Panasonic RAMSA WP-1400 - Manual (Page 5)

4. Protect Indicator [PROTECT (orange) B]
The LED indicates that the muting circuit for the B
channel is activated and therefore sound cannot be
produced at the output. This occurs for 4 to 6
seconds when the amplifier is turned on, and also
during overheating or any malfunction that may cause
damage to the speakers.
5. Power ON indicator [POWER] (red)
Indicates that the amplifier is turned on.
6. Protect Indicator [PROTECT (orange) A]
The LED indicates that the muting circuit for the A
channel is activated and therefore sound cannot be
produced at the output. This occurs for 4 to 6
seconds when the amplifier is turned on, and also
during overheating or any malfunction that may cause
damage to the speakers.
7. Mode selector [MODE]
[STEREO A .B , BRIDGE A ONLY]
Selects between STEREO mode (A in/A out, B in/B
out) or BRIDGE mode (A in/A & B combined out). When
using Bridge Mode the input signal must be applied to
the A Channel only.
8. Input level control [INPUT LEVEL B]
• When this control is at "10", the B channel will
reach its rated power output when the input signal
is at a level of + 4 dB.
• The calibrated markings on the front panel indicate
the amount of attenuation applied to the input
signal. The allows proper volume setting of the
speakers when the input signal source is at its
rated level,
9. Output terminals
[OUTPUT MAX LOAD 400W/4il PER CHANNEL]
■ WP-1200
• 8 ohms ................................... 120W + 120W (RMS)
• 4 ohms ..................................... 200W + 200W (RMS)
• Bridge (8 ohms) ................................... 400W (RMS)
• When using in bridge mode, the + side of the A CH
output terminals becomes the hot side, and the +
side of the B CH output terminal becomes the cold.
■ WP-1400
• 8 ohms ..................................... 240W + 240W (RMS)
• 4 ohms ..................................... 400W + 400W (RMS)
• Bridge (8 ohms) ....................................... 800W (RMS)
• When using in bridge mode, the + side of the A CH
output terminals becomes the hot side, and the +
side of the B CH output terminal becomes the cold.
CAUTIONS :
• Do not connect the output channels in parallel.
• When using bridge connection, always use
minimum 8 ohm speakers. Never connect the
speakers between + and — of A CH, or + and
- of B CH.
10. Ground terminal [GND]
An external amplifier ground terminal.
11, AC Power cord
120V AC 60 Hz - approx. 6.5 feet.
12. Rear panel protection angle
These angles protect the input and output terminals
against damage. However, do not stand the power
amplifier on them during performance.
13. Input level control [INPUT LEVEL A]
• When this control is at “10", the A channel will
reach its rated power output when the input signal
is at a level of + 4 dB, Use this control when running
the amplifier in BRIDGE mode.
• The calibrated markings on the front panel indicate
the amount of attenuation applied to the input
signal. The allows proper volume setting of the
speakers when the input signal source is at its
rated level.
14. Input connectors [INPUT A, B +4 dB, 40 kHj
• Two types of input connectors are provided :
XLR-type connectors (female) and 1/4“ tip­
ring-sleeve phone jack.
• These input connectors are connected in parallel
internally. Do not connect more than one input
signal to these connectors at the same time.
• When using amplifier in bridge mono mode,
connect the input signal to A channel only. Any
signal connected to B channel will not be passed.
