General Installation Instructions
To prevent damage to the unit/module and possible injury, read this manual carefully and follow all installation instructions. This product has been checked for proper function prior to shipping and is guaranteed against manufacturing defects.
Before starting installation: Disconnect the battery's negative terminal and all cables from the device to prevent damage to the unit/module, fire, and/or risk of injury. For proper performance and full warranty coverage, it is strongly recommended to have this product installed by an authorized HELIX / MATCH dealer.
Install the Extension Card only in the designated device and its specific slot. Using the module in other devices or slots can result in damage to the Extension Card, the device, the head unit/radio, or other connected devices.
Technical Data
- Input voltage highlevel: 1.5 - 30 Volts (adjustable)
- Input voltage lowlevel: 0.5 - 8 Volts (adjustable)
- Lowlevel input: 3.5 mm jack
- Additional features: ADEP.3, Auto Remote function
INFO LED Status Information
- Green: Lowlevel input used (regardless of the Load Jumper)
- Orange: Highlevel input used & Load jumper removed OR Highlevel input used & Load Jumper installed
Mounting Information
- Disconnect all cables from the device.
- Depending on the device, there are two possibilities to access the Extension Card slot:
- Bottom plate is bolted: Untighten the screws of the bottom plate and remove it. Afterwards, dismantle the appropriate side panel by removing its screws.
- Bottom plate is not bolted: Dismantle the appropriate side panel by removing its screws and pull out the bottom plate sideways.
- IMPORTANT: Adapt the input sensitivity and the input load to the connected signal source. The factory setting of the input sensitivity (11 V / 3.5 V) is appropriate for most common radios. If the signal source connected to the highlevel inputs provides an input voltage between 11 V and 30 V (e.g., an OEM amplifier), the Load Jumper must be removed immediately, and the Input Sensitivity switch must be set to the 30 V / 8 V position. If unsure about the signal source's output voltage, contact your HELIX / MATCH specialist dealer.
Input Sensitivity Settings:
| Input Sensitivity | Load Jumper Configuration |
|---|---|
| 11 V / 3.5 V | Jumper installed |
| 30 V / 8 V | Jumper removed |
Important notice: It is mandatory to check the configuration of the Load Jumper before the first use, otherwise, severe damage to the ANALOG IN module could occur. The position is also indicated in the DSP PC-Tool software.
- If the highlevel input is used as the primary and only highlevel input, the automatic turn-on function can be activated (Auto Remote = On). This function turns the entire device on and off together with the signal source. Note: The automatic turn-on feature is deactivated ex works (Auto Remote = Off). As soon as a signal source is solely connected to the module's stereo line input, it is mandatory to connect the remote input of the device to power up the amplifier / DSP.
- Insert the Extension Card into the specific slot of the device, marked in the following picture (the picture representatively displays the Extension Card slot of the MATCH UP 7DSP). The exact position of the slot can be found in the manual of each device.
Module Installation and Connection
- Ensure the module is installed properly and all pins are fully inserted into the socket.
- If the bottom plate was bolted, fix the new side panel delivered with the Extension Card. Afterwards, reinsert and fix the bottom plate. Otherwise, reinsert the bottom plate first and then fix the new side panel with screws.
- Reconnect the power supply and ground cable to the device.
- Connect the amplifier / DSP to your computer. For longer distances, use an active USB extension cable with an integrated repeater or the optionally available WIFI CONTROL interface.
- Turn on the device first, then start the latest software or at least software version 4.61a. The Extension Card is automatically detected.
- IMPORTANT: After rough adjustment of input sensitivity and input load (see point 3), fine-tune the input sensitivity in the DCM menu of the DSP PC-Tool software by following these steps:
- Open the "Extended Features" tab of the DCM menu.
- Select the configured Input Sensitivity Switch Position of your module.
- Adjust the input sensitivity to match the output voltage of the connected signal source.
Signal Routing
The inputs can be freely configured as additional MAIN Inputs or as an AUX source. Route the "AUX L" and "AUX R" signals in the "Main Routing" tab or in the "AUX / HEC Routing" tab.
The "Used Input" window automatically indicates which input is connected. For the highlevel input, it also shows the Load Jumper status. The used input influences the adjustable range of the "Input Gain" configuration.
Signal Routing Example (DSP PC-Tool):
The diagram shows routing options for Analog, AUX/HEC, and Digital inputs, allowing flexible configuration of main inputs and AUX sources.
Input & Output Configuration Example (DSP PC-Tool):
The diagram illustrates the configuration of various inputs (e.g., AUX L, AUX R, Front L, Front R) and their respective signal routing percentages.
Input Gain Adjustment:
Adjust the input sensitivity to match the output of the connected signal source. The "Used Input" window automatically detects the connected input and Load Jumper state. It may be necessary to manually adjust the ADEP.3 Compatibility Mode.
ADEP.3 Compatibility Mode:
This mode covers two specific cases: Class AB Head Unit compatibility (e.g., VAG devices) and Single Ended Power Amplifier.
Warranty Disclaimer
The limited warranty complies with legal regulations. Failures or damages caused by overload or improper use are not covered by the warranty. Please return the defective product only with a valid proof of purchase and a detailed malfunction description. Technical specifications are subject to change! Errors are reserved!
