The outputs are configured as following for the STEREO and PARALLEL amplifier
modes:
(*) Although it is possible to get the output of both channels with the same connector
(Speakon A), it is recommended whenever possible to use one Speakon connector
for each output (Speakon A for CHA, Speakon B for CHB).
For BRIDGE mode, the following output connection is needed:
Load Capacity:
The HD 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 (
