The MP Series power ampliers feature a continuously
variable speed fan for optimum cooling. The airow
generated by the fan ows over the copper plated
heatsink resulting in efcient heat dissipation, keeping the
output devices evenly cooled.
The MP Series ampliers also feature sophisticated
protection circuitry. When engaged, the thermal
overload protection mutes the input signal when unsafe
operating temperatures are detected. The short circuit
protection keeps the output devices operating within
safe parameters when short circuits are detected and
the ampliers also feature “Soft Start Protection” to
protect speakers from unwanted ‘pops’ when power is
switched on or off.
The MP Series ampliers feature the option of binding
posts or Speakon™ output connectors.Input connections
are made via 1/4” (6.3mm) TRS, balanced phone jacks as
well as balanced XLR connectors.
Comprehensive front panel LED indicators for
performance monitoring include POWER, PROTECT
and BRIDGE as well as PEAK level indicators for Channel
A and Channel B. The channel gain control knobs and
power switch are situated on the front panel for easy
access.
