AC Power Connection

Plug in AC mains only after all signal connections have been made and you have verified that both amplifiers are switched off.

We have provided your MONOLITH IIIx CROSSOVER with the proper IEC standard 3-conductor power cords with 3-prong grounding plug. This cord should be firmly inserted into the AC power receptacle located on the rear panel of the crossover, then to any

convenient AC wall outlet. For absolute protection, do not defeat the power plug ground. This provides powerline grounding of the MONOLITH IIIx CROSS- OVER chassis and will protect you from electrical shock.

We do not recommend the replacement or use of "deluxe" or "super" AC power cords. Many of these designs eliminate the ground prong of the male plug and therefore do not follow IEC convention standards. As such, they present the possibility of shock hazard.

Your MONOLITH IIIx CROSSOVER has no power switch as it has been designed to remain on continuously and should remain connected to a continuous AC power source.

Your crossover is wired for the power service supplied in the country of original consumer sale unless manu- factured on special order. The AC power rating applicable to a particular unit is specified both on the packing carton and on the serial number plate attached to the crossover.

Signal Connection

Insert your pre-amps' output cables into the crossovers' INPUT jacks, then connect your low-pass amplifiers' input cables to the crossovers' LOW OUT- PUT jacks, and your high-pass amplifi- ers' input cables to the

HIGH OUTPUT jacks.

Plug in AC mains only after all signal connections have been made and you have verified that both amplifiers are switched off.

Next, connect the speaker leads from the high-pass amplifier to the HI SIGNAL INPUTS on the back of the MONOLITH III. Then connect the low- pass amplifier to the LO SIGNAL INPUTS. Please refer to the pictorial diagram, Figure 4 , at right.
