Power Amplifier OVATION MA8.
Dear Customer, Thank you for the trust you have shown in us with the purchase of this mono power amplifier. You have acquired a versatile hi-fi component with absolutely excellent sound qualities. It is understandable that you would immediately like to start listening to the music. Despite this we advise you to display some patience, you will see that this will stand you in good stead. Before you take this equipment into use for the first time you should thoroughly read this operating manual.
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.
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. Operation of the OVATION MA8.2 In the text you will find a number behind the names of the individual controls.
2.1 Placement of the unit / cooling The OVATION MA8.2 can warm up considerably - depending on the required output power. It is therefore very important that air circulation is possible to both the sides and underside of the unit and that heated air can vent upwards. This will allow good heat dispersion. Locate the unit in such a way, that a minimum of 10 cm free space is maintained around the unit to any other equipment or walls.
2.3 First steps, switching on and off Right after arrival in your home the OVATION MA8.2 might be cold (depending on the weather outside during transport). In this case we recommend that after unpacking and placing it in your room you let it "acclimatize" without mains connection for at least one hour . Connect the power supply socket (10) with a suitable power cord to the mains and set the mains switch (1) to on (push once). The unit performs a self test while the AMP logo scrolls into the display (2).
If you are using banana plugs secure the outer parts of the sockets (by clockwise turning) before inserting the pin. This will prevent rattling. On delivery you may find that plastic plugs cover the 4mm holes of the loudspeaker clips. These can be removed with a thin screwdriver. To be able to fully appreciate the tonal qualities of the mono amp you should place the unit as close as possible to the loudspeaker.
3. Menu system 3.1 Operating the menu system The settings for customizing your OVATION MA8.2 are done via the menu system. The menu system works while the unit is on as well as in stand by mode. To access the menu just press the knob (3c) in the middle under the display (2). The display shows now the SET OPERATING MODE menu. The actual setting has a frame around. The setting can be changed by pressing the knobs (3d, 3e). Changing to other menus is done by pressing the - knobs (3a, 3b).
4. Care of the casing The surface and printed text on the casing is largely scratch resistant. The casing may be cleaned with a mild soap solution or spirit based glass cleaner (use economically) and a soft lint free cloth. NOTE Care should be taken during cleaning to ensure that no liquids can ingress into the casing. It is advised for safety reasons to remove the power cable from the electrical supply before cleaning the casing with a damp cloth. Do not use solvents or abrasives for cleaning.
After switching off the pre-amplifier the amp does not automatically switch to STAND BY (after approx. 5-10 min.) although the "auto" mode is selected. • Check whether a low humming or chirping noise is heard from the loudspeakers after switching off the pre-amplifier. If this is so then scattering emissions within the cable are interfering with the automatic switch-on circuitry. This is interpreting the interference as a music signal and reacts by not switching off the amp.
