INPUTS Terminals

The MHV-1090 has barrier strip screw terminals that accept up to #10 AWG (5.3mm

) 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 respec-

tive 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 loudspeaker. 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.
