The outputs are configured as following for the STEREO MODE:
For BRIDGE mode, the following output connection is needed:
Load Capacity: The SM amplifiers have a sufficient current capacity to admit very
low loads (down to 2 Ohms). It should be taken into account that many loudspeakers
using passive filters and whose nominal impedance is of 8 Ohm do in fact present
impedance much lower than the nominal one at certain frequencies. Therefore, it is
advisable to use 2 Ohm loads only when one is perfectly aware of the impedance
curve of the loudspeaker system to be connected. Otherwise, the amplifier could
cause cut-offs at the output due to the short circuit protection (low impedance, <2
Ohm) or over heating.
6 - PRE-AMP CONNECTION
The input (BALANCED INPUTS) enables connection
through XLR-3 connectors. The amplifiers incorporate
balanced input for a high rejection of parasites generated
by long signal cables, proximity to electric wires or sources
causing them
BALANCED Inputs:
1. Shield
2. (+) Live
3. (–) Return
UNBALANCED Inputs:
1. Not connected (* See Note)
2. (+) Live
3. Ground
