Redback A4500

Redback 50 Event 24 Hour 7 Day Timer With Evac Tone Generator :: A4500

The A 4500 is a weekly timer and Evacuation controller all housed in a convenient 1RU rack mount chassis. A total of 50 event switching times are available through the timing functions. Each event can be set to turn on any single day of the week or on multiple days, from 1 sec up to 24 hours. When a timing event is activated, an MP3 audio file will be played and output through the dual RCA line level output. There are three MP3 playback options for the timing events, which include the Bell, Prebell and a Music option. An SD card which is supplied, houses all the MP3 files to be played as well as storing all the timing events (Note: The audio files must be in MP3 format). The timing events can be programmed via the units front buttons which is a bit cumbersome, or they can be programmed with the supplied PC software (also available as a download).

The timing events can also be programmed to only trigger the Bell 24V out (and in turn the common 24V Out), with no audio output. This is activated by setting the output to the relay option in the programming setup.

The Evacuation controller is designed around industry standard building emergency alert/evacuate requirements. When connected to a paging system amplifier, building occupants can be alerted and/or evacuated in the event of an emergency e.g. fire, gas leak, bomb scare, earthquake. Alert &Evac switches on the front of the unit are fitted with safety covers to prevent accidental operation.
The Alert, Evacuation and Bell tones and the cancel function are triggered by the front switches, or by the rear terminal contacts for remote activation. Switched 24V DC Out connections are provided for Bell, Alert, Evac or a Common out. These contacts are for connection of override relays in remote volume controls, warning strobes, bells etc.

The alert and evacuation tones are stored on the SD card (Emergency Tones which conform to AS1670.4 are supplied) to allow the user to provide any tones they require (Note: The audio files must be in MP3 format).

The Evacuation mode has a voice over option for the playback of an evacuation message every third cycle of the evac tone. The voice over message is also stored on the SD card and is DIP switch enabled.

Programming the Timing Events
The timing events can be programmed via the units front buttons which is a bit cumbersome, or they can be programmed with the supplied PC software (Screen shots shown below).

Programming the A 4500 with the software is very simple.
Open the program by double clicking the Redback A 4500 Timer Programmer.exe file. The program will appear as shown below.

If the program doesn't run then the .NET Framework might need to be updated on your PC. This must be updated to the .NET Framework 4, available on the microsoft website.

Redback A5330

Redback Mono 31 Band Graphic Equaliser - 1U 19" Rack Mount :: A5330

Graphic equalisers can be invaluable for counteracting poor room or venue acoustic problems such as feedback and reverberation. The audio spectrum is divided across 31 notch bands each adjustable plus or minus 6 or 12dB from centre or flat position. Feedback or reverberation can be reduced or eliminated by “notching out” ie. reducing the system frequency response at the offending frequency sector. Usually connected between the pre amp out and power input of the sound system amplifier. An earth lift switch helps eliminate mains earth loop hum and buzz. High pass and low pass selectable filter switches provide filters of 12dB per octave below 40Hz and above 16kHz respectively. Three different types of connectors are provided for connection to the amplifier. 3 pin XLR and 6.35mm sockets offer balanced connections, whilst RCA sockets provide unbalanced operation. A switch is provided to bypass all control settings. Overall output is controlled by the level control.
Removal of AC power in the ON position puts unit into bypass mode making this suitable for 24V backup systems

Redback A5350

Redback 2 Way Stereo/3 Way Mono Active Crossover + Subwoofer :: A5350

A rack mount active crossover may be configured in either stereo 2- way or mono 3-way mode. Designed to be used in a multi-amplifier, multi-speaker PA or front of house system, it accepts a balanced line input via XLR connectors on the rear panel. Output connectors are all balanced XLRs.

The crossover frequencies can be adjusted from 45 to 960Hz, with a x10 scale selector allowing adjustment from 450Hz to 9.6kHz. Gain controls are provided for inputs and for the separate low, mid and high bands. This flexibility allows the system output to be tuned, using the crossover, to suit the speaker system in use and the venue acoustics. Having established as linear a response as is possible by adjusting the crossover filter points and gains, an equaliser such as the A 5330 can be used to fine tune the system.

A separate subwoofer output socket and gain control is provided, with the subwoofer low-pass point adjustable from 20Hz to 200Hz. This output is available in either 2-way or 3-way mode. When using the subwoofer output, a “low cut” switch enables all frequencies below 40Hz to be cut from the other crossover outputs. In a multicabinet system this can be employed to protect the mid/bass drivers from damage caused by powerful sub-bass signals. To provide further signal adjustment, phase invert switches may be used to reverse the polarity of the low, mid or high output signals.

Features:
• 1U 19" rack mount
• Stereo 2-way or Mono 3-way modes
• Adjustable input and output gains
• Balanced XLR inputs and outputs
• Separate subwoofer output with 20Hz to 200Hz adjustment

Redback A2065

Redback Single Zone Module - 15-35V :: A2065

This module has been designed to monitor the integrity of 100V Line speaker circuits. It is connected between the amplifier output and the speaker circuit. The module will detect one of three speaker line conditions. (Normal, Short Circuit or Open Circuit). LED indication is provided for each condition. A switched output is provided for each of the fault conditions. These may be used for sounding an alarm or muting the input of the amplifier to prevent excessive current draw in the event of a short circuit. Several modules may be connected to one amplifier for multi-zone installations. To function correctly, the speaker circuit must be wired on a loop-in, loop-out basis with a 100K Ohm end-of-line resistor fitted across the speaker line at the last transformer.Important Note: All speakers must be fitted with a 22΅F Bi-Polar capacitor fitted on the input of the transformer.

Features:
LED Status Indicators
Two switched outputs
Operates from a wide supply voltage (15-35 volts DC)
Screw Terminals for all connections
