Antenna Connections

FM Indoor AntennaIn an area with strong FM signals, the “T“-type FM antennaprovided is sufficient. Extend this into a “T“ shape and con-nect the two wires at the base of the T to the antenna termi-nals , as shown. For details of how to connect the antennawires to the terminals, see the illustration.Extend the top of the T and fix with thumb tacks, or the like,to a wall or window frame for the best possible reception.

AM (MW) Antenna

AM Indoor Loop AntennaA high-performance AM loop antenna provided with thereceiver is sufficient for good reception in most areas.Connect the loop antenna’s wires to the AM antenna ter-minals as shown. Place the antenna on a shelf, forexample, or hang it on a window frame, etc., in the direc-tion which gives the best reception, as far away as pos-sible from the entire system, speaker cords and thepower cord, to prevent unwanted noise.

AM Outdoor AntennaIf the AM loop antenna provided does not deliver suffi-cient reception (because you are too far from the trans-mitter or in a concrete building, etc.), it may be neces-sary to use an outdoor AM antenna. Use an insulatedwire more than 15 ft (5 m) long, strip one end, and con-nect this to the terminal as shown. The antenna wireshould be strung outdoors or indoors near a window.For better reception, connect the GND terminal to a reli-able ground.

Note : Even when using an outdoor AM antenna, do not dis-connect the AM loop antenna.

FM Outdoor AntennaIn an area where FM signals are weak, it will be necessaryto use a 75-ohm unbalanced-type outdoor FM antenna.Generally, a 3-element antenna will be sufficient; if you livein an area where the FM signals are particularly weak, itmay be necessary to use one with 5 or more elements.A 75-ohm antenna uses a coaxial cable and should be con-nected as follows: first strip the covering of the cable, thentwist the wire shielding so the inner core and shielding canbe connected as shown.

SURROUND EFFECTS

When you use a surround function, the PLR-85 creates a“live” atmosphere such as that experienced in movie theatersand concert halls.

Speaker PositioningOptimal speaker positioning differs according to the size,and acoustics of the listening room. While actually listeningto a program source, try various speaker positions to deter-mine which layout provides the best surround effect.

Speaker layout example when using DOLBY PROLOGIC surround

DOLBY 3 STEREODolby 3 Stereo Mode is useful for the customer who doesnot want to install the rear speakers. The mode provides theeffect of sound simllar to Dolby Pro Logic without rearspeakers.

Surround ModesThis unit is equipped with the following surround modes,which can be selected using the SURROUND MODEswitches.Select the appropriate surround mode according to the pro-gram source.

HALL

When playing recordings of live music, this mode provides afeeling similar to actually being in a concert hall. When thismode is selected, the normal program source is directed tothe main speakers and a reverberated sound is directed tothe surround speakers.

THEATERThis mode provides a three dimensional effect similar to thatof movie theater. With this mode, you can enjoy a surroundeffect similar to Dolby Surround sound even when playing avideo program which is not encoded with the DolbySurround system.

STEREO (Bypass)

Use this mode when surround effects are not desired.

Front-Lautsprecher

Center-Lautsprecher

Rear speakers

For best effect, do not install the rear speakers too farbehind the listening position and install them above thelevel of the listener’s ears. When not using a center speaker with the DOLBY PROLOGIC surround function, set the center mode to PHAN-TOM. This will send the center channel information to theleft and right main speakers.

HALL, THEATER ModesWhen using HALL or THEATER surround modes, the centerchannel speaker does not operate.

No center speaker

Front(Left) Front(Right)

(Left)-Rear-(Right)

DOLBY PRO LOGICUse this mode when playing movie or music video softwarewhich carries the DOLBY SURROUND mark.This mode provides the effect of being in a movie theater orlive concert house.The main feature of DOLBY PRO LOGIC SURROUND isthat the separation between the various channels is signifi-cantly improved from the 3 dB of previous systems to 26-40dB. As a result, the effect of the front/back/ left/right move-ment of the sound image, is much clearer and more dynamicthan ever before.In addition, movie dialogue and other sounds which shouldnaturally be heard from the center are output through anindependent center channel, providing a high degree of fou-cus for dialogue.

CENTER MODE

There are 3 kinds of center modes when operating inDOLBY Surround mode. Select the desired mode suitable toyour speaker system.

NORMAL ModeUse this position when the center speaker is a compact speaker which is not capable of fully reproducing bass frequencies below 100 Hz. In this mode, the bass fre-quencies below 100 Hz are distributed to the front left and right speakers.

WIDE ModeUse this position when the center speaker is an equivalentspeaker to the front left and right speakers or when itis capable of fully reproducing bass frequencies below100 Hz.

PHANTOM ModeUse this position when the center speaker is not used.The center channel sound is distributed to the left andright front speakers.

* Dolby 3 Stereo has only NORMAL and WIDE modes, not PHANTOM mode.

DELAY TIME

In the surround modes, the sound from the rear speakersshould be delayed slightly, relative to that from the frontspeakers. The optimum delay time will depend on acousticproperties, whether the walls and furnishings reflect orabsorb sound, etc..It is recommended that you try different delay times toobtain the best effect. The delay is digitally synthesized, forthe highest sound quality with minimum noise and distortion.The delay time can be set independently for each surroundmode using the DELAY TIME button, with the current settingshown in the display.

TEST TONETo enable the user to accurately set speaker system bal-ance when operating in surround mode, a steady test signalis played in one channel at a time and the levels can beadjusted until they match each other.A mid-frequency noise signal is used so that it will soundsimilar from all speakers in the system regardless of size orlocation.The noise is automatically switched through the four chan-nels, L-C-R-S, lasting about two seconds in each.

When the center mode is NORMAL or WIDEBAND :The test tone is output in order of Front Left speakerCenter speaker Front Right speaker Rear speakers.

When the center mode is PHANTOM :The test tone is output in order of Front Left speakerFront Right speaker Rear speakers.

When the surround mode is Dolby 3 Stereo :The test tone is output in order of Front Left speakerCenter speaker Front Right speaker.

The rear and center speaker volumes can be adjusted in 1dB steps from -10 dB to +10 dB.

Note on delay time

By adjusting the very small time difference between thesound output from front speakers and the sound outputfrom the rear speakers (that is referred to as the delaytime), it is possible to change the surround sound fieldcreated by the surround effect.

ln the DOLBY PRO LOGIC mode, the delay time adjust-ment range is limited by the Dolby specification tobetween 15mS and 30mS.In Hall/Theater modes, you can select between 15mSand 50mS depending on personal preference.

Suitable Delay Time in DOLBY PRO LOGIC SurroundPlay

IMPORTANT :The test tone only operates when the unit is in Dolby ProLogic or Dolby 3 Stereo mode. It will not operate in stereo, Hall or Theater modes.
