9. Limiter In / Out Button: The Limiter In/ Out button activates a pre-set input limiter, which helps reduce the level of accidental loud
noises and clipping distortion for each Zone(both channels of each Zone).
10. Ch Line Input: These inputs allow connection of sources directly to the individual channels. This input allows Stereo, line-level
source or two separate mono audio sources. If you Bridge the Zone’s pair of amplifiers into an 8-ohm speaker circuit, use the
Left input and connect a mono source.
11. For Bus Input: These RCA connectors and a screw terminal strip are provided to connect your mixer, stereo / preamp, CD
player or other audio media device. (Note: use only one type of source). For Bus outputs: These RCA connectors are simply in
parallel with the Bus Inputs and enable you to interconnect the CA1250 with another CA1250 or amplifier. ( Note: only the Input
Bus signals will be patched to Output).
12. IR remote/ mute/ status port.
13. Speaker Connections: Insert bare wire ends here and tighten the retaining screws to secure properly. For a stereo Zone or dual
mono Zones, connect the + and –system leads from each Zone to one +4 ohm and its adjacent-Neg terminal in the L& R
terminal groupings. In Bridge mode, connect the + and – leads from an 8-ohm speaker circuit (not 4-ohms-see Stereo/ Bridge
Button section above) to each of the +4 ohm terminals.
14. Line/Bus Button: Each Zone’s input source can be selected using this switch. Depress the button to select the audio program
coming from the Bus Input or leave it in the up position to use the Zone’s Line Input.
15. Master control input.
16. Master control output.
17. RS232: The RS232 serial port allows two-way communication control by a home automation system.
