INPUTS Terminals
The MHV-1090 has barrier strip screw terminals that accept up to #10 AWG (5.3mm
2
) stranded loudspeaker wire. Observe proper polarity. Use the
largest wire size and shortest wire length for the application.
OUTPUTS Terminals
The OUTPUT terminals are factory-connected to the high and very high-frequency drivers. These terminals should ONLY be connected to their
respective driver. Do not connect signals to these terminals as all protection and equalization circuitry will be bypassed. They are not for daisy chaining
the signals to other drivers.
NOTE! Maintain proper loudspeaker connection polarity throughout the entire system for maximum performance. Do not apply full
range signal to the MHV-1090! There is a high/very high-frequency passive crossover for tri-amp mode only. There is no crossover
connected when operating in quad-amp mode. All required signal processing must be done before the signal is applied to the loud-
speaker. Do not connect any signal to the upper sets of OUTPUT terminals.
TRI-AMP mode connections- Ensure the mode selector switch is set to TRI-AMP, connect the low-frequency signal to the low-frequency enclosure;
connect the mid-frequency signal to the mid-frequency driver; connect the high/very high-frequency signal to the VHF/HF terminals on the INPUTS ter-
minal strip.
