Switches



624B
Video Sensor

Monroe Electronics’ Model 624B Video Sensor provides automatic 2x1 balanced stereo-audio-follow-video switching, controlled by Video sync pulses.

The 624B detection circuit monitors the loss of composite sync pulses on the primary video input. It automatically switches to the secondary video input upon loss of sync pulses. It remains in this state until the primary video returns, prompting the 624B to switch back to the primary video input.

This state of the art configuration allows accurate, clean, dependable switching in unattended locations.

625A
RF/IF Sensor

Monroe Electronics’ Model 625A RF/IF Sensor provides automatic 2x1 RF/IF switching controlled by the loss of video modulated RF carrier.

The 625A’s sense input circuit monitors horizontal sync pulses on the video modulated RF carrier and automatically switches to the secondary input upon a decrease or loss. The relay remains in this with the secondary input connected to the output, until the sync pulses on the video modulated RF carrier return. This causes the primary input to switch back to the output connection.

The 625A’s sensing input requires an external bandpass filter and pad for multiple channel feed conditions.

627A
A/V Switch

Monroe Electronics’ Model 627A Stereo Audio/Video Switch module provides 2x1 (AB) balanced stereo audio follow video switching.

The 2x1 switch will respond to a contact closure or a transistor switch to ground or a compatible logic level. The control input is buffered to eliminate high output current drive requirements of the controlling device.

The 627A can be controlled by Monroe Electronics program timers, remote controls or CATV Cue Tone receivers.

628
Encoder Sensor

Monroe Electronics’ Model 628 Encoder Sensor automatically switches in an alternate program feed whenever you stop
scrambling!

The 628’s Sensor input samples scrambled baseband video for sync suppression, such as from a Jerrold MVP-II Encoder.

When the sensor circuit detects sync suppression it causes the 628’s secondary input to be connected to the common output. It will remain in this state until sync suppression stops, which causes the 628’s primary input to be connected to the common output.

R159A
Sync Sensor Video Backup Switch

The Model R-159A Switch monitors composite baseband video sync from a single channel, for 3 separate channels. It outputs each baseband video signal, and its accompanying composite audio, to two separate output connectors.

When baseband video loses sync or its level decreases by more than 3 dBmV, the R159A switches to a secondary baseband input with composite audio. When the original signal returns, it will switch back to the original signal pair.

At the same time, the switch change activates a remote indicator solid state switch on the back panel, for status monitoring systems, as well as an LED on the front panel, for local troubleshooting.

Each switch section can be overridden by an external contact closure to ground.

R164
Stereo A/V Switch

Monroe Model R164 Stereo Audio/Video Switch module provides 2x1 (AB) balanced stereo audio follow video or  IF/RF switching.

The 2x1 switch will respond to a contact closure, a transistor switch to ground or a compatible logic level. The control input is buffered to eliminate high output current drive requirements of the controlling device.

The R-164 can be controlled by Monroe Electronics’ program timers, remote controls or CATV Cue Tone receivers.

R165A
Stereo A/V and IF/RF Relay Panel

Monroe Electronics’ Model R-165A Audio/Video Relay Panel provides four, independent 2 x 1 (A/B) balanced stereo audio follow video relay switches. The switches are controlled by Monroe Electronics’ program timers, remote controls or CATV Cue Tone® receivers via contact closures or logic inputs.
Each video relay will also function as a high quality IF/RF 2 X 1 (A/B) switch, with frequency response to 950 MHz.
Auxiliary relays 1 & 2 available for GPI or SAP switching.

R174A
A/V Relay Panel

The Model R174A Audio/Video Relay Panel provides four, independent 2x1 (A/B) balanced stereo audio follow video relay switches. They may be controlled by Monroe Electronics’ program timers, remote controls or CATV Cue Tone receivers via contact closures or logic inputs.

They may also be controlled individually or in groups via an RS-485 interface. Switchware2, an optional Windows® based software, is supplied for this purpose, and allows up to 32 panels to be controlled via one PC. Each video relay will also function as a high quality IF/RF 2 x 1 A/B switch, with frequency response to 950 MHz.

Each A/V switch has an individual, separately programmable DTMF (Cue Tone) switch to turn the relay on or off. The ON command pulses a relay output to start a VCR or signal a Digital Ad insertion system.

R175
Stereo A/V Vertical Interval Switch

Monroe Electronics’ Model R175 Stereo Audio/Video Switch provides 2x1 (AB) balanced stereo audio follow video switching during the vertical blanking interval.

The 2x1 switch will respond to a contact closure, a transistor switch to ground, or a compatible logic level. The control input is buffered to eliminate high output current drive requirements of the controlling device.

The switch requires a valid video signal on the primary input to switch.

The video output from the switch is buffered to drive a 75 ohm cable. The Baseband stereo audio is switched via dry contact relays.

The Model R175 can be controlled by Monroe Electronics program timers, remote controls or CATV Cue Tone® receivers.

R176
Stereo A/V Vertical Interval Switch

Monroe Electronics’ Model R176 Stereo Audio/Video Switch provides 2x1 (AB) balanced stereo audio follow video switching during the vertical blanking interval.

The 2x1 switch will respond to a contact closure, a transistor switch to ground or a compatible logic level. The control input is buffered to eliminate high output current drive requirements of the controlling device.

The switch requires a valid video signal on the primary input to switch.

The unit also has an input for -20 to +3 dBmV DTMF commands for switching the A/V inputs. The code sequence may be entered using a standard Touch Tone telephone during setup, and is stored in non-volatile RAM.

The video ouput from the switch is buffered to drive 75 ohm cable. The Baseband stereo audio is switched via dry contact relays.

The Model R176 can be controlled by Monroe Electronics program timers, remote controls or CATV Cue Tone receivers.

R192
Multi Channel Backup Switch

Each of the R192’s ten (10) individual detection circuits monitor the loss of composite sync pulses on the primary video input. They will automatically switch to the secondary video input upon loss of sync pulses. It will remain in this state until the primary video returns, causing the section to switch back to the primary video input.

When a switch section loses primary video and switches to the secondary, the red led panel indicator, for that sensor on the front of the R192, lights up.
