3000 Series Modules General Descriptions

Modules require CMF-1000A or CMF-3000B.

A wiring and connector charge is required per Module.




1 Input x 6 Output Audio Distribution Amplifier Accepts a single balanced or unbalanced audio input and provides up to six balanced or twelve unbalanced outputs.  Input impedance: 200K ohms; Output impedance: 600 ohms (balanced) or 150 ohms (unbalanced); Input level: 0 to +8 DBM; Gain: 25 dB; Freq. Response: +\- 0.5 dB, 10 Hz to 30 kHz; Hum and noise: 80 dB down with +20 DBM output; Output isolation: greater than 50 dB; Distortion: 0.1% or less.




Audio Level Controller - is designed to compensate for audio levels constantly fluctuating within any program and that also occur while making local or network transitions.  Each ALC-3001B can be integrated into existing insertion or automation system.  Up to 12 stereo or 24 mono channels can be provided per CMF-3000B frame.  Two monaural or one Stereo channel is provided per module.  The ALC-3001B allows user-programmable attack and recovery ranges, independently adjustable for each module.  Adjustment is made by coding the DIP switch mounted directly on each printed circuit board.




Vertical Interval Stereo Audio/Video Switch Accepts two inputs of stereo audio and video and routes selected input to the output bus.  Additional AVS-3021A modules may be cascaded together into a common output bus for situations requiring more than two inputs.  Total solid-state design insures that vertical interval switching occurs automatically with synchronized inputs to provide glitch-free, broadcast quality transitions.  The selected A/V crosspoint is latched ON with a 5V, negative-going pulse or a momentary closure to ground from a remote pushbutton.  Required logic pulses are available from other 3000 series equipment and the AVS-3021A may also be operated manually with a front panel pushbutton.




Vertical Interval Audio/Video Switch Accepts up to three inputs of unbalanced audio/video inputs and routes selected input to output buss.  Additional AVS-3031B modules may be cascaded together into a common output buss for situations requiring more than three inputs.  Vertical interval switching occurs automatically with synchronized inputs to provide glitch-free, broadcast quality transitions.  The selected crosspoint is latched ON with a 5-volt, negative-going pulse or a momentary closure to ground from a remote pushbutton.  Required logic pulses are available from other 3000 Series equipment and the AVS-3031B may also be operated manually with a front panel pushbutton.  A built-in auxiliary relay allows the AVS-3031B to control other equipment such as scramblers or logging devices.


AVS-3031C  Same as AVS-3031B but with Stereo Audio.




Audio/Video Switch A two A/B (2x1), non-synchronous audio/video switcher that uses relays for switching.  The audio switched can be either unbalanced stereo or balanced monaural.  All inputs are properly terminated in the Off mode.  Requires a rack frame (PCM or LCC) and power supply.




Blank Filler Panel for CMF-3000B Frame Color-coordinated metal filler used to cover unused module spaces.  The number of spaces to be covered is specified by the XX in the part number.  (BFP-3001A occupies one space; BFP-3009A occupies nine spaces).




Card Extender for 3000 Series Modules Allows any 3000 Series module to be accessed for testing or adjustment while in operation.  Also provides test points for each card edge connector terminal.




Rack Mounting Frame Provides housing for up to twelve 3000 Series modules and one power supply.  Size: 3 ½ inches high x 10 ¼ inches deep x 19 inches wide (standard EIA rack mounting).




16-Digit DTMF Tone Decoder Provides discreet control signals from telephone type dual tone, multifrequency tones.  May be used directly on dedicated audio paths or in conjunction with the UAD-3000A Unattended Telephone Answering Device Module.  Applications include the remote selection of satellite receiver channels when used in conjunction with the SRC-3001A Satellite Receiver Controller Modules.




Digital High-Speed DTMF Tone Decoder Monitors satellite receiver program audio and provides start and stop signals to activate automation and/or signal switching equipment to add locally generated material in the predesignated spots identified with the cuetones.  Compatible with standard telephone touchpad tones, the module can be adapted to many remote control applications. A PCB mounted programming switch is provided for selection of a number of digits to be decoded and type of output signal desired.  Front panel LEDs indicate status of all module functions. Input level: 0.7 to 2.0V p-p.  Input impedance: (dual) High: 50K ohms, Low: 600 ohms.




High Speed DTMF Tone Generator Portable, battery-operated unit produces standard telephone-compatible DTMF tones for simulating telephone or satellite service DTMF tone data to control or enter data into equipment requiring telephone-type tones.  Data entry is easily performed using a 16-digit keypad.




DTMF Tone Generator Provides two sequences of four DTMF tones, comprising of either a START or END function.  Front panel pushbutton switches, internal jumpers, and control inputs on the edge connector can be used to select various output combinations.  Three sets of DIP switches on the circuit board determine the first three digits in the sequence.  The last digit is determined by the pushbutton or control signal.  If an audio signal has been connected to the audio input, the audio will be muted, and the tone sequence will be inserted in its place.  All DTMF tones generated will be at the same speed as the satellite networks, and are able to control all Channelmatic devices capable of processing and acting on DTMF cuetones.  The DTG-3001A allows the user to simulate a four digit DTMF tone burst that a satellite network would send to indicate a commercial-begin and commercial-end sequence.  The tone burst consists of four digits: the first three digits from 0 through 9 and the last digit will consist of either a * or #.  The user can modulate the output of the generator, if needed, and transmitted to a remote site.




Frame Wiring and Documentation Service charge added to the price of the custom systems to cover: wiring custom backplates, constructing custom rear panel connector layouts and designing and documenting custom module interconnections from customer specifications.  Charge is computed on a per module intermodule basis.  Customer is furnished with complete documentation package including intermodule wiring diagrams and module manuals.




Prototype Kluge Breadboard Etched and drilled perfboard Kluge module compatible with CMF-3000B frame.  Used when it is desirable to implement a custom circuit without the added cost and time delay of generating a final production-type etched circuit board.

Regulated Triple Output Power Supply 110v 60HZ Mounts in a CMF-3000B Custom Frame and provides power for up to twelve 3000-Series modules contained within the same frame.  This module supplies regulated +5VDC, +12VDC, and 12VDC as well as unregulated 17VDC and +17VDC through the Edge connector in the frame.  AC Power is supplied to the RPS-3002A via the Rear Mounted I/O panel with a voltage Regulator and Fuse.




Universal Power Supply 110V-220V 50/60HZ The External Power Supply mounts to the rear of the Rack, and provides power through a custom power cable attached from the RPS-3002B Rear Mounted I/O panel to the RPS-3002B Rack mounted Power Supply.  This module supplies +5VDC and ±12VDC for up to two CMF-3000B Custom Frames. A Power Indication and Distribution Module are included. In addition to supplying power to all modules (1 to 12 modules) contained within the frame, the Power Indication and Distribution Module indicates when +5VDC, +12VDC and 12VDC power is coming from the External Power Supply.




Sync Presence Detector Designed to accept a composite video signal and continuously monitor it to ensure presence of a valid signal.  This is done by stripping the vertical sync from the input video signal and checking it for excessive noise and missing sync pulses.  If either condition is detected, the front panel Valid Video LED will extinguish and the module will automatically switch its internal relays from the normally closed (N/C) contacts to the normally open (N/O) contacts and the Relay On LED will illuminate.  The contacts will stay switched to the N/O position until the primary video signal is restored and is at an acceptable quality level.  A front panel switch is provided to disable the relays if necessary.  A high impedance sense input monitors an incoming video signal and controls the SPDs on board relays based on the presence or absence of video on the same input.  The SPD-3001A relay contacts can either be wired to perform two input, one output audio/video switching or the relays can be wired to provide a logic or control voltage output which, in turn, can control an external alarm or switch equipment based on the presence or absence of the primary video signal.  Solder pads are available on the modules printed circuit board for installing audio and video termination resistors for audio/video switching applications.




Universal Audio Amplifier Unit accepts three independent balanced audio inputs and provides three independent unbalanced audio outputs with unity gain.  Module also accepts one unbalanced audio input and provides two amplified balanced audio outputs with common gain control and selectable AGC.  Normally used to add balanced audio to the AVS-3031B Switch Module.




Unattended Telephone Answering Device Provides a means of controlling equipment at remote locations using standard telephone lines for transmission paths.  Unit will answer either rotary or tone dial telephones, but sending control signals necessitates the use of either a tone dial telephone or a DTG-103A DTMF Tone Generator.  Front panel controls permit adjustment of number-of-rings before activation and dwell time before circuit release.  Front panel LEDs indicate ring and on-line status.  System may be manually overridden by simply picking up the telephone receiver.  Designed to be used in conjunction with either the CTD-3001B 16-Digit DTMF Tone Decoder or the CTD-3104A 4-Digit DTMF Tone Decoder for remote equipment control.
