Cat. No. 735 Auditorium Assist Microphone

The Dolby Cat. No. 735 microphone, mounted permanently and inconspicuously in the auditorium, works in conjunction with the Auditorium Assist feature provided in all CP650s to help you maintain consistently high performance from your cinema’s sound system.

Once your room is initially aligned, Auditorium Assist uses the Cat. No. 735 to take measurements of the frequency response and level of each channel, plus the room’s ambient noise floor, which are then stored within the CP650 as your Auditorium Reference. Thereafter, whenever you run Auditorium Assist, it takes the measurements again and compares them to the Auditorium Reference, all in less than 90 seconds. You are alerted to any discrepancies to help you diagnose and resolve faults that may have occurred in the speakers or other system components.

Cat. No. 790 Dolby Digital Surround EX/Digital Input Card

The Cat. No. 790 card, which is standard in the CP650 and CP650XO configurations, provides Dolby Digital Surround EX decoding. It also provides four AES3 inputs that accommodate up to eight channels of digital audio
(at 44.1 and 48 kHz) from sources such as digital cinema servers, disks, tape playback systems, and satellite or cable links. The CP650 converts the digital audio to as many as six channels of analog audio (up to eight channels with a Cat. No. 791 installed) for playback through your sound system.

Cat. No. 778 Digital Input/Output Card (not shown)

For dubbing studios requiring digital input and output, the Cat. No. 778 Digital Input/Output Card can substitute for the Cat. No. 790 to provide four AES/EBU digital inputs and up to five AES/EBU digital outputs.
(The Cat. No. 778 disables the CP650’s analog output.)

Cat. No. 791 Digital Crossover Card

Cat. No. 791 Digital Crossover Card, which is standard in the CP650XO, integrates two- or three-way speaker crossovers into the CP650 for your L, C, and R screen speakers. It also provides outputs for full-range Le and Re screen speakers.

All audio processing is in the digital domain, enabling extensive settings and adjustments via a PC software package or built-in menus using the front-panel main display. As well as ensuring the highest possible performance from your screen speakers, the Cat. No. 791 eliminates the need for a stand-alone crossover unit.

(A Cat. No. 790 must be installed in the CP650 in order to add the Cat. No. 791.)

Smart mod VI

The MOD VI Cinema Stereo Processor is the first and only processor to incorporate the patented Circle Surroundä technology, the latest innovation in optical stereo soundtrack reproduction. Circle Surround produces 6 channels of audio from a standard optical stereo soundtrack by sensing the slight phase bias on the surround channel when digital masters are mixed down to 4-channel optical tracks. This means you can have split surround optical sound presentations in auditoriums that are equippe for split surround operation.

In addition, the MOD VI utilizes the SRS 3-D sound enhancement system, which brings out sounds that may have been previously hidden by other processors. The MOD VI is the first processor to have both optical and digital tracks benefit from the SRS circuitry to produce fuller, wider and more transparent sound and eliminate the auditorium “sweet spot.” This ensures that the audience will have a full stereo perspective in every seat in the auditorium. Digital soundtracks may be processed in six channel mode which includes split surrounds and subwoofer. To achieve optimum results from your new MOD VI Cinema Stereo Processor, the theatre engineer installing the system should be totally familiar with all features and adjustments. Careful attention to detail and familiarity with the installation instructions will allow you to offer a system that has a sound quality second to none.

FEATURES:

Circle Surround DSP Matrix. The patented Circle Surround produces 6 channels of audio from a standard optical stereo soundtrack. It does this by sensing the slight phase bias on the surround channel when digital masters are mixed down to 4-channel optical tracks. This means you can have split surround optical sound presentations in auditoriums that are equipped for split surround operation. SMART is the first manufacturer to introduce this technology into professional cinema applications. The DSP matrix in the MOD VI produces highly accurate decoding of the optical stereo or SR soundtrack.

SRS 3-D Sound Enhancement. The patented SRS enhancement is a standard feature of the new MOD VI. No longer an expensive option, this process can be turned on or off from a front panel operator switch or by automation. The MOD VI is the first processor to be able to use SRS on optical stereo tracks and digital soundtracks. This process is not active in theaters using Front Surround Mode.

Fader Control/Remote Equalization Settings. The MOD VI has one master FADER that controls the overall playback level for all six channels. This master fader is used as the volume control for all formats. The individual left and right master music level controls are located to the front right of the main circuit board (MR and ML). The octave equalization settings (7 bands plus bass and treble) are set with potentiometers on the front PCB panel, so re-equalizing the MOD VI will not be necessary in the event of a main circuit board replacement.

Format Switching. The formats available on the MOD VI are Mono, Stereo A, Stereo SR, SRS On/Off, Digital and Music. All formats may be manually controlled by the gray pushbuttons on the front panel. Red Light Emitting Diodes mounted in the front pushbuttons indicate the selected format. The indicator LED’s are visible from a distance so it is not necessary to be near the processor to verify the status. Format switching is also possible by connecting an automation or remote switch contacts to the AUTOMATION terminals on the back of the MOD VI.

Solar Cell/Reverse Scan Inputs. The MOD VI has stereo solar cell inputs with electronic changeover for two projectors. Each pair of stereo cell inputs is an electronically balanced circuit that helps to reduce any interference pickup on the solar cell leads. Separate “neutral” leads for right and left channels allow for Reverse Scan wiring. Digital Inputs. The MOD VI is fully compatible with popular digital formats (i.e. DTS, Dolby Digital, etc.). The MOD VI will easily handle the stage, split surround, and subwoofer channels from an external digital decoder.

Music Inputs. The MOD VI is designed to process both stereo and mono music sources from tape, CD or cartridge players. The music is processed through the Circle Surround matrix to produce 6 channels of sound from a stereo music source. In addition, these inputs may be used as an A/V input for use with VCR’s or laserdisc players. The music inputs are run through the Circle Surround matrix. Surround Channel Time Delay. The MOD VI has a digital time delay circuit for the surround channel while playing optical stereo prints. Time delay of the surround channel in optical stereo mode is necessary for two reasons: 1) to mask any front to surround crosstalk and, 2) to synchronize the stage and surround channels to eliminate echo caused by different sound path lengths from the stage and surround speakers.

Main Outputs. The MOD VI has six output channels: LEFT, CENTER, RIGHT, LEFT SURROUND, RIGHT SURROUND and SUB(woofer). The SUB outputs are balanced with SUB+ and SUB- terminals available. This allows a standard dual channel amplifier to be used in mono bridged mode to feed a subwoofer speaker. Main Power Supply. A fully-regulated switching power supply is furnished with the MOD VI processor. This supply is heavily filtered and supplies ample current for both the positive and negative 15 VDC supplies, as well as the logic level 5 VDC supply. This external power supply minimizes the chances of hum pickup when high gain electronic circuits are placed in the same chassis as a power supply. Emergency Sound Backup Power Supply. A 120V backup power supply is included with the MOD VI to power the backup preamp built into the MOD VI. This will ensure that you will never lose a show when using the MOD VI processor.

The 120V backup supply delivers about 12 VDC at 100mA. For installations where 120V is not available, the user should supply their own power supply. The output should be 12VDC @ 100mA and be relatively ripple free. The bypass capability is a standard feature on the MOD VI and is not an extra cost option as it is on other systems. MONO BYPASS supplies sound to the Center Channel only.

Digital Smart Port. The Digital Smart Port allows for future upgrades in the MOD VI, including digital 1/3 octave equalization and Afterburner effects, as well as an alternative port for monitor signals.
