4. 1 Input selection: balanced / unbalanced

The MONO II I– MK 2 has balanced XLR input sockets 5.1 and unbalanced RCA input sockets 5.2. To connect a

preamplifier, please use one of them.

Fig. 2: INPUT SELECTION

In order to connect this amplifier with a separate preamplifier, e.g. the TUBE PREAMP II from ACCUSTIC ARTS

please use interconnect cables with best possible shielding and high quality connectors. This is the only way to

ensure that the sound quality of the power amplifier is fully exploited.

These pin assignments comply with the standard adopted by the Audio Engineering Society. Refer to the operating

manual of your other units to verify that the pin assignments of their connectors correspond to your ACCUSTIC

ARTS

unit.

4. 2 Damping factor linearization

Fig. 4: DAMPING CONTROL ON/OFF

The damping factor linearization can improve the performance of your speaker. By pushing

this button the function is activated (= ON).

4. 2. 1 General information

The damping factor D of a power amplifier is determined from the load resistance R

for the measurement assessment 8 Ω resistance) divided by the internal resistance of the amplifier R

Physical equation: D = R

/ R

D : damping factor (calculated number)

: load resistance (connected loudspeaker, for the measurement assessment 8 Ω resistance) *

: internal resistance of the amplifier (usually measured at 1 kHz) **

Please press the button INPUT SELECTION to use the balanced XLR input

AUDIO INPUT BALANCED or release the button to use the unbalanced

RCA input AUDIO INPUT UNBAL.

You can use either the balanced input or the unbalanced input but not

at the same time.
