Description
The TX-AFC1F is a connectorized balanced-to-unbalanced audio transformer designed to convert professional line-level signals to consumer phono-level outputs. It provides galvanic isolation and studio-grade bifilar transformer construction to preserve signal integrity. The compact design simplifies level matching and isolation in live sound, studio and broadcast chains.
Key features include a studio quality bifilar audio transformer, gold-plated contacts on both input and output, and reliable galvanic isolation. The unit performs balanced to unbalanced conversion and professional to consumer level translation with minimal signal corruption. Connectorized XLR input and phono jack output reduce installation time and maintain consistent connections.
Performance is specified for a flat frequency response from 20 Hz to 20 kHz +/-0.1 dB to ensure accurate audio reproduction across the audible range. Distortion is extremely low with THD below 0.06% from 50 Hz to 20 kHz at +4 dBu and a typical 0.0015% at 1 kHz with +4 dBu input. Common-mode rejection exceeds 85 dB at 50 to 60 Hz and the input supports +4 dBu nominal levels up to +22 dBu maximum.
Connectivity is straightforward with a balanced XLR input and an unbalanced phono jack RCA output, both using gold contacts for reliable mating. The input is bridged at 2.5 kO and the output provides a -10 dBV consumer level signal for direct compatibility with consumer equipment. These interfaces make the TX-AFC1F compatible with consoles, outboard processors, recorders and playback devices.
Typical applications include converting console or outboard balanced feeds to consumer devices, isolating signal grounds to eliminate hum and noise in broadcast facilities, and interfacing professional sources with consumer-grade recorders or amplifiers. It is well suited to live sound, post production racks and installed audio systems where ground loops or level mismatches occur. The galvanic isolation helps protect downstream equipment and maintain clean signal paths.
Installation requires no special tools beyond standard cabling due to the unit’s connectorized design and standard XLR/RCA interfaces. The TX-AFC1F operates in ambient temperatures from 0 C to 55 C and ships in a compact cardboard package. Robust construction and gold contacts provide durable, long-term performance in professional environments.
