Panasonic RAMSA WP-1200

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.
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], 0OOW (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.
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.
Speaker safely is further assured by CROW-BAR circuitry
which operates when DC voltage is generated at the output
terminals due to amplifier malfunction.
• The amplifier is protected by a Vl-lype energy limiter
(volt age/cur rent 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.
• 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.
