SONIFEX REDBOX AUDIO/VIDEO PROCESSORS

Sonifex Redboxes were introduced in 1999 and were designed for systems integrators. They are very well received in both Broadcast and studio industries. The series of signal processors that include headphone amplifiers, mix-minus generators, silence detectors, tone generators, distribution amplifiers, audio converters and more, are built in two different extrusions, with front and rear panels screwed to the extrusion.

ISOLATION UNITS

These Redbox audio line isolation units, housed in red-anodised aluminium cases, are designed to isolate audio signals from inter-area ground hum-loops which could be caused by equipment being powered by different mains power supplies, or different phases on the same supply.


RB-PLI6 - Passive Line Isolation Unit

The input and output of the passive line RB-PLI6 are connected together through a transformer, and the unit has internal jumpers allowing the inputs and/or outputs to be balanced about ground. The unit requires no mains power for operation. This unit is useful where audio is required to be driven over a relatively long length of cable. By isolating the signal using transformers, ground loop currents which can be present in non-isolated signals, are eradicated completely.

Inputs: Six XLR 3-pin female, balanced. Outputs: Six XLR 3-pin male, balanced.

Output impedance: <150 ohms. Distortion: 0.5% THD, 40Hz, +17dBu output. Common mode rejection: >64dB typically. Frequency response: 10Hz to 36kHz +/- 0.5dB. Dimensions (WxDxH): 480 x 108 x 42mm, 1U. Weight: 1.5kg

Included accessories: Handbook, IEC lead with UK 13A plug.
Optional accessories: RB-RK3 1U rackmount kit


RB-LI2 - Stereo Line Isolation Unit

The inputs and outputs of the RB-LI2 stereo line isolation unit are connected together through a transformer, which has internal jumpers allowing the outputs to be balanced about ground. There is also a loop-through output, so that the RB-LI2 can be inserted into a line, forming a transformer balanced distribution point. This unit is useful where audio is required to be driven over a relatively long length of cable. By isolating the signal using transformers, ground loop currents that can be present in non-isolated signals, are eradicated completely.

Inputs: Two XLR 3-pin female, balanced. Outputs: Two XLR 3-pin male, balanced, isolated; two loop outputs, XLR 3-pin male.

Input impedance: >20 kohms. Frequency response: 10Hz to 36kHz +/- 0.5dB. Output impedance: 150 ohms. Distortion: 0.5% THD, 40Hz, +17dBu output. Common mode rejection: >64dB typically. Power source: 110-120V AC, or 220-240V AC, switchable, fused, 6W, filtered IEC inlet. Dimensions (WxDxH): 280 x 108 x 42mm. Weight: 1.0kg

Included accessories: Handbook, IEC supply cable with plug.
Optional accessories: RB-RK1, RB-RK2 1U rackmount kits.
