Front Panel Controls
Level: Two front-panel, black rotary level controls,
one for each channel.
Power: Front-panel switch; on when in the UP
position.
Back Panel Controls
Circuit Breaker: Provides overload protection.
Front Panel Indicators
Clip: Two front-panel red LEDs, one for each chan-
nel, illuminate when the channel’s output signal is
being overdriven.
Power: Green front-panel LED indicates amplifier
has been turned on and AC power is available.
Fault: Yellow front-panel LED illuminates when
amplifier is in protect mode. Also illuminates briefly
during normal power-up when amplifier is first
switched on.
Input Connectors
One per channel; back-panel three-pin female XLR
input connectors.
Output Connectors
Two 4-pole Speakon connectors (one per chan-
nel) and one pair of back-panel, 5-way binding
posts per channel; accepts banana plugs, spade
lugs or bare wire. (European models do not
accept banana plugs).
Protection
XLS Series amplifiers provide extensive protection
including output current limiting, DC protection,
circuit breaker, and special thermal protection for
the unit’s transformers.
Cooling
Flow-through ventilation from front to back.
Internal heat sinks with forced-air cooling for rapid,
uniform heat dissipation.
