1 volume control for sound modules from Servonaut with servo cable. 5kOhm linear.

Sound module for wheel loader and crawler SMR. Space-saving installation with 55x28x13 mm. Dynamic, situation-dependent sounds. 7,2 - 12V. 2 free reception channels required! Space-saving installationDynamic, situation-dependent soundsDynamic engine noise, hydraulics, starter, shutdown, horn, dynamic drive chainCan be controlled via two free receiver channelsNo additional battery required, can be powered directly from the drive batteryBattery voltage 7,2 to 12V NiCd/NiMH, loudspeaker from 8 ohmsMaximum output power 3 watts at 8 ohms at 7,2 VSmall, separate volume control ideal for hidden installation on the modelOptional sound control SM-EQ available as an accessoryDimensions in mm approx. 55 x 28 x 13Important: The SMR requires a transmitter with extensive mixing functions to control all functions - at least one free mixer on the sound output for each valve servo channel and, if necessary, another for pump control. Of course, the Servonaut HS12/HS16 meets this requirement, as do transmitters from Brixl, Blauzahn or ScaleART Commander. The SMR may not be usable or may only be usable to a limited extent with transmitters from model aircraft - be sure to check beforehand!

1 excavator sound module SMB with speed and work-specific engine noises. Compressed air noise, horn/honk, starting, stopping. 7,2-12V 3 watts at 8 ohms. 2 free reception channels required! -dynamic, situation-dependent noises - engine noise, hydraulics, starter, shutdown, horn, drive chains, superstructure gearbox - can be controlled via 2 free reception channels - no additional battery necessary, supply directly from the driving battery - battery voltage 7,2-12V (10-cell NiMH), loudspeaker from 8 ohms - maximum output power 3 watts at 8 ohms at 7,2 V - small separate volume controls, ideal for hidden mounting on the model - optional tone control SM-EQ available as an accessory Dimensions: 55x28x13mm The SMB requires a transmitter with extensive mixing functions to control all functions - at least. a free mixer per servo channel (sound output). This is of course fulfilled by the Servonaut HS12 as well as transmitters from Brixl, Blauzahn or ScaleART Commander. The SMB cannot be used with transmitters from model aircraft or can only be used to a limited extent - be sure to check beforehand!
