ROKSAN K3 POWER AMPLIFIER
MANUAL
MULTI-AMPING THE LOUDSPEAKERS
If the Loudspeakers utilise more than one drive unit with individual input terminals, for example
a Tweeter and a Woofer, then the loudspeaker performance will greatly benefi t from bi-amping.
Dedicating one amplifi er to the Tweeter and another to the Woofer isolates them from each
other hence reducing distortion and increasing reserved power, creating more headroom and
drive. Speakers work far better with most amplifi ers when multi-amped than using one yet more
powerful amplifi er. NOTE: Drive unit links MUST be removed from the rear terminals of the
loudspeaker before multi-amping.
Please refer to the front and rear panel views
Switching On
The Mains power switch (1) is on the front left underside of the K3 Stereo Power Amplifi er. This
switch should be left ON for normal operation. If unattended for a long period, the Mains power
should be switched OFF and the lead disconnected from the power supply.
When switched, your K3 Stereo Power Amplifi er will go to 'Sleep/Warm-up' mode and the
MODE indicator light (2) on the front will glow GREEN. The amplifi er is now ready for use.
1. If there is no signal (or the signal level is extremely low) the MODE indicator light will stay
GREEN and the amplifier will be in warm-up mode. The exception to this is the initial start
up, if the unit has been off for a long period of time.
2. When there is signal, the input sensor will 'wake up' the amplifi er and the MODE indicator
light will change to RED.
3. After approximately 5 seconds (Allowing the signal to settle down) the Output Relays will turn
on and the amplifi er will be fully operational.
4. If there is still no signal after approximately 30 minutes, the amplifi er will revert to Sleep/
Warm-up mode and the MODE indicator light will glow GREEN.
5. As soon as there is a signal the K3 Power Amplifi er will 'wake up', the MODE indicator light
will glow RED and after approximately 5 seconds the outputs will be activated again.
