5.7 Combo Input Jack
The combination 1/4" TRS and XLR jack (pin 2
hot) is wired in parallel to the Euroblock input.
Do not float the TRS ring or XLR pin 3, connect
it to (-) signal or to ground (if unbalanced).
5.8 Speaker Output Connectors
7.62mm Euroblock connectors are used for
convenient and secure wiring to speaker
loads. Bridge mode uses the center two pins as
indicated on the amplifier back panel.

Always use the AC cord provided by Ashly
for connecting to mains power. The amplifier
auto-detects mains voltage from 100VAC to
240VAC. WARNING: Do not remove or lift the
mains connector ground.
