Packing

The bottom of the flight case in which the unit is packed is NOT symmetrical. If you want to
pack the unit into the case please take care of correct positioning. The distances between the
holes and the edges of the case differ by 5 mm. In case of doubt please measure the distances
and position the unit as described in the sketch below.

NOTE: if the unit is not positioned in the correct direction the cover will not fit exactly. In this
case turn the unit by 180 degrees.

Removing the cover plate

The cover plate is screwed from the bottom side of the unit. To open it, put the unit to the edge of a
desk (right up, NOT upside down!) so that you can access the marked holes in the bottom. Insert a
long (at least 25 cm) 3 mm Inbus-driver and unscrew the four screws. The screws will then fall out.

After that insert a long stick (about 3mm diametre) into one of the holes in the bottom and lift the cover
plate by pushing the stick against it.

CAUTION: when mounting the cover plate again do not tighten the screws using too much
force. Oherways you might have difficulties whith unscrewing later on.

Changing fuses

CAUTION: Before opening the cover plate
and changing fuses the unit must be
disconnected from mains.

If the unit doesn't react when switched on, one
or more fuses might be blown. In this case
address to your dealer or a qualified repair
service. Show this manual to the repairing
technician in order to make him know how to
change the fuses.

When the cover plate is removed (see above),
you can localize the fuses on the processor
pcb according to the sketch right beside. The
fuses are all 20 mm glass types.

Blown fuses must be exchanged by types
of the same current handling capacity (for
115 Volt-versions use the values in
parentheses).

We strongly recommend the use of slow
blow types.

1. Technical Specialties of the OVATION MA8.2 in short

The OVATION MA8.2 delivers nearly any desired power level even into critical loudspeakers without
loss of control. Far over 1000 Watts into 4 Ohms are surely sufficient for reproduction of any kind of
music even when listening at original sound levels. Nevertheless this amplifier can also play at
moderate levels without loosing precision or missing even finest details.

The OVATION MA8.2 has been developed to satisfy even highest demands on reproduction of music.
Forget about noise and distortion and enjoy it's warm and powerful music reproduction - regardless
which loudspeaker You use. It's excellent musical quality comes together with a very worthy finish:
The case is totally made of aluminum

The power supply consists of two toroidal power transformers (2 x 1000VA) with extremely low stray
fields. The energy for the power amplifiers is bffered by two 200.000 µF Capacitor banks. The power
amplifier itself is a balanced construction. That means two amplifiers in bridge connection. Each of the
power amps has it's own transformers and capacitor bank. The amplifiers use 24 output-FETs each
and thus are able to deliver over 180 amperes - if needed.

The input circuitry is also a balanced construction and offers RCA-Cinch
and as well balanced XLR (Neutrik) inputs.

The speaker terminals are naturally in bi-wiring configuration.

Besides that a brilliant blue VF display informs the listener about the actual power (power bar) and the
peak power (numeric). It is also useful to make settings via the intuitive menu system: Configuring the
display (power bar & value display, peak power only and display off), setting the display brightness,
setting the operating mode (permanent, trigger, auto, remote from preamp) and setting the actual
speaker impedance (8, 4, 2 Ohms).
