Connections
Line input
Eachline input is suitable for connecting to any line level music source. Line level sources include CD
players, radio tuners, televisions etc.Each line input consists of a pair of RCA connectors.The M2 Line
Balanced has 4 line inputs available.
Tape loop
The tape loop is available for connecting to a cassette desk. The 'tape in' connections should be
connected to the cassette deck's 'line out' and the 'tape out' connections should be connected to the
cassette desk's 'line in'. The tape in can be used as an additional line input if required. The RCA
connectors are marked red for the right channel and white for the left channel.
Feedback switches
Two feedback switches are located next to the ground terminal on the rear panal. These are used for
matching the pre-amplifierto the rest of your system. Set the switches to the 'on' position if any of the
following apply, when in doubt, choose the setting that provides the best sonic performance:
• If the volume control is too sensitive.
• If the interconnects between the pre-amplifierand the power amplifier are longer than 3 metres.
• If your amplifier has an input impedance of less than 50 kOhms
NOTE:
Always turn the power off before adjusting the feedback switches. Ensure that both feedback
switches are in the same position.
Balanced output
The balanced outputs are provided to be used with power amplifiers equipped with a balanced input
option. Using the balanced option can sometimes result in a better sound quality, depending on the
exact deign of the power amplifier.
Unbalanced output
There are 2 sets of unbalanced outputs are provided for Bi-amplified systems. Both sets are identical and
may be used for single amplifier operation. The connectors are marked red for the right channel and
white for left channel.
NOTE:
The balanced/unbalanced selection switch must be set to the appropriate position. It is not
recommended to use both the balanced and unbalanced outputs simultaneously.
Mains power connection
Use the supplied cable to connect the IEC inlet socket on the pre-amplifier to the mains supply. Ensure
the power is switched off when you do this.
NOTE:
It is important that all connections are firm, secure and airtight. any oxidisation of the
interconnects will result in loss of performance. Always use high quality interconnects - Audio
