MATCH UP 7DSP

The UP 7DSP is the most powerful MATCH DSP amplifier, built around the ADEP.3 circuit. Seven amplifier channels plus an additional preamp output, combined with the integrated 8-channel DSP, allow it to drive complex individual speaker configurations. Two of the output channels deliver 160 W RMS at 2 ohms, making them capable of powering large subwoofers. For additional subwoofer amplification, the Match UP 1FX mono subwoofer amplifier can be connected via the mono RCA output.

With the optional MEC ANALOG IN extension card you can:

• Upgrade OEM premium sound systems that require 2 additional high-level inputs with up to 30 V input sensitivity
• Provide the amplifier with a low-level signal
• Connect an additional analogue signal source such as a TV or smartphone

The 2 additional high-level inputs include the ADEP.3 circuit, Auto Remote function and adjustable input sensitivity from 1.5 to 30 V. The 3.5 mm low-level stereo input offers adjustable sensitivity from 0.5 to 8 V. Configuration is handled via the DSP PC-Tool software V4.

• 7-channel Class HD upgrade amplifier with integrated 8-channel 64-bit DSP for universal applications
• MATCH Extension Card slot (MEC) for additional input/output modules including Bluetooth Audio Streaming and High Resolution Audio Streaming via USB
• Smart high-level input with ADEP.3 circuit (Advanced Diagnostics Error Protection) and Auto Turn-On function
• DSP features include Augmented Bass Processing, StageXpander, and RealCenter for focused sound staging for both driver and co-driver
• Easy configuration via the intuitive DSP PC-Tool software
• Start-Stop capable down to 6 V supply voltage
• Optical input in SPDIF format with sampling rate between 12 and 96 kHz
• Mono RCA output for connection of an external amplifier
• Compact dimensions and low heat dissipation

Special features

Class HD technology

The UP 7DSP combines Class H technology with Class D amplifier principles. By varying the internal supply voltage in line with the amplitude of the input signal, idle losses are significantly reduced and efficiency is kept close to maximum at all times.

Smart high-level input ADEP.3

Modern factory radios use sophisticated speaker diagnostics that can trigger failure messages or loss of features such as the fader function when an aftermarket amplifier is connected. The ADEP.3 circuit (Advanced Diagnostics Error Protection, 3rd Generation) prevents these issues without placing unnecessary load on the OE radio's speaker outputs at high volumes.

Start-Stop capability

The switched power supply maintains a constant internal supply voltage even if the battery drops to 6 V during engine crank. If supply voltage falls below 10.5 V for more than five seconds, the amplifier enters Protect mode (Status LED lights red) to prevent further battery discharge.

Automatic Digital Signal Detection

The amplifier switches automatically from analogue to digital input as soon as a signal is detected on the optical input. This can be deactivated in DSP PC-Tool software, or an optional remote control can be used to switch manually between inputs.

Power Save Mode

Power Save Mode is active by default. If no input signal is present for more than 60 seconds, it reduces power consumption on the UP 7DSP and any connected amplifiers by switching off the remote output. The remote output reactivates within one second when a music signal is applied. The 60-second turn-off time can be adjusted or the mode disabled entirely via DSP PC-Tool software.
