CONTROLS AND FUNCTIONS
FRONT PANEL
POWER AMPLIFIER FSD-4500E

1.- On/Off switch of the stage.
2.- CLIP: signal peak indicator light for each input. If the indicator light comes on, it is because the input
signal is too high. To solve this problem, reduce the volume of the input signal.
3.- SIG: signal status indicator light. It lights up when a signal is detected at the outputs.

4.- PROT: protection indicator light. It lights up when the temperature protection of the channel is activated.
When the protection is activated, the audio output of that channel is cut off. If this happens, turn off the

equipment, make sure that the air intake and exhaust slots are free of obstacles and lower the volume
of the input signals. Wait a few minutes for the unit to stabilise before switching it on again.

- Green: the stage is on.
- Red: priority input active.

1.- Euroblock connector.
a.- A/D: balanced audio inputs, each input will be played on the output channel named with the same
letter (input A on channel CH A and input B on channel B, etc). If the input signal is unbalanced,
the negative pole (-) will be free.
b.- FAIL: system failure indicator signal to monitor the equipment remotely. This output will remain at
5 V if the operation is normal and 0 V when a fault is detected (disabled/protection/inactive).
c.- DIS: input to enable/disable the stage remotely to make modifications to the wiring without having
to switch off the equipment from the front button. This input is in open circuit (stage enabled), the
circuit must be closed to disable the stage. When the stage is disabled, it is switched off, the LEDs
remain lit and the FAIL signal will go from 5 V to 0 V indicating a system fault.
