Important notice

Safety instructions

voltage in your area meets the voltage requirements printed on the power supply. The power supply is used to disconnect the unit from the mains. Make sure that the power supply is easily accessible at all times. Avoid letting liquids enter the device or the power supply. Never place any item containing liquid, such as a flower vase on or near the device. Never spill any liquid on the device or the power supply. Never place any naked flame sources, such as lighted candles on or near the device. The product shall not

Never handle the device, the power supply while your hands are wet or damp.

Connectors

Make all connections whilst the phono amplifier is disconnected from the power supply. Take care to connect the left and right channels correctly. The right channel is usually marked red, the

left channel black or white. Do not connect the phono amplifiers output to a phono input (sometimes labelled

on the amplifier.

Connecting of record players

Connect left and right channels of the tonearm signal lead to the sockets marked phono amplifier. It is possible to connect 2 record players at once or connect 2 tonearms from a turntable equipped by 2 tonearms. The earthing wire(s) may be connected to the screw terminal if you encounter hum problems when using the record player.

Line level input

Any line level source of signal can be connected to the preamplifier using and then converted to digital data using coaxial S/PDIF output or USB output.

Connect the low voltage plug from the power supply to the connecting the power supply to the mains. The unit can be switched on and off by using 2 different methods which are equal in priorities.

1. Using front pushbutton to switch on or into standby

The pushbutton on the front panel of the unit alternately turns the power on or returns it to standby mode. The blue LED on the front panel shows that the unit is powered on. If a trigger signal is present the unit can’t be switched off by the pushbutton.

2. Remote power on - triggers

The unit can be switched on via other Box Design components when a 12V trigger voltage is present at the

2.5mm socket marked available as accessories. The remote power-on signal can be relayed to further units via the socket. When the 12V trigger signal is switched off, the unit will also switch off.

No signal on one or both channels: No connection between player and phono amplifier or amplifier. This could be due to a faulty plug, broken wire or solder joint or simply loose plug/socket connection.

Strong hum: No earth connection from cartridge or arm, or arm cable to phono amplifier, or earth loop.

Output too quiet or too loud, or distorted: Input gain incorrectly set - input overloading or insufficiently amplified.

Service

Should you encounter a problem which you are not able to alleviate or identify, please contact your dealer for further advice. Only if the problem cannot be resolved there, the unit should be sent to the responsible distributor in your country.
