Indicators:

• Signal: Two or four green LEDs, one for each channel, illuminates when the channel's input signal level is above –40 dBu.
• Clip: Two or four front-panel red LEDs, one for each channel, illuminates when the channel's output signal is being overdriven.
• Power: Yellow front-panel LED indicates amplifier has been turned on and AC power is available.
• AC Mains: Red front-panel LED indicates the presence of AC power at the power cord, even if the amplifier is not turned on.
• Fault: Red front-panel LED illuminates whenamplifier is in protect mode. Also illuminates briefly during normal power-up when amplifier is first switched on.
• Bridge: Yellow LED indicates that amplifier is in bridge mode (Channels 1 and 2, Channels 3 and 4 in Xs4300).
• Temp: Red LED indicates that channel(s) are in thermal protect mode.

Construction:

• Ventilation: Flow-through ventilation from front to back.
