Product Research

Overview: The MATCH UP 7BMW is an add-on amplifier and sound processor, designed to easily install into compatible BMWs with the (Option 676) HiFi sound system, offering more power and dynamics over the factory system. The included adapter harness and mounting bracket allow the amplifier to be mounted in the factory amp location, utilizing the existing amp wiring harness, and can even be hardwired in other BMWs where the adapter harness won't work.

DSP: Configuration of the cutting-edge 64 bit DSP in the UP 7BMW processor is straightforward and intuitive using the DSP PC-Tool V4 software, that's downloadable from Audiotec/Fischer's web site (compatible with all Windows operating systems from XP through 10, MAC not supported). The unit features 4 main input channels and an optical input. An Auxiliary Input is also available via an optional MATCH Auxiliary Extension Card Slot (MEC slot) sold separately. All of the inputs are freely configurable to any of the 8 output channels: (2) Front, (2) Rear, (2) Subwoofer, (1) Center, and (1) Line Out. The 5 sections of the DSP PC-Tool include the following:

• Main: The Main screen, of the DSP PC-Tool, allows you to modify each input with its own 30-band graphic and/or parametric EQ along with both high- and low-pass filters. Filter types include: Butterworth, Bessel, Tschebychev, Linkwitz, and Self-Defined, with available slopes in 6, 12, 18, 24, 30, 36, and 42 db/octave. Other Main options include quick adjustments for Phase, Polarity, and Time alignment and the ability to mute any of the outputs.
• DCM: This screen lets you activate and configure an optional wired remote, such as the Director or URC.3 (sold separately). Buttons on the remote can be assigned different functions from this screen and also include options for adjusting the Signal Detection Sensitivity for the Main, Digital, and MEC Aux input sources.
• FX Menu: The UP 7BMW offers FX processing that's specific for each output section: Front, Center, and Augmented Bass.
  • Front Processing: includes StageXpander, which enlarges the sound stage of the front speakers for a wider stereo panorama, and ClarityXpander, which improves the high frequency response for crisper and clearer highs.
  • Center Processing: includes RealCenter, which emphasizes the mono information from the left and right channels, and ClarityXpander which improves the high frequency response.
  • Augmented Bass Processing: Includes Dynamic Bass Enhancement, which extends boosts the deep bass response in relation to the overall volume, and SubXpander, which adds subharmonic tones to the fundamental bass for an ultra-deep bass response.
• I/O: The Input and Output Configuration screen lets you assign any of the analog, digital, and aux inputs to any of the output channels by simply dragging-and-dropping the icons. Input channels can have 5 bands of either Graphic Shelf EQ or Parametric EQ applied along with Time Delay that's independent for both left and right channels.
• Time: This page lets you adjust the Phase and Polarity of each input channel as well as setting the distance, in either inches, centimeters, or milliseconds, for the Time Delay. Here, output channels can also be Muted.
• RTA: The UP 7BMW includes a built-in RTA (Real-Time Analyzer) that can give you a visual representation of the frequency response inside your vehicle.

Class HD Technology: The UP 7BMW combines the efficiency of a Class H amplifier with the principle of a Class D amp. The result is an unsurpassed efficiency that easily outperforms any conventional Class D amplifier. By varying the internal supply voltage based on the amplitude of the input signals, idle losses are significantly reduced and overall efficiency is close to maximum at any time.

Advanced Diagnostics Error Protection, 3rd Generation (ADEP.3): The amplifier utilizes a new ADEP circuit to allow the processor to be integrated with new OEM car stereos. Newer stereos can detect the presence of connected speakers, and when common amplifiers are connected, the radio will display failure messages with some features, such as fader function, being lost. The ADEP circuit avoids these problems without loading the speaker outputs of the factory stereo during high volumes.

Automatic Signal Detection: Switching from analog to the digital input is done automatically as soon as a digital signal is detected on the Optical input. This feature can be deactivated in the DSP PC-Tool software and can be switched manually with an optional remote control.

Start-Stop Capability: The switched power supply of the UP 7BMW  assures a constant internal supply voltage even if the battery's voltage drops to 6 volts during engine cranking. If the supply voltage drops below 10.5 volts for more than 5 seconds, the amplifier goes into protect mode (Status LED will light red) to avoid any further battery drain.

Power Save Mode: The Power Save Mode will turn off the internal amplifier stages and the remote outputs when the input signal has dropped off for more than 60 seconds. When a signal is re-applied, the amplifier and remote outputs will reactivate within a second. This feature was developed since many newer vehicles use a CAN or BUS system which may "invisibly" keep the factory radio on for up to 45 minutes after the vehicle has been turned off, thus, keeping the sound system active. The turn-off time can be changed or deactivated completely using the DSP PC-Tool software.

MATCH Extension Card slot (MEC): MATCH has included an Extension Card slot inside the processor to accommodate one of their optional Extension Cards such as the HD-Audio USB interface, which adds a high-resolution USB audio input, or the Bluetooth Audio Streaming card (each sold separately). Each of the cards provides an additional input and comes with a replacement side panel for the amp, which provides the necessary cut-outs for the additional ports. To access the Extension Card slot, 2 screws are removed from the end-plate and the bottom plate will slide out giving access to the inside of the unit.

Installation: The UP 7BMW includes a mounting bracket that allows it to be mounted in the same location as the factory amplifier, utilizing the existing mounting hardware. The included wiring adapter plugs into the factory harness, removed from the original amp, and has 2 Molex plugs (System Connector 1 and 2) that plug into the UP 7BMW providing power, ground, and all the speaker input and output wires. If the amp is going to be installed in a non-compatible BMW, the system includes a separate power, ground, and remote terminal-block that can accommodate 8 gauge wire for hardwiring.
