1. Placement
Please ensure that there is sufficient ventilation and flow of air on all sides of the amplifier. There must be a minimum space of
10 cm (approx. 4") above the amplifier so that the heat can escape.
Note: Never completely cover or operate the amplifier in a place with insufficient flow of air. If you do, the amplifier may over-
heat.
In case you wish to operate two or more amplifiers never stack them. You may place them on shelves or fit them under a cabinet.
Remember to keep the minimum space of 10 cm (approx. 4") above the amplifier.
Keep the amplifier away from humidity, vibration, excessive dust and direct sunlight. Do not operate the amplifier near other
electric appliances (for instance neon lights and motors).
2. Connecting Power Amplifier(s) to Speakers and Preamplifier
To connect your power amplifier(s) properly to your loudspeakers and your preamplifier please refer to the following descrip-
tions and diagrams.
Attention! The power amplifier works fully balanced, if operated as mono block. The minus-terminals are not connected to
ground. Therefore, never connect any ground-related potentials, as is common with active and semi-active speaker systems
(including active subwoofers).
Advice: Remove all cables from inputs that are not in use.
