4. FUNCTIONS OvERvIEw (FRONT PANEL)
LEvEL LEFT (1) – This controls the volume level of the left channel. In Bridge mode this is the master level.
LEvEL RIghT (2) – This controls the volume level of the right channel. In Bridge mode this is disabled.
CLIP (3) (4) – The Clip LED allows you to set the optimal gain level of your signal so that you can avoid degradation of your signal quality. To find the optimal level, back off the MB 1000 power amp level
so that the LED rarely turns on.
ALARM (5) (6) – The Alarm LED signals failure or protection of the power module. The automatic short circuit protection detects problems and shuts down the
amplifier before any internal damage can be done.
LIMITER (7) (8) – This switch allows you to turn the limiter for each channel on and off.
BRIDgE (9) - This switch allows you to choose the BRIDGE mode, in which the MB 1000 power amp operates as a mono unit with 1000W @ 8 ohms (Channel 2 becomes inoperable when the Bridge
mode is on). In the “bridged” position the LED will be “ON”. In “OFF” position the unit operates as a normal stereo amplifier with 500 watts @ 4 ohms (or 300W/channel @ 8 ohms) per channel or side.
ON/OFF (10) – This switch powers up the MB 1000 power amp; a LED on the right indicates that the unit is on.
