Notes:
1. Follow all local electrical and building codes.
2. Use earthed (grounded) conduit wherever
possible. Avoid routing signal wiring near electric
motors, rectifiers, power wiring, dimmer wiring, or
other sources of electrical noise.
3. For two-conductor with shield wiring, use Belden
8451 two-conductor shielded cable or equivalent:
tinned copper, twisted pair, 22 AWG stranded tinned
copper drain wire, aluminum-polyester shield, 100
percent shield coverage, conductor to conductor
(111 pF per meter).
4. All shields must be connected to the chassis of
the DA20 or DMA8Plus rather than to circuit (audio)
ground. This achieves the RF interference immunity
.
For D-connectors, a metal housing must be used
and the shields must be connected to the housing.
required by the FCC and European EMC standards
5. Re-attach existing cables (Dolby Part No’s 83137
and 83138) to the DMA8Plus as shown. (Cables
included in CDA/200 cable set.) The Shielded Audio
Cable is included in the CDMA/A cable set.
