SONIFEX REDBOX DISTRIBUTION AMPLIFIERS

Housed in red-anodised aluminium cases with apertures for fixing screws, this range of rack mounting distribution amplifiers have been designed to properly distribute audio signals to varying outputs.

RB-DA6 Distribution Amplifier - XLR Connectors

A multi-function distribution amplifier offering either six-way stereo, dual six-way mono, or twelve-way mono operation. The front panel has a power indicator, two pre-set input gain controls and a recessed switch to select mono or stereo operation.

There are two inputs using 3-pin XLR connectors, which may be fed with dual mono sources or a single stereo source to feed six outputs. Alternatively, one mono input can be distributed to twelve outputs. All audio connections may be wired balanced, or unbalanced, without loss of level, for use with domestic equipment. Power is connected using an IEC inlet, which has an associated fuse and voltage selector switch. All connections are on the rear panel.

Input: +28dBu maximum, 20kohms, balanced. Common-mode rejection: Greater than 66dB. Gain: -8dB to +18dB, adjustable separately for each input. Response: 20Hz to 20kHz +/- 0.1dB. Distortion: 0.01% THD, 1kHz, +8dBu. Noise: -100dB, unity gain, +8dBu output. Output: +28dB maximum, 50 ohms, balanced. Power source: 110-120V or 220-240V AC 6W maximum, switchable, fused, IEC Inlet. Dimensions: 1U rack mounting, 108mm deep. Weight: 1.3kg.

Included accessories: Handbook and IEC AC power cable. UK 13A plug.
Optional accessories: RB-RK3 rack kit.

RB-DA6P Distribution Amplifier - Phoenix Connectors

Sharing the specifications and accessory set of the RB-DA6 audio distribution amplifier, this uses Neutrik 'Phoenix' style terminal connectors instead of XLR inputs and outputs. The rear is fitted with fourteen 3-pole connectors. Each DA is shipped with the mating connectors so that wires can be simply terminated using a small flat-blade screwdriver.

RB-DA6G Distribution Amplifier - XLR Connectors - Gain Trims

This variant has the specifications and functionality of the RB-DA6, however it has twelve separate output gain-adjustment trimmers on the front panel. Accessories as RB-DA6

RB-DA6R Distribution Amplifier - RJ45 Connectors

Again based on the RB-DA6 (see above), this design differs in the inputs available and the output connectors. The two balanced XLR connectors remain as inputs, wired in parallel with a single RJ45 connector carrying the two balanced signals. A push switch on the rear selects between either these balanced connections or a pair of RCA (phono) sockets, offering unbalanced inputs. The outputs are available from six RJ45 sockets, each carrying a pair of signals. All RJ45 connectors are wired to the 'StudioHub+' standard, and can be used to connect to other equipment or infrastructure using low-cost standard RJ45 patch cords.

Specifications and accessories: As RB-DA6, excepting the following. Input impedance: 10k ohms, unbalanced.

RB-DA6RG Distribution Amplifier - RJ45 Connectors - Gain Trims

This variant is identical to the RB-DA6R with the addition of individual output gain adjustment, instead of global stereo gain adjustment. It has twelve separate output gain-adjustment trimmers on the front panel.

RB-DA4x5 Distribution Amplifier/Mixer

This model has four mono 3-pin XLR inputs, and four groups of five outputs on 15-pin, male D-sub connectors. All inputs and outputs can be wired balanced, or unbalanced, without loss of level, for use with domestic equipment. Each output has a separate buffer amplifier so that loading or a short circuit on one output of a group does not affect the others.

Front panel has four, tri-colour LED audio presence indicators to show the input signals or the level of the output groups, selected by a single switch. A removable panel conceals four gain trimmers for inputs and four for output level. Miniature switches configure the internal routing; each of the four output groups is fed from a mix of the four input signals or a test tone signal.

Specification as RB-DA6 except the following. Power consumption: 9W maximum. Depth: 158mm. Weight: 1.6kg.

Included accessories: Handbook and IEC AC power cable. UK 13A plug.
Optional accessories: RB-RK3 rack kit.

RB-MS4x3 Distribution Amplifier

This passive ‘quad’ distribution amplifier has four mono microphone or line level (accessed by using a 30dB pad switch located on front facing panel) 3-pin XLR inputs, each with three 3-pin XLR outputs. Of the three outputs, the first is a direct link whist outputs 2 and 3 are isolated with optional ground lifts – activated via toggle switches on the front panel. The front panel also has a push switch for external +48V phantom power, with a red LED to indicate phantom power active, as well as the push switch for the 30dB pad. This is replicated across the four channels.

Powered via external +48V DC phantom power on 2.5mm socket. Dimensions (WxDxH): 480 x 108 x 42mm. Weight: 1.5kg.

Optional accessories: RB-RK3 rack kit.

RB-DDA6A – Digital AES/EBU format

For the distribution of digital audio data in AES/EBU format, the RB-DDA6A has a single 3-pin female XLR for the input and six 3-pin male XLR connectors for the outputs, all on the rear, where there is also an IEC power inlet, fuse and voltage selection switch. The front has an LED to indicate power. Mounting flanges at each side provide for mounting to flat surfaces or the DA may be rack mounted using optional accessory panels. It accepts input sample rates in the range of 30kHz - 100kHz, and bit rates of 16, 20 and 24 bits, so can be used for standard CD signal distribution as well as for high quality 24-bit 96kHz work

Inputs and outputs: 2V / 7V peak-to-peak, minimum / maximum, balanced, 110 ohms +/-20%, balanced. Sampling rates include: 32kHz, 44.1kHz, 48kHz, 64kHz, 88.2kHz and 96kHz. Power source: 110-120V or 220-240V AC, 6W maximum, switched, fused. Dimensions (WxDxH): 280 x 108 x 42mm. Weight: 0.95kg.
