ADORN Ceiling System Requirements

Low Impedance Systems

All models can be used in a low impedance system by selecting the 16Ω position on the rotary switch, located behind the grille. A
conventional power 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

All ceiling and pendant models can be used in a 70v or 100v line system. An amplifier designed for driving distributed line system must
be used. The appropriate tap (please see below) must be selected using the rotary switch located on the front baffle of ceiling and pendant
models.
Ensure that the sum of all speaker taps does not exceed the amplifier's rated power output.
ACS-40TS
70v: 20w / 10w / 5w / 2.5w
100v: 20w / 10w / 5w / n/a
ACS-55T(S) & ACP-55T
70v: 30w / 15w / 7.5w / 3.75w
100v: 30w / 15w / 7.5w

Connections

All models feature a connection cover for safety critical applications, it provides strain relief to the cable connections which helps prevent
accidental disconnection. Strip approximately 10mm of insulation from the ends of your speaker cables, twist stranded cable or use
crimped bootlace ferrules on the ends. Loosen the four screws – this will allow the connection cover to be removed without completely
removing the screws. Pass the cable through the gland from outside to in. The cables connect to the speaker via a ceramic terminal block.
Connections are as follows:
1. +
2. –
3. –
4. +
The positive (+) and negative (–) from your in-coming cable can connect to 1 & 2 and your link-out cable to 3 & 4. Connections to the
ceramic terminal block are loosened and tightened using a cross head screwdriver.
Replace the connector cover ensuring that there is no strain on the connections, tighten the gland to seal the connection.
