Note: The BASX A-300, BASX A-500, and BASX A-700 have identical features and controls, and
differ only in the power and number of amplifier channels they provide. The BASX A-500 is
shown here for illustration.
1. Trigger Input and Trigger Output
The BASX power amplifier is switched On (from Standby) when a trigger signal is presented at
the Trigger Input; the BASX power amp returns to Standby when the trigger signal is removed.
When the BASX power amp is on, a 12 VDC signal is sent from the Trigger Output to control other
devices.
2. Status LEDs Switch
Disables the front panel status LEDs when set to Off.
3. Unbalanced Inputs
The BASX power amplifier has independent unbalanced inputs for each channel.
Note: Even though we’ve labelled the channels, all of the channels on the BASX power amp are
the same, so you don’t have to use the channels as labelled if you prefer not to.
4. AC Power Voltage LEDs
The BASX power amps are designed to operate on either 115 VAC or 230 VAC, and automatically
detect and configure themselves to operate with your local line voltage. These LEDs tell you
which line voltage the BASX amplifier has detected.
