GENERAL

Panasonic's new RAMSA power amplifiers WP-1200,

WP-1400 are high performance for the high density,

powerful, high-quality sound musicians demand. And to

maintain the optimum operating temperature, WP-1200 and

WP-1400 features the newly developed servo cooling

system which is constantly adjusted the fan speed

regardless of output level.

Speaker safety is further assured by CROW-BAR circuitry

which operates when DC voltage is generated at the output

terminals due to amplifier malfunction.

FEATURES

The WP-1200, WP-1400 are 2-channel power

amplifiers providing continuous outputs of 200W (RMS)

+ 200W (RMS) [WP-1200], 400W (RMS) + 400W [RMS]

[WP-1400] (THD 0,3*/. or less with 4-ohm load, 40 Hz to

20 KHz). At 0-Ohm load : 120W (RMS) + 120W (RMS)

[WP-1200], 240W (RMS) + 240W (RMS) [WP-1400]

continuous output (THD 0.3*/. or less with 8-ohm load,

20 Hz to 20 KHz) can be obtained.

In bridge mono mode the power amplifier provides

a 400W (RMS) [WP-1200], 800W (RMS) [WP-1400]

output (THD 0.3*/. or less for 8-ohm load, 20 Hz to 20

KHz).

The input circuit is electronically balanced employing

an operational amplifier of excellent transient response

and wide bandwidth. As a result, deterioration of

response caused by the transformer and the effects

of induction noise are minimized.

Two types of input connectors are provided XLR type

connectors (female) and 1/4” TRS phone jacks.

The amplifier is protected by a Vl-type energy limiter

(voltage/current sensing protection circuit) that limits

the current in the event of a short circuit and cuts off the

output in the event of malfunction such as overheating

or DC.

The muting circuit prevents switching noise caused by

turning the amplifier on or off.

Input level adjustment controls are provided on each

channel.

5 way binding posts are provided as output terminals.

These posts are evenly-spaced, enabling the use of

dual-banana plugs for either individual channel output,

or bridge mode.

A ventilation fan prevents the amplifier from

overheating when properly installed.

These amplifiers are power efficient due to the Class

H power output circuit.

Output terminal CROW-BAR DC detection circuit

protects the speakers.

Front-panel LED's indicate peak signal and protect

mode.

The automatic fan control circuit varies the fan speed

as needed by sensing the temperature of the heat sink

and the power transformer.

PRECAUTIONS

Do not stand the amplifier vertically on its back.

Due to the muting circuit, no sound is produced for 4 to

6 seconds after turning on the power supply.

Always use a power source of adequate capacity.

Do not turn on the power of multiple power amplifiers

at the same time. Never allow the ventilation holes on

the Front and Rear of the amplifier to get obstructed in

any way.

To clean the amplifier, wipe it with a dry cloth. If the

case is very dirty, disconnect the AC cord from the

power source, then wipe it with a cloth dampened in

water or mild soapy water, then wipe dry thoroughly.

Never use solvents or chemical cloth, similarly, never

spray insecticides as they may cause discoloration or

peeling.

If any trouble is found, disconnect the power cord and

contact your dealer.
