Glensound GS-TRRS/X3 - Mono Audio Interface For Three Mobile Phones

The GS-TRRS X3 (Glensound-Mobile Phone Interface-Tip Ring Ring Sleeve) is a professional broadcast audio interface for connecting devices such as mobile phones to broadcast equipment via the devices analogue headphone/ microphone jack socket.

Each of the 3 interfaces converts a line level output from your broadcast equipment to a microphone circuit for providing audio to your mobile phone, while simultaneously taking the headphone output of your mobile phone and converting it to balanced line level outputs for interfacing to your broadcast equipment. The stereo signal from the TRRS device is summed to mono.

Easy to use front panel level controls for adjusting levels between the phone and your broadcast device, and professional audio quality makes this unit ideal for use in busy news rooms and studios.

Works With Apple and Android Phones
Apple and some Android phones have different wiring standards of the 4 pin 3.5mm TRRS headset jack. A simple to use and clearly labelled front panel switch makes it very quick and easy for the user to select which of the 2 wiring standards needs to be selected for interfacing to their phone.

Balanced Audio Connections
For complete versatility of interfacing to all types of audio broadcast equipment balanced bi-directional stereo audio circuits are provided.

Front Panel PPM and Level Control For Audio From Phone
Although the audio levels from recordings on mobile phones should be at fairly consistent levels between tracks in reality there is often a wide range of audio levels that need to be dealt with. Therefore an easy to view front panel level meter (PPM style) is provided to give a quick clear reference to the outgoing audio level from the phone. Conveniently located next to the meter is a level control providing a means for the operator to adjust the audio to a suitable level.

Level Control For Audio To Phone
To help provide a crystal clear audio signal to the operator's mobile phone a front panel wide range level control is provided to allow the user to adjust the level between the output of the broadcast device and the input of the phone.

Mains and DC Powered
For maximum flexibility and reliability the GS-TRRS X3 can be powered from mains (100 - 240 VAC) or an external DC (+/-12V) DC input. If both power sources are connected then they operate to provide redundancy on the power supply.

Front Panel and Rear Panel Phone Connections
With each module there is a 4 pin TRRS (tip ring ring sleeve) jack socket on the front and rear panel for audio connectivity to the mobile phone. The front panel socket makes it easy for the operator to see what is connected and the rear panel is perfect for a studio that needs a permanent interface solution.

Simple To Use
The GS-TRRS was originally designed for the specific requirements of one of our customers and in particular their requirement was to make the device easy and intuitive to use for journalists.
