When you first power up from the Mains Switch from the front underside of the amplifier, the amplifier goes
into Standby and the MODE Indicator glows GREEN.
In order to reduce power consumption and heat, the power stage of the amplifier is shut down when in
Standby mode.
In normal operation when an external fault such as a short circuit on the loudspeaker leads is detected, the
amplifier will go into standby and the speaker output and AC power relays will disconnect and the MODE
indicator light will glow GREEN. Unless the fault is rectified the amplifier can not be brought out of standby.
If the amplifier output Current exceeds its safe operating range (very low loudspeaker impedance and/or very
high volume level) the protective circuitry of the Kandy will take the amp into Standby mode. If subsequently
the volume is lowered or the loudspeakers changed, the amplifier can be brought out of Standby to resume
normal operation.

If you suspect that your ROKSAN Kandy Integrated Amplifier is not operating properly, you should check all the
connections carefully. Pay particular attention to speaker phasing and channel connections. Phono plugs should
be fully inserted- a frequent cause of problems is that Phono plug surrounds do not make proper contact. Below
are some commonly encountered problems with suggestions for possible cure. The list is not exhaustive: If you
have any unresolved problems, please consult ROKSAN or your appointed ROKSAN dealer or distributor.
