SWITCHING ON
The Mains power switch (14) is located on the rear panel of the amplifier. 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 ON from the rear panel, your Kandy Power Amplifier will go to Operational mode and the MODE
indicator light (1) will glow RED. The amplifier is now ready for use.
1
If there is no signal (or the signal level is very low) the MODE indicator light will change to AMBER after
approximately 2 minutes
2 If there is still no signal after approximately 10 minutes, the amplifier will revert to Standby mode and the
MODE indicator light will glow GREEN
3 As soon as there is a signal the Kandy Power Amplifier will ‘wake up’, the MODE indicator light will glow
RED and after a couple of seconds the outputs will be activated.
USING THE TRIMMERS
Please refer to the rear panel views on page 4.
There are two or
three Trimmers (7, 8 & 9 ) that can be utilised to reduce the gain of any of the channels and
thus reduce the output level on that channel. In this configuration the input signal to that channel must be
connected to its Trimmed Input socket only (not the Straight Input). When connected as such the gain on that
channel can be reduced as indicated below.
NOTE: To avoid damage to the trim pots always use a good quality flat blade electrical trimmer.
NOTE: These values and positions are approximate and should be used as a guide. During the installation and
set-up, you should adjust the trimmer to achieve the desired output level.
