The sound module USM-RC-2 is the successor of our popular USM-RC sound and light module with improved and extended functions and applications. Both modules have been developed especially for RC model construction in order to equip models for land, air and sea with realistic and speed-dependent driving and engine sounds.

Due to the plenty adjustment and setting possibilities of the sound module USM-RC-2, each model can be individually and uniquely designed according to one's own ideas.

All setings are programmed with the software Sound-Teacher and saved on a micro SD card. The programm is only for Windows, with an emulator like WineBottler is is also possible to use the Sound-Teacher with a Mac or other operating systems.

Sound functions:
Driving noises sound very authentic due to detailed starting, stopping, idling, accelerating, running, braking and reversing sounds. To make model and surrounding noises perfect up to 30 additional sounds and 8 random sounds can be played next to engine sounds.

For an easy start we have more than 170 ready to use sound projects for various types of models. With the software "USM-RC-2 Sound-Teacher" (for Windows) you can create your own sound projects with individual sound, light and servo functions. On our DVD-ROM more than 700 different sound files are available for a variety of applications.

In addition you can edit your own sounds for your individual application with the included software "Audacity". With our software "USM-RC-2 Sound-Teacher" (for Windows) you can compile different sound and light functions.

The USM-RC-2 can play up to 4 sounds simultaneously. This means, additional to normal engine or driving sounds, up to three additional or random sounds can be played at the same time. All sounds have a quality of 44,1kHz and 16 bit.

The USM-RC-2 contains a powerful double amplifier (2x20W), therefore no additional amplifier is required, you only need to connect one or two loudspeakers for an optimal volume. We recommend the loudspeaker LS-4R-25W-90.

Due to a high number of running steps (internally up to 255) the speed-dependent driving and engine sound transitions are played smoothly without any steps or interruptions.

In order to adjust engine sounds to the corresponding driving speed, the pace (voltage) is measured either at the cruise control/drive motors (analogue and mix mode) or at the proportional channels of the receiver (digital mode).

In digital/mix mode you can easily connect the sound module with up to 4 servo patch cables to all commercially available RC-receiver.

With one-channel multi-function selection (EKMFA mode) it is possible to control up to 16 functions of the sound module with only one single proportional channel. This is very useful when you have only one proportional channel left.

The nautic mode is a further option to trigger functions of the USM-RC-2. For this mode the transmitter requires a suitable multiswitch (e.g. BEIER-Electronic Nautic-Multiswitch NMS-16-R, NMS-16-G, NMS-24-G, Graupner Nautic-Expert Modul Nr. 4108, Robbe Multi-Switch 16 Modul Nr. 8084).

Light functions:
The USM-RC-2 contains 12 switching outputs for connecting LEDs, lamps and relays. Different light effects (e.g. brake lights, indicators, hazard warning lights, machine-gun fire or flickering-lights) can be implemented at these outputs.

The switching outputs can be divided into 2 output groups. For these 2 groups you can define output sequences for example with moving lights, rotating lights or beacon lights for airplanes.

Movement functions:
For movements the USM-RC-2 offers 2 servo outputs, which can be used for various motion application combined with the matching sound.

Extra: Connection of a smoke generator:
With the sound module USM-RC-2 or the extension module EXM-2 a proportional smoke generator can be controlled speed dependend.

Depending on the driving situation the smoke generator is controlled in a different intensity and more or less smoke is produced. Additional setting options, such as smoke volume at start, while standing or at full speed the smoke can be adjusted in the Sound-Teacher.

The smoke generator is connected to the switching outputs X3 of the sound module. Heater and fan can be connected and controlled together and separately. The current consumption of the smoke generator must nor exceed 1,5 A at one sound module output and not 3 A in total (all switching outputs together).

A smoke generator with a current consumption of 8 A can be connected to the motor output of the extension module EXM-2.

Additional information can be found in the Operating Manual (PDF).

Customer reviews for this product

Carmine aus Tucson:

I am very pleased with the USM RC-2! Powerful Sound and many Sound and Light functions to choose from. The fact that it is nearly infinitely programmable by PC, adds value!

I am in the United States, and there is a fast growing following for your fine products. We REALLY need English Language Tutorials...
There's still many functions that I still have no idea how to use! Not all of us are fully Computer fluent. Particularly us OLDER People!!
Edward aus Kemptville:

I must say that knew nothing about your company here in Canada, until a friend told me about the sound modules you produce. I have since bought two of your USM-RC-2 sound modules for my model ships in the last month and I am extremely pleased with their performance and ease of programming.

I have will spread the word through our Model Boat Club and I am sure you will get much more business.
walter aus Mank:

Es ist nicht das erste Soundmodul, das ich von der Firma Beier habe und wird auch nicht das letzte sein. Top Qualität zu günstigen Preisen und immer verlässlich. Auch mit der Fachberatung kann eine andere Firma nicht mithalten. Die Firma hat immer ein offenes Ohr bei Wünschen oder Problemen.

Danke für Alles
Gert aus Ladenburg:

Ich habe alle Soundmodule mittlerweile auf das USM RC 2 umgestellt - ich bin immer noch begeistert von dem guten und Autentischem Klang - vielen Dank
Patrik aus Stadtbergen :

Hallo liebes Beier-Team,
Das USM RC 2 ist unglaublich gut und Euer Technischer Support ist noch besser!
Immer kompetent und immer eine Lösung vorhanden.
Das nächste Modul (SM-IR-16-2) ist schon gefunden und bald bestellt.
Ihr macht Freude am Modellbau!!
Andreas aus Gelsenkirchen :

Hallo Liebes Beier Team,
auch ich möchte mich einmal zum Sound Modul und dem Erweiterungsmodul äußern und Euch ein großes Lob aussprechen. Ich habe noch nie so ein super Modul mit so wahnsinnig vielen Möglichkeiten gehabt. Ich bin total begeistert. Mittlerweile habe ich 2 Soundmodule USM-RC2 und ein älteres USM RC1 im Einsatz. Ich einem meiner Modell habe ich zudem das Erweiterungsmodul. Es ist super. Nur weiter so. Die nächsten Soundmodule für meine Modell werde ich bald bestellen. Freue mich jetzt schon darauf Sie in Betrieb nehmen zu können.
Engin aus Mechernich:

Hallo Beier Team,
das ist mein erster Soundmodul von Beier und ich bin begeistert.
Einfach zu bedienen, alles funktioniert perfekt und die Akustik ist sensationell. Ab jetzt nur noch Beier Soundmodul in meie Schiffe.

Engin aus der Eifel
Sébastien aus namur:

Hallo Frau, Herr, vielen Dank für die Lieferung und die Geschenke, super gutes Material, vielen Dank
Lutz aus Forst:

Es ist immer Weihnachten, wenn das Paket von Beier eintrifft.
Diesmal sogar mit zusätzlicher kleiner Weihnachtsüberraschung.
Große Klasse - Daumen hoch - Frohes Fest.
Grüße aus der Lausitz
Stefan aus Beverungen :

Die Soundmodule von Beier sind einfach genial - ich kaufe sie immer wieder für meine Rc Panzer - sehr zu empfehlen.
