dropping the unit may cause personal injury and/or property damage.

RISK OF ELECTRIC SHOCK

DO NOT OPEN

TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT REMOVE COVER. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED

SERVICE PERSONNEL.

When the Unit is in Use

Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.

Make sure that the volume control is 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 speaker 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. A fire or electric shock may result.

The lighting flash with arrowhead within a triangle is intended to tell the user that parts inside the product are a risk of electric shock to persons.

The exclamation point within a triangle is intended to tell the user that important operating and servicing instructions are in the papers with the appliance.

2. GENERAL DESCRIPTION

TOA's IP series dual power amplifiers feature high durability, high quality sound and high output power (IP300D: 300 W, IP-450D: 450 W, IP-600D: 600 W - when a 4 load connected). Input/output levels and other functions can be remotely controlled from external equipment. (An interface unit is required. For details, contact your TOA dealer.) The amplifier is ideal for use in store sound systems, permanently-installed sound systems, and other sound systems.

3. FEATURES

Small in size (2-rack unit size) and light in weight.

Variable forced-air cooling system changes the speed of a fan as the heat sink temperature varies, keeping fan operation noise low.

The input is an electrically-balanced input, which can be converted into a transformer-balanced input using an optional input transformer.

Three different output modes are made available for selection: Stereo, BTL and parallel outputs. In parallel mode, the input level of each channel can be set independently.

An internal limiter limits the current during overload, and a protection circuit disconnects the output during an output short circuit by detecting the levels of both voltage and current. The protection circuit also disconnects the output during an abnormal temperature rise.

Large output screw terminals (10 mm in width) allow connection of solderless terminals with diameter of 9.5 mm. Because two of each of positive (+) and negative (-) terminals are provided, even the four-core speaker cables can be connected.

Control I/O terminal. Input and output levels can be remotely controlled or monitored from external equipment. (An interface unit is required. For details, contact your TOA dealer.)

Detachable carrying handles even after the unit is installed in a rack.

A push-lock level control and its cover prevent accidental setting changes after installation.

An AC inlet simplifies the system maintenance after installation.

4. HANDLING PRECAUTIONS

Line Source: 120 VAC ± 10%, 60 Hz

Never connect the AC power cord to any other line voltage than that specifically designated.

To avoid oscillation, keep the input cable away from the output cable. Particular care must be exercised when mounting the unit in an equipment rack.

In some installations, a ground loop is formed and such noise as hum may be generated. In such cases, cut the loop by removing a shorting metal piece attached to the ground terminals on the rear panel. The noise can be reduced.

These power amplifiers have a filter in their front panel. Clean the filter as frequently as possible. If it becomes clogged, heat cannot escape from the inside of the unit.

Never connect two amplifier outputs in parallel under any circumstances.
