    3. The SPKR terminals MUST NOT be connected to anything other than the appropriate loudspeaker for the supply voltage used. 4. The ShockWave 2 sound module receives its power from the receiver battery through the throttle cable. The ESC (without a BEC) can be connected to the right-hand set of THTTL1 pins to receive its signal from the receiver, thus avoiding the necessity of a Y servo lead to connect both the ESC and the sound module to the receiver throttle output.

    APPLYING POWER TO THE SHOCKWAVE 2 SOUND MODULE The ShockWave 2 module’s low-level circuitry can be powered using two methods. 1. From the R/C receiver through the THTTL1/2 or SOUND1/2 cables. 2. From the USB port when connected to a PC.

    2.4GHz receivers. If your receiver stabilizes much faster, you can reduce this wait time down to as short as one second using the SFXPC4.1.3 Software in its Control Panel->Hardware Tab. ShockWave2-4.1.3 Hardware Manual Page 8 of 40 Published: November, 2018 © Model Sounds Inc.

  • Page 10: Chapter 2 - The Microsd Card And .Sfx7 Files

    THE SHOCKWAVE 2 SOUND MODULE AND ITS MICROSD CARD The ShockWave 2 microSD Card connector is a push-push type, i.e. you push the card in to insert and lock it and push it again to release the card for removal. When inserting the microSD Card, make sure it is pushed fully home so that the latching mechanism prevents it from accidentally being removed.

  • Page 11: File Structure On The Shockwave 2 Microsd Card

    FILE STRUCTURE ON THE SHOCKWAVE 2 MICROSD CARD The files on the ShockWave 2 microSD Card must be in a certain format and structure. In the microSD Card Root Folder there is the following file : SELECT_YOUR_SOUNDSET_HERE.txt. This file should contain two lines as follows: One line naming the folder containing the .sfx7 file you wish to use.

  • Page 12: Chapter 3 - Connecting The Shockwave 2 Module To Your Pc

    CHAPTER 3 – CONNECTING THE SHOCKWAVE 2 MODULE TO YOUR PC You DO NOT need to connect the ShockWave 2 sound module to a PC in order to use it or set it up – it is fully configured and ready to use when you receive it. If you want to change any of its many configurable settings or change the sounds then you will need to connect it to a PC and install the optional SFXPC4.1.3 Windows only software application.

  • Page 13: Transferring Files Between The Pc And The Shockwave 2 Sound Module

    The ShockWave 2 module conforms to the USB2.0 Full Speed (12MBits/sec) specification. If you save files to the microSD Card whilst it is in the ShockWave 2 module, it will be much slower than when the microSD Card is in the USB card reader which conforms to USB 2.0 High Speed (480MBits/sec) specification.

  • Page 14: Chapter 4 - How To Wire The Shockwave 2 Module

    CHAPTER 4 – HOW TO WIRE THE SHOCKWAVE 2 MODULE WIRING FOR ONE THROTTLE WITH RECEIVER BATTERY Although some modellers favour using their ESC BEC (Battery Eliminator Circuit) to power their receiver, we do not recommend that set-up for high power systems. Depending upon the wiring, currents involved, and the quality of the ESC BEC, it can introduce radio interference on the receiver power leads.

    In all cases, please heed the notes (4) on page 5 regarding using the right hand THTTL pins to feed the ESCs only, not the other way round. Wiring diagram on next page … ShockWave2-4.1.3 Hardware Manual Page 14 of 40 Published: November, 2018 © Model Sounds Inc.

  • Page 16: Figure 4: Wiring For Separate Receiver Battery And Separate Sound Module Battery

    This arrangement is also recommended whenever the motor has a very high current draw so as to isolate the sound system from the spiky, interference prone motor wiring. ShockWave2-4.1.3 Hardware Manual Page 15 of 40 Published: November, 2018 © Model Sounds Inc.

    ShockWave 2 module and its loudspeakers. This means that you need all four loudspeakers to be pushing or pulling air at the same time. It would not help if the ShockWave 2 speakers (or exciters) were pushing air while the external amplifier speakers were pulling air, as they would be fighting against each other to produce the sound.

  • Page 20: Chapter 6 - Calibrating The Shockwave 3 Throttle Inputs

    The ShockWave 2 module makes this job easy for the average user by measuring the incoming throttle pulse width at the time the red/green LEDS stop flashing and using that as the neutral or OFF throttle pulse.

The green LED will flash TWICE to indicate that Throttle2 neutral or OFF position has been captured. ShockWave2-4.1.3 Hardware Manual Page 20 of 40 Published: November, 2018 © Model Sounds Inc.

    THROTTLE CONTROLS The ShockWave 2 module can be used with either a forward only throttle (for model airplanes or helicopters) or a forward and reverse throttle (for model boats, tanks and trains). This mode is automatically selected and stored during the Throttle1/2 Setup phase (see next).

    This can be set in the SFXPC4 Windows Application Control Panel->Hardware Tab as detailed in the SFXPC4SWManual.pdf document in the Manuals folder on the microSD Card. ShockWave2-4.1.3 Hardware Manual Page 24 of 40 Published: November, 2018 © Model Sounds Inc.

    The Analog input voltage can exceed 2.2V, and can accept up to +12Volts relative to GND, but only the first 2.2V portion will be of use, as that voltage is mapped to an "equivalent maximum pulse width" of 2000µs.

  • Page 31: Chapter 9 - Which Loudspeakers To Use

    It is permissible to use to use two 4 Ohm speakers in series only, not in parallel. This will allow the ShockWave 2 sound module to be used on a 6S LiPo where it will be able to deliver its maximum output power.

  • Page 32: Chapter 10 - How To Use The Led Switched Outputs

    LEDs are flashing. The LEDs may be supplied by the same receiver power that supplies the ShockWave 2 module, or another positive voltage up to the maximum 30V rating. These switched outputs are rated at 1 Amp maximum each or 4 Amps for all switched outputs together.

  • Page 33: Using Optional Separate Battery To Power Leds

    If using the receiver battery, connect the switched loads or LEDs to H2 pin 2 or 5 on the module which carries the receiver battery voltage. The LEDS MUST HAVE A SERIES RESISTOR (EACH) TO LIMIT THEIR CURRENT – see the article LEDSeriesResistors.pdf in the Articles folder on the ShockWave 2 microSD Card.

  • Page 34: Caution - Do Not Use These Outputs To Drive A Motor Directly

    NOTE: these diodes must be wired with very short leads directly across the switched outputs – see this photo – this photo is for the ShockWave 2 module, not the older Shockwave/SFX7.0 module. The diode’s action will not be effective if you use long wire lengths.

    UPDATING THE FIRMWARE IN THE SHOCKWAVE 2 MODULE Firmware is the program code that runs in the processor chip on the ShockWave 2 module. The ShockWave 2 module features a microSD Card Bootloader program that is a separate small program that runs in a protected area of the microcontroller’s FLASH program memory.

    The firmware has halted, i.e. has steady “crashed”. The sound module is inoperable until re-powered up. May also mean low receiver battery voltage – check battery voltage. ShockWave2-4.1.3 Hardware Manual Page 36 of 40 Published: November, 2018 © Model Sounds Inc.

  • Page 38: Where Are Hardware Settings Stored

    By default, hardware mode settings, except those above, are stored in a special section of the .sfx7 file that the ShockWave 2 module opened when it was powered up. That is convenient if you want the hardware settings to travel along with the sounds.
