Soundunits Audioamplifiers Smokegenerators Electronic Switch Servocontroller
1. Sound units
All offered digital sound units are reproducing original
engine- and special sounds. The engine range covers starting, engine idle, reeving up the engine, acceleration, speed dependent engine sound, returning to idle state and engine shut down. Available special sounds are horns, flaps, weapons, radio messages, depending on the kind of sound unit.
Up to two speed signals can be scanned directely at the receiver to determine the moving state of the model. This makes it ideal for tracked vehicles.
It can be used in combination with burshless
or common DC motors.
To ensure maximum output power at large scale vehicles, a external amplifier is used. You can use car HiFi components as well as tiny SMD amplifiers. Different amplifiers are on stock.
Universal digital outputs can start actions depending on the played sound, like muzzle flashing LEDs or motors to move something in the model.
A fully dynamic and sound synchronous working smoke generator for exhaust simulation is also available.
The following control modes are possible:
This rotary switch / push button combination must be connected at a spare proportional channel of your transmitter.
For mechanical installatioin already present extension places of your TX can be used usually. (Only two wholes are necessary)
The desired sound is selcted by one of the 12 rotary switch position and triggerd by the push button.
This allows a convenient, quick and direct sound selction.
In principal the encoder is a simple potentiometer with 12 fix positions.
B: Direct control by a spare proportional channel of your radio
A common proportional channel, equipped with a 3-position switch at your TX can be used to control the soundunit.
This switch should have a neutral position and momentary contacts to both sides. Permanent switching is also possible, in case the switch is centered manually.
Control mode â€śIndirect Soundselectionâ€ť
The desired sound is selected by flicking the switch x-time up (according to the desired sound number).
The selected sound is triggered by flicking the switch down.
A already selected sound can be triggerd multiple times without a new selection (f.e. MG bursts).
This mode allows triggering all sounds and functions loaded at the unit.
Control mode â€śDirect Soundselectionâ€ť
The desired sound is simply selected by flicking the switch up (sound1) or down (sound2)
Control mode â€śAutostartâ€ť
This mode does not need any control channel. Fist acceleration of the motor starts the engine. If it runs 20s idel, it is shut down automatically.
This control mode does NOT offer any special sounds(f.e. horn).
For installing the soundsystem in your model, common RC-modelling solder skills are necessary. The offered componets are parts of a soundsystem, created by the customer.
Please see the manuals for further descriptions.

2. Audio Amplifiers
2 x 40W power amplifier (at 12V, 2Ohm speaker, 10% THD)
This universal NF amplifier can be combined with all soundunits. It is delivered in shrinked plastic tube, with a already
installed mounting rail. Installation on a metallic surface or in a airstream is recommended to get additional cooling.
Power supply range: 9-18V
2x40W amplifier manual Price: 49 â‚¬
4x40W power amplifier (at 14V, 2Ohm speaker, 10% THD)
This high power amplifier can be combined with all Benedini Soundunits. It has a internal â€śmax volumeâ€ť indication.
This means the volume can be increased until the LED starts flashing. Of course this requires speakers with a according power rating. The combination with our R10S or SPH-30 speakers is ideal.
The amplifier can be operated with 1-4 speakers:
Speakers Nr.1+2 are connected by the main plug, speakers Nr.3+4 by solder pads at the bottom of the PCB.
Using a 4S LiPo power supply is ideal. 3S supply is possible. The capacity depends of the number of speakers. For 30min flight and two R10S speakers, about 1500 mAh are recommended.
This high power amplifier needs sufficient cooling. It MUST be mounted in a well ventilated area of the plane (airstream) !
Power supply range: 9-18V
4x40W amplifier manual (PDF) Price: 59 Euro
50W power amplifier (at 45V, 8 Ohm)
This amplifier is ideal for electric airplane applications. It can be powered directely from the main batteries.
It is delivered in shrinked plastic tube, with a already installed mounting rail. Installation on a metallic surface or in a airstream is absolutely necessary to get additional cooling!
Power supply range: 24-50V
50W/50V amplifier manual Price: 79 â‚¬

â€śSmokeâ€ť generator operating with WATER
This new â€śsmokegeneratorâ€ť for exhaust simulation can be combined with the TBS5 and TBS Light II soundunits.
The used medium is WATER and no smoke oil. The â€śsmokeâ€ť is generated by a ultrasonic water evaporator.
The functionality is similar to our well known oil based smoke generator. Smoke volume and speed at the exhaust is adjusted to the model state.
It is delivered as a â€śmachanic kitâ€ť with a prebuild and tested controller and all necessary components beside the watercontainer itself. Any plastic food container can be used and sourced locally.
This allows the modeller to select the right size meeting the space condition in each particular model.

Smoke generator operating with SMOKE OIL
This option realizes an absolute realistic exhaust simulation. Smoke volume and smoke speed depends on the model
state. When the engine is shut down, no smoke exits the exhaust. During starting the engine, a large volume of smoke is blown out the exhaust.
This smoke generator is delivered as a kit, with already prebuild electronic.

4. Electronic switching unit
The TBS Switch is based on the TBS Mini soundunit.
It is fully configurable by the TBS Flash software (Download)
6 outputs are provided, handling up to 12V / 0,5 A each.
If you have already a encoder (see above) installed at your TX to control one of my soundunits, the remaining not used encoder positions can be used to control this device.
Price: 69 Euro Wireset: 5 Euro
In combination with this servo electronic, any DC gear-motor (like car wiper- or window lifter motor) can be used to build your own high power servo.
A potentiometer must be mechanically connected at the output shaft for position feedback.
