WARNING
- Do not open the amp. No user serviceable parts inside the
amplifier.
- Make sure the voltage selector switch on the left
side panel is set properly (115V/230V) before plugging the ampli-
fier on the AC outlet.
- Never use the amp at a high moisture environment or near
liquids.
- The Microtubes 900 can deliver more than 115 db of power.
Exposure to this level of sound can damage your hearing. Use
proper hearing protection if you will be exposed.
- The Microtubes 900 can deliver more than 900 Watts. Be sure
that your speaker cabinet is able to handle that power. You can
reduce the output of the amp by selecting the 2
Ω
mode on the
rear panel (by the Speakon output jack).
- Do not cover the vent holes. The Fan and vent holes are part
of the cooling system of the amp. Covering the vent holes can
produce overheating of the power amp damaging it.
- Do not use an instrument cable as speaker cable. An Instru-
ment cables are not design to deliver power signals going from
the amplifier to the speaker.
