Pre-Amp Connection; Start-Up And Operation - Master audio DX Series User Manual

8 - CONNECTION IN PARALLEL MODE
To use PARALLEL mode place the above mentioned
BRIDGE/PARALLEL/STEREO selector switch in PARALLEL
mode.
The corresponding indicator located on the front panel will
light up (PARALLEL).
This mode produces an internal bridge between the two Inputs (CHA and CHB)
without the need of external connecting cables. This option is useful for a Bi-amplified
configuration system.

9 - PRE-AMP CONNECTION

The input enables connection through XLR-3. The
amplifiers incorporate balanced input for a high rejection of
parasites generated by long signal cables or proximity to
electric wires or other sources causing them.
10 – COOLING
The DX Series are equipped with electronically controlled
forced ventilation. The turbines, situated at the rear,
increase their speed according to the temperature or
power delivered by the amplifier. It is very important to
make sure the ventilation holes are unobstructed to enable
the free intake of air and release of hot air.
Intermittent operation of the turbine prolongs its useful life
and prevents the interior cooling ducts from becoming easily blocked.
Depending on the work conditions and installation site, the inside should be cleaned
regularly. This is done by removing the upper lid and alienating any remains of dust
and dirt. It is advisable to entrust this task to an authorized Technical Service.

11 - START-UP AND OPERATION

Once the mains, loudspeaker and sound sources (input) connections have been
made correctly, start up the pre-amp sources and then press the ON/OFF switch.
Turn the volume controls clockwise to obtain the maximum gain. When the maximum
output power has been exceeded (clipping/distortion), this will be indicated by the
corresponding Led.
