AUTO POWER DOWN (APD)
This unit has an Auto Power Down function. The product will
automatically switch to standby mode after inactivity of 20
minutes.
DISABLING THE AUTO POWER DOWN
If you wish to disable the APD function, then press and hold
the power button for 5 seconds when in standby. This can then
be reset to factory defaults by plugging in the mains lead with
the standby button held down.

1. STANDBY/ON
Switches the unit between Standby mode (indicated by dim
LED) and On (indicated by bright LED). Standby mode is a low
power mode where the power consumption is less than 0.5
Watts.
The following functions are for Duo only
2. CARTRIDGE TYPE SELECTOR SWITCH
Match this switch to the cartridge type that your turntable
uses. MM for a moving magnet cartridge or MC for a moving
coil cartridge.
3. HEADPHONE VOLUME
4. HEADPHONES
Allows for the connection of stereo headphones with a ¼” Jack
plug. Headphones with an impedance of between 32 and 600
ohms are recommended.

1. AC POWER SOCKET
2. OUTPUT SOCKETS
Use phono cables to connect to any line level input on your
amplier, such as Aux. NB. Do not connect to a phono input.
3. BALANCE
This control allows you to make ne adjustments to the
relative output levels of the left and right channels. In the
central position the output from each channel is equal.
4. MM INPUT SOCKETS
If your turntable uses a moving magnet cartridge, connect
outputs here (3-5mV, with 47k ohm, 100pF loading).
5. TURNTABLE GROUND
If your turntable has a separate grounding lead then connect
here. This provides shielding to the arm and the sensitive
circuitry in the turntable.
6. MC INPUT SOCKETS (DUO ONLY)
If your turntable uses a moving coil cartridge, connect outputs
here (0.3-1mV, with 100 ohm, 100pF loading).

Troubleshooting
THERE IS NO POWER
Ensure the AC power cord is connected securely.
Ensure the plug is fully inserted into the wall socket and is
switched on.
Check fuse in the mains plug or adaptor.
THERE IS NO SOUND
Make sure the unit is not in Standby mode.
Check that source component is properly connected.
Check that your speakers are properly connected.
Ensure correct cartridge type has been selected (MM or MC).
THERE IS NO SOUND ON ONE
CHANNEL
Check speaker connections.
Check interconnects.
THERE IS A LOUD BUZZ OR HUM
Check turntable or tone arm for ground and connection lead
fault.
Ensure no interconnects are loose or defective.
Ensure that your turntable is not too close to the amplier.
THERE IS WEAK BASS OR DIFFUSED
STEREO IMAGING
Ensure that speakers are not wired out of phase.
VOLUME IS TOO LOUD/QUIET
Check cartridge type matches input type. If a MC cartridge is
connected through the MM inputs, volume will be very quiet
(and vice versa). Note that it is possible to obtain high level
MC cartridges which are designed for an MM input.
