FEATURES
• This unit is compuct and will fit into a single rack space .
• The WP-9055 in 2-channel power amplifier prOVIding
continuous outputs of 50 W (RMS) + 50 W (RMS)
(THO 0.05% or l es s for 8D. l oa d 20 Hz to 20 kHz)
employing electronic balanced input c :r ,~ults.
• In bridge mono mode, the power amplifier prOVIdes a
100 W (RMS) outpu . (THO 005% or less , for :6 D.load
20 Hz to 20 kHz)'
• The inpul circuit IS electronically balan ce d employin g
an operaTIonal ampl iii er of exce'lent irClnsien r re sponse
and
Wide bandWidTh. As a result, deterioration of
response caused by the transformer and the effect of
induction 'Wise ;j re minimized
• Two tyPflS of input connectors are provided on each
(I,annel : X til-type connectors (female) and 1/4" TRS
phone jacks
• Output level can be mon itored by LEn's .
• Remote monitor outrl:ts are prOVided on each channel.
These include VL, meter outputs and external access 10
relay contacts allowing cOf)',lIlete indication of operating
status
of amplifier
• The amplifier is protected by a VI-type energy limiter
(voltage/current sensing protection Circuit) that limits
the power supply in the evei'll of a short circuit and cuts
off th e output in the ev e nt 01 overheating or mal·
function.
