Using the A1 in other applications
The A1 amplifier can be used as a power amplifier in other system configurations.
The A1 can drive other passive loudspeakers including subwoofers, floor monitors, studio
monitors, and guitar cabinets. The A1 can amplify a balanced or unbalanced signal from a line-
level device, such as a mixing console, and drive any loudspeaker load (4-ohm minimum) that is
capable of handling 250W.
Setting up the A1 for use with other systems:
1.
Make sure the A1 amplifier Power switch is OFF.
2.
Connect a line-level output connector from your source device to the INPUT connector of the
A1 amplifier.
• This could be the line-level output from an electronic crossover, mixing console, electric
bass/electric guitar amplifier head unit, preamp, digital modeler, or studio console line
output.
• You can use either a balanced (TRS) or unbalanced (TS) connection. The amplifier will sense
the type of connection and automatically adjust the overall level.
3.
Connect the OUTPUT of the A1 amplifier to:
• Any 4-ohm loudspeaker load capable of handling at least 250 watts RMS.
• Any 8-ohm loudspeaker load capable of handling at least 125 watts RMS.
4.
If you want to add an additional A1 for more bass, connect the THRU connector of the first A1
to the INPUT connector of another A1 amplifier using a ¼" TRS cable.
5.
Set the A1 power switch to ON (I).
6.
Adjust the source level so that the A1 signal indicator flashes green. At a maximum source
level, the A1 signal indicator occasionally flashes red. If the indicator is constantly red,
reduce the source level.
Note:
Using the A1 amplifier and its connected B1 bass modules with any source device other
than the PS1 power stand is not recommended.
