MrRCSound ASPIRE Sound System
MrRCSound ASPIRE Sound System - MRS002
What are the changes from MrRCSound V4.1 to the ASPIRE?
A more powerful amplifier is being used. It is rated at 5X the power of the V4.1 amplifier, but it is being utilized at 2X the power of the V4.1 amplifier. This leaves overhead so the amplifier is not taxed, as well as staying within the safety limit of the TT-25 transducers. Using more of the amplifier ability in the future may be possible if design changes are made to the transducers.
The memory style has changed from a chip style to a Micro SD memory card. This allows for much greater space for larger sound files, and ease of use. The V4.1 memory was 8mb total for all 6 stock sounds. The ASPIRE sounds will be approximately 110mb per engine sound!
This allows for much higher quality (16 bit 44K CD quality), longer engine loops, and overall better performance.
The ASPIRE has an expansion port for a future "combat module".
Each engine sound will have multiple startups and shutdowns for that respective engine. Real engines always have some differences each time they start and shut down. Sometimes an extra cough, sputter, rev up, etc.. To attempt to recreate this the ASPIRE will randomly choose a startup and shutdown of the respective engine. Thus giving a semi unique experience each time you fly. Engine sounds can have up to 15 different startups and 10 different shutdowns for the ASPIRE to randomly choose from.
Automatic Whistle Trigger
Many aircraft have distinct whistle sounds, such as the P-51 or F4-U. The ASPIRE has a built in accelerometer, which will detect a pull out of a dive or hard turn, and automatically trigger the proper whistle sound. No need to trigger it manually as on the V4.1.
New Sound Rendering
MrRCSound has developed a completely new method for creating the engine sounds. It is a complex method which involves cross fading, speed and pitch changing and spectral morphing. Both the engine
idle and the high RPM are real recordings of the respective engine. The processing allows for a very realistic ramp up and down through the RPM range.
One of the optional AUX. channels on the ASPIRE will have the ability to randomly select sounds. Depending on the engine being used, these could be aircraft related sounds, ATC chatter, or Pilot chatter, such as "Enemy, 10 o'clock high!" Other Aux. channels will have things such as guns, bombs, etc.
The sound the APIRE delivers has a much higher quality sound, you will notice that there is much more bass tones, that give a better overall representation of the real engine.
Because of the new amplifier, the volume on most sounds is greater. Some sounds may sound significantly louder than those on the V4.1. Others may sound about the same, or even a little lower. This is perception because the sounds tend to have more bass, and fullness. Bass sounds tend to travel further however.
MrRCSound has intentionally chosen high RPM sounds with a lot of the actual prop noise. This gives a more realistic sound in flight. Like on a real aircraft, there is not much prop noise at idle. While throttling up through the RPM range you will being to hear increasing prop noise, just like you would hear with a real aircraft.
You can be assured the idle and upper RPM of each respective engine is taken from the real thing. The in between RPM range is rendered in a way which replicates the real RPM changes, giving an overall great effect.
WARNING - connecting the sound system backward can result in a damaged FMS ESC - please see: warning and directions for proper wiring.
The ASPIRE will come with 8 sounds stock, up 2 from the V4.1.
- Double Wasp
- Wright Cyclone
- BMW 810
- Wasp Jr.
Features of the TT-25 "speaker" (comes with 1 TT-25)
- Speaker weighs only 2.7oz - 3.1oz
- Only 2" diameter and 1" thick
- No need to cut holes in your plane
- Easy mounting inside the fuse
- No dead spots because you whole plane is the speaker
- Improved bass response over a standard speaker
- Rugged - no paper cone to damage in a crash
- 108db (max) at 1M sound output
Options: (click the spare parts tab to see all optional components)
- Additional speaker: The base unit speaker is good for planes 900mm to 1400mm. We recommend a second TT-25 speaker, which easily plugs into the base unit, for planes 1400mm to 1650mm.
- Base speaker: If you want to add some low tone base to you plane, you can add a Bass Transducer as opposed to an additional speaker.
- MrRCSound 6 LED Gun Light Set: This is a set of 6 bright orange 5mm LED lights that is pre-wired to plug into the MrRCSound V4.1 sound system.
- If your plane has a T-connector for the battery - we highly recommend our "pass through T connector" with a JST connector tap. This will allow you to power the MrRCsound ASPIRE using your flight battery.
