(servicing) instructions in the literature
accompanying the appliance.
This symbol is intended to alert the user to the
presence of uninsulted "dangerous voltage"
with in the product's enclosure that may be of
sufficient magnitude to constitute a risk of
electric shock to persons.

This is for connecting to the signal output of Power Amplifiers (EPA-2123/2243/2403)
4. CH A SIGNAL OUTPUT JACK
This is for connecting to the signal output of Power Amplifiers (EPA-2123/2243/2403)
5. CH A , CH A/B CONVERT SWITCH
This is a switch for converting Mono or Stereo signal input.
(Mono: CH A, Stereo: CH A/B)
6. CH B SIGNAL INPUT JACK
This is connected to the output signal terminal of Pre-amplifier(EPR-2722) or Mixer
for using Stereo.
7. SIGNAL INPUT LINK JACK
This is for parallel link between CH A signal input Jack and the signal output jack of
Pre-amplifier or Power Amplifier internally and then connected to external output.
8. CH A SIGNAL INPUT JACK
This is connected to the output signal of Pre-amplifier(EPR-2722) or Mixer for stereo.
