Aphex (RØDE) Model 124B / - New item!

The industry standard for connecting consumer and professional stereo audio equipment

• Enables the use of consumer equipment (-10 dBv) with professional (+4 or +8 dBm) systems.
• Two-way buffer to ensure consumer and professional systems operate correctly.
• Acts as a signal splitter, providing two high-quality balanced outputs via an unbalanced ‘Y’ connector.

A clean and reliable solution for bidirectional level and impedance matching.

The Aphex Model 124B Audio Level Interface is designed for use with -10dBV consumer hi-fi equipment and +4 or +8dBm professional/industrial/broadcast audio systems. It provides an extremely clean, reliable two-way buffer, allowing both systems to operate at maximum performance whilst matching impedances and operating levels.

Input:

Servo balancing means that high common-mode voltages, such as induced hum from a nearby AC power line, are compensated for to preserve headroom. The 100 kΩ input impedance allows a 600 Ω balanced or unbalanced line to be bridged with negligible loading effects. The switchable 600-ohm load on the front panel allows the input line to be terminated if required.

Outputs:

Thanks to servo balancing, the outputs can be used in either balanced or unbalanced (single-ended) mode at any time by simply grounding one of the unused pins. The servo compensates for the voltage drop on one side, so that no 6dB level loss occurs. The outputs are also protected against short circuits, so that nothing is damaged if the wrong pins are earthed. An indicator on the front panel flashes red when the balanced output level is 5 dB below clipping.

• Two-way interface amplifier for connecting any unbalanced devices such as a cassette deck, equaliser, CD player or DAT deck to the IHF inputs and outputs. The balanced inputs and outputs connect to a studio console, a patchbay or other line-level devices. The various gain levels and impedances are matched to ensure optimal performance.
• Line driver. The servo-balanced input and output stages of the 124 can be used as a highly effective line driver for long cables. The output stage provides a short-circuit-proof, low-impedance source that remains relatively unaffected by the cable’s impedance. The gain can even be used to boost the signal level. For this application, either the unbalanced IHF or the balanced high-level inputs can be used. In the latter case, the IHF inputs and outputs are simply bridged.
• Signal splitter. The 124 can be used to generate two high-quality balanced outputs from a single unbalanced mono signal. A Y-connector is used to split the incoming signal between each of the unbalanced IHF inputs.

Rackmount kit for 120B, 124B and 141B

Enables rack mounting of one or two ‘B’ series products in a single rack space. The new front panel design of the ‘B’ series products and the new rackmount kit design make installation 100% faster!
