Let's delve into the exciting world of eurorack synthesis with the Boredbrain Music Xport, an ultra-compact balanced audio output module. Designed specifically for synthesizer enthusiasts and professionals, this module unlocks the power of balanced audio in your eurorack set-up, bringing professional sound quality to your rig with the click of a button.
The Xport sets itself apart with its ability to convert eurorack audio to professional balanced line-level signals. Balanced audio is a fundamental requirement in professional audio applications, owing to its unparalleled noise rejection capabilities, particularly in long cable runs. These are often used with pro-grade interfaces, mixers, patchbays, and live sound equipment.
Implementing high-performance balanced line driver ICs over the traditionally larger isolation transformers, the Xport efficiently facilitates six channels through ¼-inch TRS jacks, labelled OUT 1-6. These output differential signals scaled to +4 dBu are capable of driving long cable runs loaded with high capacitance.
Here's the art! The core of noise rejection lies in balanced or differential signals. Each audio signal output witnesses the birth of its duplicate but with an inverted polarity. This duo-summoned original signal (SIGNAL +) and its inverted clone (SIGNAL -) are transmitted via a TRS cable, with SIGNAL + aligning with the tip (T) and SIGNAL - pairing with the ring (R). The twin transport within the cable ensures uniform noise if it's picked up across the cable. The sophisticated reversal of inversion at the balanced input combines these two signals and spurs a phase cancellation in the uniformly acquired noise. So, no hindrance — just clean and clear FINAL SIGNAL!
Despite housing six channels within the sleek 6 HP layout, signal integrity is no compromised. The meticulous construction of Xport allows the absolute isolation of all channel circuitry to erase any chances of crosstalk or channel "bleed." Each channel circuit operates with its own 0 V (ground) reference running independently towards the primary power connector.
Your audio inputs, IN 1-6, gladly accept eurorack level audio signals in the ±5 V (10 Vpp) range. Post the removal of DC-offset; these signals are thoughtfully buffered and scaled down before touching base with the balanced line drivers.
Making your interaction utterly transparent and user-friendly, the dynamic signal level of each channel is visually represented by the GREEN LED. If the RED PK (peak) LED lights up, it indicates a +6 dBu reach by the output signal.
In the vibrant world of eurorack modules, the Boredbrain Music Xport brings pro audio applications home. Providing unparalleled noise rejection and signal integrity, this compact module is a power-packed performer offering isolated channel circuitry and high capacitive drive. If you aim for noise-free, superior sound quality, it's time to plug-and-play with the Xport and ascend to your next music level.
