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.
