Connections
INPUT Terminals
The MH-1063 and MH-1075 have barrier strip screw terminals that accept up to #10 AWG (5.3mm2) stranded loudspeaker wire. Observe proper polarity. 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-1063 / MH-1075! 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 sig- nal 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-1063 / MH-1075 to the lower set of input terminals 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-1063 /MH-1075 mode switch is set to BI-AMP. Active crossovers are used before amplification. The mid-high assembly pro- vides a passive crossover between the mid and high frequency drivers.
