3 FEATURES Your new processor i s a versatile audio/video control c ente r. The processor is designed to sound sensational a nd be an attractive, easy-to-use addition to your audio/video system. Although you already have a good idea of your processor’s features, we woul d like to take a moment to point out certain highlights.
4 THE BASICS The following is intended to familiarize users with common terms and applicati ons of Home Theater equipment. Sources - your proc essor can provide audio from its built-in AM/FM tuner. It can also provide limited video from its on-screen menu sy stem.
5 Stereo - Stereo contains two di screte, front left and right full range audio channels. Thi s is the most common format for music and i s also used on many movies.
6 DTS NEO:6 – DTS Neo:6 is an advanced matrix decoder. It will ta ke any two-channel source and expand it into five or six channels, depending on the user’s speaker lay out. Two-channel sources include VHS tapes, broadcast television, stereo CDs and DVDs.
7 THX Surround EX ™ - Dolby Digital Surround EX is a joint development of Dolby Laboratories and the THX division of Lucasfilm Ltd. In a movie theater, film soundtra cks that have been encoded with Dolby Di gital Surround EX technology are able to reproduce an extra channel, which has been ad ded during the mixing of the program.
8 Bass Management - Dolby Digital and DTS-ES form ats may contain up to 6 full range channels plus LFE. Only a system with six full-range (large) s peakers plus a subwo ofer can directly reproduce these formats.

Red RCA jack - typically connect to the red out put of a component video source Green RCA jack - typically connect to the green out put of a component video source Blue RCA jack - typically connect to the blue out put of a component video source 13.
12 MAKING THE CONNECTION It’s tempting to just plug in your n ew A/V processor and have great sou nd pour out. Before you do that, take a few minutes to plan out how you want the proce ssor to fit into your audio/video system. Ask yourself the following questions: What source components do I want to conne ct to my processor? (CD, VCR, etc.
13 AUDIO / VIDEO CONNECTIONS Connecting your analog sources to y our processor Audio / Video source - connecting a DVD/VLD player to the processor’s analog in puts. Use the same instructions for connecting to other audio / video source s such as a satellite receiver, cable box, etc.
14 Component Video - In addition to S-video and co mposite video switchin g, your pro cessor provides three sets of component video inputs for DV D and TV/DBS type inputs, and one set of component video output s. Your processors component video connections are passive to minimize the possibility of video format compatibility issues.
15 DIGITAL CONNECTIONS Connect digital inputs (DVD, VLD, etc.) to the processor. You will need either coaxial or optical digital inputs to play Dolby Digital (AC-3) or DTS surround sound p roce ssing. Digital connections are also recommended fo r PCM sources.
16 SURROUND OUTPUTS Your processor has multiple surrou nd processor outputs fo r use with external amplifier(s) or powere d speakers. The Reference 50 proce ssor allows THX Surround EX co mpatibility via two Surround Back ‘S BACK’ processor outputs.
17 SURROUND SPEAKER OUTPUT CONNECTIONS Connect the A/V System Controller’s surroun d outputs to your external amplifier(s) or powered speakers as described previously.
18 ANTENNA CONNECTIONS The FM jack is a stan dard screw on F-type connector. The AM is a push type. Strip ¼ inch of insulation off your AM antenna wires and insert one wire end into each hole whil e holding the tabs down. Release the tabs to lock in the AM antenna wires.
19 FREQUENTLY AS KED QUESTIONS My collection of equipment differs fr om the labels on the back of my processor, how can I hook them up? Your processor provides 5 identical sets of inputs - V1, V2, DVD, CD, and SAT. Each of the se has analog audio, composite video, S-video, coaxial digital audio, and optical digital a udio.
20 My laser disc player (or other digital source) has only op tical output, but my CD recorder (or other digital recorder) has only coaxial input. Do I need some sort o f converter to make direct digital recordings? No, your processor will convert optic al to coaxial and coaxial to optical.

To perform a backup, follow the procedure below. To restore backup settings perform the same proced ure bu t select restore inst ead of backu p.
45 OPERATION The following outlines the norm al day-to-day operation of your processor from the supplied universal remote or directly from your processo r’s front panel. The universal re mote is also capable of controlling other equipment and storing sequences of commonly used commands.
46 CHOOSING A SOURCE In general, the selected source will ap pear at the Zone 1 output, the TAPE ou tput, and the V1 output. To prevent feedback, TAPE input will not appear at TAPE output and V1 input will not appear at V1 output.
47 ADJUSTING THE VOLUME From Remote From Front Panel Action VOLUME + or VOLUME − VOLUME KNOB adjust volume MUTE can’t do from front panel instant volume all the way down press MUTE again to resto re Note: The front panel VOLUME KNOB is used to control mult iple functions and, theref ore, cannot always control the volume.
48 AUDIO MODES Your processor is designed to work with 5 audio list eni ng modes. Under normal operation you may simply select Mono, Stereo, Surround, THX or DVD Audio via the remo te control. In addition, you may choose an audio listening mode immediately followed by a speake r selecti on.
49 Audio Mode description MONO Sums the incoming audio information to a single channel a nd routes it to the desired speaker. Use this mode for listening to the FM tuner with weak RF signal stre ngths. It is also useful in the case of a large listening group and it is difficult to put everyone near the optimum listening position.
50 Neo:6 Movie (Cinema) When listening to movies using the DTS Neo:6 movie (c inem a) decoder with stereo TV shows or other surround- encoded programs, there is further e nhancement to soundfie ld directionality, which is close to the quality of discrete 6.
51 Special Considerations For use with multi-channel encoded bitstreams p ressing of SURROUND or THX toggles between the Movie and Music playback options.
52 Why do I need all these audio modes? With the wide variety of audio source material ava ilable today, i.e. single channel mono, 2 channel mono, 2 channel stereo, 2 chann el surround and multi-channel encode d au dio, we believe that the reproduction of this material is best handled in audio categories.
53 EQUALIZATION ‘EQ’ Selecting an EQ functio n via the remote control - all ows you to override how the audio i s currently being processed. This is where you may se t the Dynamic Range to eit her Normal (default) or Limited for late night listening while processi ng Dolby Digital or DTS bit streams.
54 Select Dynamic Range Limited For late night listening while proce ssing Dolby Digital or DTS bit streams and a redu ced dyn amic range is desired. When the dynamic range is set to limited, compre ssion is used to raise the average loudness of the dialog, and the program peaks will be restricted much in the style of conventional television audio.
55 ZONE ‘Z’ Use the Z (zone) func tion via the remote control - For use in a second audio zone, your processor comes equipped with a fully independent 2-ch annel analog pre-amp.
