MrRCSound Version 4 Instructions
We have made every effort to make the MrRCSound Version 4 RC airplane sound system, the most
easy and versatile sound system on the market. Every effort has been made to make this the the most
hassle free system available. Designed for the average pilot, the unit has been pre-loaded with all the
sounds, tested to ensure each unit is functioning properly, and is easy to use.
Your sound module comes with at least one speaker and the Version 4 sound card. The sound card is
actually several different components in one. It consists of a Voltage Regulator, Sound module, and
amplifier. It has been specially designed to work best with the Max SPL2 speakers available at
MrRCSound.com. It is not recommended to use any other speakers.
The sound card can safely accept input from a 3S Lipo to an 8S Lipo, or approximately 12v -35v.
Connection to the main flight pack is recommended via a power Y cable or tapping off the main power
connector. Using a separate battery pack is also an option, but because of the extra weight it is not
recommended.
The sound unit, even with 2 speakers, has very low draw, especially compared to other sound units.
There is no need for high wattage and amp draw, when decent volume levels can be achieved with
higher efficiency. With 2 speakers the unit will never draw more than 1.75A and 25W.
Hooking up your Version 4:
Connection of the Version 4 is strait forward. There are 4 servo style connections on the board. These
accept Male to Male servo cables that go to your RX. These are labeled on the board “Servo 1-4”
Servo 1 is the the main engine sound connection. Servo 2-3-4 are used for auxiliary sounds such as
guns, whistles, and pilot chatter. Servo 1 connection can be made either to your throttle channel with a
servo Y cable with the other end going to your ESC, or to a separate channel you have mixed with the
throttle.
Connection of Servo 2-3-4 can be made to any empty RX channels that are associated with a switch.
Powering Up:
When powering up the Version 4 sound unit, it is recommended that you do not hook it's power up until
power to your RX is on. The Version 4 sound card detects your throttle position when connected and
uses that for it's start position. Since some RXs can take several seconds to initialize, it is important to
wait until the RX is ready, otherwise the Version 4 sound card may not see the proper starting throttle
position.
Once powered up, one to two clicks of the throttle stick will start the engine start up sequence. To
make these as realistic as possible, some of the start up sequences can be quite lengthy, upwards of 20
seconds. During the start up sound sequence, adjust the throttle position one more click up, or a couple
clicks up on the throttle trim. When the start up sound is done, it will enter an idle sound. The RPM
now will increase and decrease with throttle movement. Move the stick back to the start position to run
the shut down sound.
Sound Configurations:
The default Version 4 sound unit comes complete with 6 engine sounds. These include Lycoming,
Merlin, Continental, Daimler Benz 601, Pratt & Whitney Double Wasp, and a Generic Turbine. Each
sound configuration has 3 auxiliary sounds with it to complete the sound set. Servo 2 is ALWAYS a
machine gun sound, and is synced to the 2 LED outputs on the board. The main engine sound used
determines the auxiliary sounds on Servo3 and 4. For example, Lycoming, Continental or other
civilian engine sounds may have pilot chatter such as “clear”, “clear prop” or “contact”, while military
engines may have a second machine gun, cannon, whistle or other special sounds.
Sound configurations are changed by pressing the red button located on the board. You will hear what
configuration you are on by an audible “airplane one”, “airplane two”, etc. announcement. To
determine which configuration you are on, please review the configuration sheet.
Volume:
The volume knob is a yellow turn screw located on the board. This can be adjusted by a small Philips
screw driver. Just be careful not to contact any points on the board with the metal screw driver. The
volume knob is preset to full volume. Notice it looks like a + sign, and not tilted to the right. This is
the full volume point. Although it may be possible to turn the knob slightly more to the right, it is not
recommended, and will not increase the volume.
The system will work at full volume with either one or two speakers attached. You should never have
to move the volume down, unless you wish to, with one exception. On especially warm days, the
amplifier chip may get too warm and begin to cut the sound in and out. If this happens it may be
necessary to adjust the knob down in volume to about the ¾ mark.
