Amplifier F91
The amplifier F91 is the version with higher power out-
put (2 x 170 W rms.). Equipped with protection and
watch dog functions described below. The BGM adap-
ter (to attenuate the volume in BGM mode) is integra-
ted. The amplifier is equipped with an automatic
volume control (AVC) to level out different recording
levels.
In 2-channel mode it is possible to control both chan-
nels separately with the IR-remote control.
You can also make selections with the optional infra-
red remote control.
11.1
Verification of power voltage
ATTENTION! Always remove power plug before opening transformer cover plate. Never
attempt any intervention to these parts unless qualified.
The power voltage setting is on the cover plate of the
F91 transformer. Machines for USA are set to 117 V.
Jukeboxes „UNI-Pack“ are shipped in 230 V setting.
This is marked on the machine label inside of the
door. If the voltage setting is not clear the transformer
cover plate has to be removed.
The mains fuse (T3,15 A, res. T8 A for 117V) is loca-
ted near the RH side of the cover plate.
The position of the two plug connectors on the trans-
former terminals 1 to 9 (primary side) indicates the
current voltage setting. The following combinations are possible:
240V = 1 - 9
230V = 1 - 8
220V = 2 - 9
210V = 2 - 8
117V = 1 - 6
100V = 2 - 6
Never connect the fluorescent supply to other
contacts
.
If you intend to change the power voltage to a higher
voltage (e.g. from 117V to 230V) it is recommended to
use a subtransformer for the flourescent lamps or
change the ballast according to the used voltage (e.g.
for 230V).
The power consumption in standby is approx. 146W.
With max. volume it is approx. 540W.
