Phones Output
Into this jack you can plug in a 6,3mm headphone. The impedance of the
headphones should not be less than 32 ohms.

LED PEAK
These LEDs illuminate when the amplifier is overdriven and distorted signals are
output to the speakers. Momentary flash of these LEDs can be tolerated, but if these
LEDs should light up more often, so you should reduce the volume to protect both,
your speakers and the amplifier.

LED OFFSET
When this LED is lit, the amplifiers output is a harmful direct current (DC offset).
Epilogue then instantly disconnects the speaker from the amplifier to prevent damage
to the speakers. In general, such an offset occurs at a defect in the final output stage,
ie you should have to check the amplifier at the service.

LED TEMP
When this LED is lit, the permissible temperature of the output stage heat sink is
exceeded.
Epilog
switches the speaker off and LED (

control. Once the heat sink has cooled down to a few degrees Celsius below the
allowable temperature, the speakers are switched back on and the LEDs (

LED MONO
This LED lights up when the monaural playback mode is turned on. This can be done
by holding down the button (

the remote control. A further press of this button triggers the mono sound and LED

LED HF
The frequency bandwidth of Epilog is very wide. Therefore, under certain
circumstances the output stages can start oscillating. A not perfectly matched
combination of speaker cable, crossover and loudspeaker chassis can form a
resonant circuit which, in conjunction with a broadband amplifier, can built an
oscillator. As these high frequencies are mostly beyond the threshold of human
hearing, but overloads unnecessarily the amplifier and the tweeter of the
loudspeaker, the speaker relay is switched off at such high frequencies. LED (
