Installation and Connections
System Installation
After unpacking the unit, and placing it on a solid surface capable of supporting its weight, you will need to make the connections to your audio and video equipment.
Audio Equipment Connections
We recommend that you use
When making connections to audio source equipment or speakers it is always a good prac- tice to unplug the unit from the AC wall outlet. This prevents any possibility of accidentally sending audio or transient signals to the speak- ers that may damage them.
1.Connect the analog output of a CD player to the CD Inputs •.
NOTE: When the CD player has both fixed and variable audio outputs it is best to use the fixed output unless you find that the input to the receiver is so low that the sound is noisy, or so high that the signal is distorted.
2.Connect the analog Play/Out jacks of a cas- sette deck, MD,
3.Connect the output of any digital sources to the appropriate input connections on the AVR 120 rear panel. Note that the Optical and Coaxial Digital Inputs de#$ may be used with a Dolby Digital or DTS source or the output of a conventional CD or LD player’s PCM
4.Connect the Optical Digital Output ª or Coaxial Digital Output ‚ on the rear panel of the AVR 120 to the matching digital input connec- tions on a
5.Assemble the AM Loop Antenna supplied with the unit as shown below. Connect it to the AM and GND Screw Terminals ¢.
6.Connect the supplied FM antenna to the FM Antenna (75 ohm) Connection ¶. The FM antenna may also be an external roof antenna, an inside powered or wire lead antenna or a connection from a cable TV system. Note that if the antenna or connection uses
7.Connect the front, center and surround Speaker Outputs ›fi to the respective speakers.
To ensure that all the audio signals are carried to your speakers without loss of clarity or reso- lution, we suggest that you use
Regardless of the brand of cable selected, we recommend that you use a cable constructed of fine, multistrand copper with a gauge of 14 or smaller. Remember that in specifying cable, the lower the number, the thicker the cable.
Cable with a gauge of 16 may be used for short runs of less than ten feet. We do not recom- mend that you use cables with an AWG equiva- lent of 18 or higher due to the power loss and degradation in performance that will occur.
Cables that are run inside walls should have the appropriate markings to indicate listing with UL, CSA or other appropriate testing agency stan- dards. Questions about running cables inside walls should be referred to your installer or a licensed electrical contractor who is familiar with the NEC and/or the applicable local build- ing codes in your area.
When connecting wires to the speakers, be cer- tain to observe proper polarity. Remember to connect the “negative” or “black” wire to the same terminal on both the receiver and the
speaker. The AVR 120 is one of the first audio products with the latest
Left Front = White | Right Front = Red |
Center = Green |
|
Left Surround = Blue | Right Surround = Grey |
NOTE: While most speaker manufacturers adhere to an industry convention of using black terminals for negative and red ones for positive, some manufacturers may vary from this config- uration. To ensure proper phase and optimal performance, consult the identification plate on your speaker or the speaker’s manual to verify polarity. If you do not know the polarity of your speaker, ask your dealer for advice before pro- ceeding, or consult the speaker’s manufacturer.
We also recommend that the length of cable used to connect speaker pairs be identical. For example, use the same length piece of cable to connect the
8.Connections to a subwoofer are normally made via a
Video Equipment Connections
Video equipment is connected in the same man- ner as audio components. Again, the use of high- quality interconnect cables is recommended to preserve signal quality.
1.Connect a VCR’s audio and video Play/Out jacks to the Video 1 Input Jacks £a on the rear panel. The Audio and Video Record/In jacks on the VCR should be connected to the Video 1 Out Jacks ∞· on the AVR 120.
