These amplifiers have sufficient fan cooling capacity built in, and need no extra
external fan cooling to operate normally. Their compact ‘UltraFin’ heatsinks provide
massive surface areas for rapid cooling and stable temperatures.
BUT...
When racking up these amplifiers, you MUST allow space for the air to exit from the
rear
of the amplifier. Remember that Power = Heat, and Maximum air flow =
successful heat management.
The easy way to handle it is to follow the Air Flow diagram above, and have an open
back to the rack. Don’t let anything block the air exit paths - the air must have a way
out.
Things to check before you plug the amplifier in
Main AC power
- check that the voltage on your amplifier is the same as the voltage
at the power point. It is a really good idea to check this
before
plugging the amplifier
into the power point. Be especially careful of plugging into unchecked ‘piggyback’
plugs, power distribution boxes or extension cables.
Your warranty does not cover damage caused by incorrect wiring.
Make sure the amplifier is connected to the same AC power supply and Earth/
Ground as the rest of the system, otherwise you may set up an Ground loop hum.
The AmbiDrive weighs approximately 12 kilos/26 lbs, the MicroDrive 13 kilos/28 lbs,
and the PowerDrive LITE 14 kilos (30 lbs). We
strongly
recommend that you use the
rear mounting slots as well as those on the front panel.
There are 2 cooling fans that circulate air around and through the heatsink.
It is
extremely
important that you ensure that there is
unrestricted
air access to
these fans, and also
unrestricted
air exit path.
Clean the fan filters regularly or at the first sign of becoming clogged.

Input Link Switch
Pressing this switch in makes the same signal appear at both inputs without
having to use a Y lead. Also known as Parallel Mono mode
Aux Input to Sub Channel connector
This balanced jack connector lets you use the Sub channel as an extra full range
channel when a Sub is not required. To use it as a monitor channel, for example,
plug your monitor send output from the console in here, and you can connect up
2 x 8 ohm monitor wedges
