off.
3. Zone Power LED
A red LED indicates, when lit, that the corresponding zone is on.
4. Recessed Zone Label Holders
A recessed rectangle for placement of a name label (not included) for each
zone.
5. Local Source Inputs
Stereo RCA inputs for audio from up to four independent audio sources. (Ex.
Receiver, cable box, satellite radio etc).
6. Source Input Trim Adjustment
The Trim Control dials are used to equalize signal levels of each input source
to ensure that switching between inputs will result in the same output level.
7. Remote Source Inputs
RJ-45 jacks for connection of up to four RTI remote source wall plates
(model RSP-1) for independent audio sources located remotely (iPod
®
dock,
CD player, PC etc). RSP-1 wall plates are installed in locations where the
audio source devices will be used (kitchen, ofce etc) and wired back to the
AD-4x with Cat-5 cable. This provides a convenient audio signal path from
the audio source to the AD-4x, in addition to IR control of the source from
an RTI control system.
8. PREOUT Outputs
Provides line level audio outputs for driving external ampliers, such as the
RTI CP-450 or CP-1650 ampliers. The output level is variable and will ramp
up and down with the corresponding AD-4x zone volume control.
