Troubleshooting

• Turn power on, plug in power cord.
• Verify that there is an input signal from the source. The audio input indicator should
be green (or yellow).
• Verify that there is an output signal. The audio output signal indicator should be
green (or yellow).
• If there is an input signal (indicator green) and no output signal (indicators off), the
ESP-88 may be muted, output levels may be down, or the unit may be completely
unprogrammed. Run ControlSpace
and verify. Signals should be passing from inputs to outputs.
• Verify that the audio input indicator is green. If it is off, increase the source
output or use the Designer software to increase the input gain.
• If the audio input indicator is green and the audio output signal indicator is green,
verify there is enough gain in the amplifier.
• Verify that the audio input signal indicators are not solid red or flashing red.
If they are, reduce the source output level or use the Designer software to
reduce the input gain.
• Verify that the audio output signal indicators are not solid red or flashing red.
If they are, and the input indicators are green, use the Designer software to
reduce the output gain or any intermediary gain in the signal path.
• If the input source signal is clean when it enters the ESP system, and the input and
output indicators are green, verify that the loudspeakers are not being overdriven
and are not damaged.
• Verify that the correct EQ and/or crossover is used in the signal path.
• Power is off or netlist is not loaded. Use ControlSpace Designer software to load a
netlist/configuration
• Verify that the ESP LAN port is connected to a PC with a crossover cable.
• Verify that the Ethernet LAN connection on the PC is enabled. If it is not enabled,
the Link LED on the PC will probably be off.
• If connected to a hub or switch, check that device's Link LED.
• If connected to a hub or switch, verify the ESP and PC are connected with straight-
through cables to the hub or switch.
• Verify that the LAN settings on the Ethernet device you are using on the PC are
set correctly:
- Internet Protocol (TCP/IP) is installed as a protocol on this device
- IP address is set to 192.168.0.88
- Subnet mask is set to 255.255.255.0
• Verify that there is not another LAN connection enabled.
• Verify that there is not another ESP connected with the same address. If unsure,
disconnect one, scan for the remaining unit, and change its address. Repeat with
the second unit.
