There are two recommended methods for connecting speaker cables to your amplifier. A high-quality spade lug or hook lug, soldered to the cable (or crimped with extremely high pressure), is best.

Spade lug

Hook lug

Connect a + (positive or red) output post of the amplifier to the + (positive or red) input terminal of the appropriate loudspeaker. [If biwiring, repeat using the other + (positive or red) output post of the amplifier and the + (positive or red) input terminal of the loudspeaker.]

Connect a – (negative or black) output post of the amplifier to the

–(negative or black) input terminal of the appropriate loud- speaker.

Caution!

DO NOT OVERTIGHTEN the binding posts on your

20

amplifier! The unique design of these posts gives far

more leverage than traditional posts. You will achieve

 

tight, high contact pressure connections with only

 

modest finger-tightening, and without having to resort

 

to special tools.

DO NOT FORCE the “wings” up and over a bent or oversized connector, as this may damage the binding post. If your connectors obstruct the turning of the “wings,” slide them into place when the binding post opening is a snug fit; then apply a final quarter-turn as needed to tighten the connection.

2External IR Input

The Nº383 incorporates an infrared repeater input to facilitate a wide range of installation options. If desired, the Nº383 may be placed inside a cabinet or outside the normal line-of-sight in the listening area, with the controlling IR signal being relayed to the Nº383 by any of a number of commercially-available IR repeaters.

The specifications for this ir input call for a triggering voltage of 5 volts at no more than 100 milliamps of current, with the tip of the 1⁄8" mini-plug having positive polarity, as below:
