ADORN On-wall System Requirements
Low Impedance Systems
The ADORN A40 and A55 are designed to be used in a low impedance system.
The selector switch is located on the rear of the speaker on wall-mount models A40T and A55T and is on the baffle behind the grill on the
ceiling and pendant products. A conventional power amplifier or mixer-amplifier designed for use with low impedance loads must be used.
We recommend an amplifier that can deliver the full peak power rating without risk of clipping to ensure the best possible performance and
to avoid damage. The Martin Audio VIA amplifier range are a good match for the ADORN series. Performance can be further maintained
by using a good quality system processor to introduce a system protection limiter. The Martin Audio DX0.5 is recommended for use with
the ADORN series.
70v and 100v Line Systems
An amplifier designed for driving distributed line system must be used. The appropriate tap must be selected using the rotary switch,
located on the back of A40T and A55T.
Ensure that the sum of all speaker taps does not exceed the amplifier’s rated power output.
A40T
70v: 20w / 10w / 5w / 2.5w
100v: 20w / 10w / 5w / n/a
A55T
70v: 30w / 15w / 7.5w / 3.75w
100v: 30w / 15w / 7.5w
Connections
Connections are made to all ADORN on-wall speakers using simple spring-loaded push terminals.
Strip approximately 10mm of insulation from the ends of your speaker cables, twist stranded cable or use crimped bootlace ferrule on the
ends. Depress the push lever, insert the cables into the hole and release the lever. Positive, (+) connections should be made to the red
terminal, Negative, (-) connections should go to the black terminal. If “daisy-chaining” connections to several speakers, either twist two
wires together prior to inserting in the terminal or insert two wires together.
