Audio Signal Convertors

RDL TX-1W Music on Hold Amp - 1 Watt Features: Feed Audio into Telephone Equipment Music-on-Hold Input Adjustable Audio Level Optimized Sound Quality Unbalanced Output, up to 1 Watt Balanced Transformer driver Output Ultra Compact Size The TX-1W is the ideal choice in on-site installations where the central telephone switching unit needs to be fed with music, voice or combined music/voice signals. There is a wide variety of telephone instruments in use. When a caller is placed on hold, the audio quality perceived is affected by the caller's own telephone, as well as the telephone lines, central switch and on-site equipment. Due to these variations, conventional audio amplifiers used as music-on-hold drivers frequently produce annoying artifacts at the caller's earpiece. Attempts to reduce listener fatigue through high-frequency rolloff alone tend to produce a muffled, tired sound. The TX-1W features a spectral response specifically characterized to match the broadest variations in telephone audio distribution, producing a lively, crisp, interesting sound without the annoying resonances and distortions prone to creating listener fatigue.

Radio Design Labs ST-UMX3, 3x1 Universal Audio Mixer - 3 Microphone or Line Inputs x 1 Microphone or Line Output   Features: Audio Mixing with Up To Three Inputs Switch-Selectable Mic or Line Inputs Switch-Selectable Mic or Line Output Add Additional Microphone or Line Level Inputs to an Existing Mixer Combine Signals of Different Level, Impedance, or Balanced /Unbalanced Configuration The ST-UMX3 is a three-channel audio mixer for combining mic-level or line-level signals to a single output. A MIC/LINE switch is provided for each input. A separate MIC/ LINE switch selects the output level. Each input features a separate preamplifier circuit, which isolates it from the other inputs. An audio taper single turn gain adjustment is provided for each of the three input preamps. Signals from the three preamps are actively summed and fed to the output amplifier which includes an RDL® dual-LED VU meter. Each input level is set while observing the LED output level meter. The dual-LED output meter follows standard VU ballistics. The intensity of the green LED progresses from minimum at -11 dBu to full intensity at +4 dBu. The flexibility of switching each input and the output between MIC or LINE allows installers to address a wide variety of mixing solutions with only one product type.

Hosa DIB‑443 Sidekick Passive DI Box Product Overview The Hosa DIB‑443 Sidekick Passive DI Box is a compact, no‑power‑required device that allows you to connect guitars, basses, keyboards, and other mono instruments directly to a mixer or audio interface via XLR, while converting the high-impedance unbalanced signal to a low-impedance balanced signal. This DI box is ideal for live sound, studio, and rehearsal environments where a clean, interference-resistant signal path is critical. Key Features & Specifications Feature Specification / Description Type Passive DI (no battery or active electronics) Input 1 × ¼″ TS (instrument) Output 1 × XLR (male, balanced) Additional Output ¼″ parallel “thru” or instrument output (for sending to amp) Ground Lift Switch Yes (to help eliminate hum/ground loops) Inst / Line Switch Allows choosing whether the input is treated as instrument-level or line-level Frequency Response Flat response from < 10 Hz to > 20 kHz Construction Rugged metal housing for stage / mobile use Warranty Covered under Hosa’s standard warranty terms Why Use It & Benefits for Installers / Musicians Noise & Interference RejectionThe isolation transformer helps eliminate hum and interference (especially over long cable runs) by decoupling ground loops. Signal MatchingConverts high‑impedance unbalanced instrument signals into low‑impedance balanced signals suitable for long cable runs to mixers or audio interfaces, preserving signal integrity. Flexible RoutingThe parallel ¼″ output lets you continue to drive your amp while sending the balanced XLR feed to the console or recording system without needing extra splitting gear. Zero Power RequiredBecause it’s passive, there’s no need for phantom power or batteries, reducing setup complexity and failure points. Compact & RuggedIts sturdy housing and small footprint make it easy to integrate into pedalboards, rack systems, or mobile rigs. Example Installation / Usage Scenario Imagine you’re on stage with a guitar and an amp. You want to send your signal to the house PA while still driving your amp locally. You connect your guitar → DIB‑443 input (¼″ TS) → amp input, and also send the DIB‑443’s XLR output to the mixing console’s channel. The ground lift switch helps reduce hum or buzz if you notice ground loop noise. Because the DIB‑443 is passive, you never need to worry about batteries running out mid‑gig. In a recording setup, you could place the DIB‑443 between your instrument and the preamp or audio interface, letting you keep cables quiet and signal clean for capture. Tri‑Tek Electronics as Your Distributor Tri‑Tek Electronics is an authorized distributor for Hosa products.
