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.
To set up the A1 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.
