CONNECTING SPEAKERS TO THE A 23

 

 

Speaker Terminals

The five-way binding post speaker terminals on the A 23 accept most speaker wire terminations including single or dual banana plugs, 1/4” spade lugs, or bare wire. Refer to Bare Wire Speaker Termination in the Technically Speaking section for information about bare wire termination.

What You’ll Need:

•Two lengths of speaker wire AWG 16 or thicker with banana plugs, spade lugs, or bare wire

•Loudspeakers or a speaker selector box

YOU SHOULD KNOW

Correct Speaker Polarity is Important

Polarity refers to + and – connections. Speaker wires are coded with printing or a ridge on the insulation on one of the leads so you know which lead was connected to the + and – terminals at the other end. This coding will help you keep the + and - polarity consistent for both channels.

Speaker Wire Length and Gauge (thickness)

When selecting speaker wire, follow these guidelines:

•Keep the length of your speaker wire as short as possible

•Use the thickest wire practical. For lengths greater than 50 feet, use speaker wire with an AWG (gauge) of 14 or lower. The smaller the AWG, the thicker the wire.

•Do not use speaker wire that is thinner than 16 AWG.

•Keep wire lengths for both channels as close to equal as possible.
