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 and understand the safety symbols and messages so you are thoroughly aware of the potential safety

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.

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 high voltage is applied to the speaker terminals, never touch these terminals to avoid electric shock.

Be sure to ground to the safety ground (earth) terminal to avoid electric shock. Never ground to a gas pipe as a catastrophic disaster may result.

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 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 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.

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, causing personal injury and/or property damage.

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.

3

ATTENTION2.

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 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 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 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.

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

3. GENERAL DESCRIPTION

This series two-channel pre-amplifier with the latest styles to meet the needs of small and medium

sized public address system.Two-channel pre-amplifier has 2 inputs at the same time,cac enhance the

audio signal simutenously . Two-channel audio pre-amplifier is the connector of all audiou sources

(including common sources such as CD drive, modem, sound recording deck , MP3 players , special

audio alarm and a variety of microphones ) and the power amplifier devices.The volume of each input

source can be adjusted independently,with priority ranking function,which can require the input source

to prioritize. Two-channel pre-amplifier has sound quality control functions,such as through its ring

tone control circuit or other control circuit, to regulate and control the frequency characteristics of

signals,to play modified and beautifythe sound, and meet the requirementsof the listener's preferences.

4. FEATURES

Standard chassis design, 1U aluminium alloy; light equipment, simple operation, artistic and

practical

Each input independent volume and treble /bass volume adjustment

MIC 1-2 balanced microphone inputs with +48 phantom power switch and gain adjustment

With alarm generator, to provide for the paging tone

LINE 1-4 line input with gain adjustment

REC has a left and right channel audio input and balance left and right channels output control

Note:

When using the microphone input, you must first volume to mid-range position, to avoid sending the
