4 Pr oduct Overview The PR-4Zi is a four-zone, six-source A/V pr eam- plifier that offers independent control of sour ce, volume, and tone for each zone. In addition to standard pr eamplifier contr ols, the PR-4Zi allows zone settings to be stored and r ecalled. SYS- TEM ON and SYSTEM OFF functions provide sin- gle-button, system-wide on/off contro[...]

W iring Instructions 5 CONNECTING AMPLIFIERS Connect the Zone Output of each PR-4Zi zone to one line input of a multichannel amp. Figure 2 shows a connection to the Russound DP A-6.12 T welve Channel Audio Amplifier . (Figur e 2 also shows a trigger connection, discussed on p. 6.) If using multiple two-channel amplifiers, such as the Russound DP A-[...]

7 W iring Instructions CONNECTING VIDEO MONITORS Each PR-4Zi zone has a composite video output to allow viewing video from any of six A/V sour ces. Connect monitors as shown in Figure 5 using RG6U cable with RCA type connectors. If mor e than two monitors are being used in a zone, a composite video distribution amplifier is r ecommended. The PR- 4Z[...]

W iring Instructions FIXED ZONE LINE OUT: CREA TING SUBZONES The PR-4Zi has six buffered, fixed-level audio/video outputs as shown pr eviously in Figure 1 (p. 4). When set to FIXED ZONE LINE OUT (Figure 7), the last four outputs can be used to cr eate subzones of each main zone. A subzone gets the same source selected for the main zone, and ther ef[...]

14 DSC/DAN KEYP ADS Once the PCK(IR) keypads have been wired, con- nect the DSC keypad’ s 16-pin header to the 16- pin receptacle on the side of the main keypad (see Figure 1a and 1b). Be sur e to keep the cor- r ect pin alignment. If you ar e using a DAN key- pad with the system, connect it to the input r eceptacle on the side of the DSC keypad.[...]

15 IKP-1 INFRARED KEYP AD PROGRAMMER The IKP-1 is a programmer used to simplify and speed up the IR programming for the DAN and DSC IR learning keypads. Learning keypads that can be used with the programmer have a plug located at the front left. Refer to IKP-1 Instruction Manual for complete instructions. Figure 14 – Multiple Progamming with IKP-[...]

16 Peripheral Devices P AGING The PR-4Zi has five paging inputs. The four Zone-Specific P AGE INPUTS allow for paging to all zones except the zone where the page origi- nates. The P AGE ALL input will allow paging to all zones. A page turns on all zones to their r espective pr eset paging volume (see Memory Procedur e, p. 11). All devices trigger e[...]

Peripheral Devices 17 IR EMITTERS The PR-4Zi has seven IR outputs: Source 1–6 and Common. Sour ce 1–6 outputs are sour ce-specific and provide IR signals only to the selected source; the Common out- put provides IR signals to all sources. Source-specific IR outputs (Figur e 17) are useful when a system has two or more of the same model source c[...]

18 Peripheral Devices PRC -1 REMOTE CONTROL The Russound PRC-1 remote contr ol is pr epro- grammed to operate more than 1,000 audio and video components, including the PR-4Zi. Set it up by simply punching in a three-digit code that matches your equipment. The PRC-1 also has the ability to learn new functions, allowing you to customize it and update[...]
