AMPLIFIERS
- FACTS AND TIPS |
|
- Amplifier
designs vary ; read the manual to ensure you don’t cause damage
by incorrect connections.
- Stereo
mode ; the amp operates as 2 independent mono amps with separate inputs,
outputs and levels
- Parallel
mode ; the amp operates as a pair of mono amps with shared input. Usually
the levels are still independent
- Bridge
mode ; both sides of the amp operate together as a single, larger mono
amp with only one input and one output.
- Ground
lift ; in the event of a hum, (caused by the earth connections of different
parts of your rig being at slightly different voltages, caused by poor
wiring or maintenance in many buildings) the ground lift switch may
reduce this by breaking the signal earth. Note that this does NOT affect
the safety earth.
