6 Designing an Installation Plan If you are a prof essional installer , you ’ll probably want to skip over this section, however if you ar e setting up your system f or the first time this sec tion can help make your installation a little bit easier .
7 Using P assive Speakers If you are using passive (un-po wered) speakers you need to first decide where y ou will place your power amplifier . If the speakers in a par ticular sound zone are less tha.
8 Quick Start W e recommend that you take the time to r ead through this manual, and then, use it as a ref erence guide. If you ar e installing your first system y ou should read through the section “Designing an Installation Plan ” on page 6 before you start connecting your S zone.
9 Note: The MIC TRIM level contr ol allows you to set the best sig- nal to noise level . Very simply put, this means the hottest mic level with the least amount of distortion. If the MIC TRIM is too low , the mic level may not be loud enough. If the MIC TRIM is set too high, the channel will distort.
10 Next connect your line inputs to channels 2 using the wir- ing guide below . These inputs are set to ac cept –10 dBV levels, which is the standard for devic es like most CD and DVD players. Now connect your line inputs to channels 3 and 4 using the wiring guide below .
11 C onnec ting the S zone Connecting the S zone Zone Outputs After you hav e designed a plan for your installation y ou will need to connect the S zone ’ s Zone Outputs to your power amplifiers or pow ered speakers. Y ou can wire the S zone ’ s Outputs for balanced or unbalanced.
12 Using the S zone Input Section The S zone pro vides four stereo inputs that can also be set to accept mono signals . The input channels are where you will connect your sound sources like CD , DVD player , A V monitor output, paging mics or just about an y other audio signal.
13 Using the headphone Any standard headphone with an impedanc e of 8 – 200 ohms can be plugged into the front panel PHONES 1/4- inch jack. W hen a headphone is connec ted to the PHONES input, the internal super speaker will turn off allowing the user or installer to monitor an y zone without disturbing the room ambiance .
14 Setting the Output level It ’ s always a good idea to start with all the Zone Volume controls turned all the wa y down (fully counter-clockwise). Then, follo w these steps. • Once you hav e a signal playing in the input, assign the input to a zone .
15 Setting the Zone Output EQ For V oice T o set the Zone Output equalizer f or vocal operation you want to emphasize the midr ange response. T o do this lower the L OW and HIGH frequency control knobs by about 3dB so set them to the 11:00 position as shown in the following diag ram.
16 Using the Ducker The S zone allow s you to set up a sophisticated music and paging system wher e the background music will auto- matically lower when an announc ement is made. This automatic level c ontrol is known as Duck ing. The S zone’ s ducker can operate with either one or two micr ophones al- lowing two zone paging .
17 Opera ting the S zone Using the Ducker - c ontinued Y ou can set the S zone’ s duck ing matrix to seven settings. The diagram below sho ws the possible settings for using the DUCK ENABLE and MASTER switches . F ollow the grid below and set the S zone Ducker switches to the positions that are best suit ed for your application.
