Connections
INPUT Terminals
The MH-1075C has barrier strip screw terminals that accept up to #10 AWG (6mm
2
) stranded loudspeaker wire. Observe proper polar-
ity. Use the largest wire size and shortest wire length for the application.
OUTPUT Terminals
The OUTPUT terminals are factory-connected to the 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.
NOTE! Maintain proper loudspeaker connection polarity throughout the entire system for maximum performance. Do not
apply full range signal to the MH
- 1075C! There is a mid - high passive crossover for bi - amp mode only. There is no crossover
connected when operating in tri - amp mode. A protection network is always active. 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.
BI - AMP mode connections - Ensure the mode switch is set to BI - AMP , connect the input to the MH-1075C to the lower set of input ter-
minals marked “ BI - AMP + -”.
BI - AMP Mode - one amplifier
channel is used for the low
frequency cabinet and one
amplifier channel for the
mid-high assembly.
The MH-1075C mode switch
is set to BI-AMP . Active
crossovers are used before
amplification. The mid-high
assembly provides a passive
crossover between the mid
and high frequency drivers.
