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, aluminumpolyester
shield, 100 percent shield coverage,
conductor to conductor (111 pF per meter).
4. All shields must be connected to the chassis of
the CP750 or DSP100/DSS200 rather than to
circuit (audio) ground. This achieves the RF
interference immunity required by European EMC
standards. For D-connectors, a metal housing
must be used and the shields must be connected
