Match UP 8DSP + BMW 1.7HiFi (UP 8BMW ver.2) power amplifier (8-channel) with DSP for BMW.

Match UP 8DSP + BMW 1.7HiFi // UP 8DSP (GD class) power amplifier (8-channel).

Class GD technology
Audiotec Fischer´s proprietary Class GD concept takes the efficiency of conventional Class D amps to the next level. 
By varying the internal supply voltage in several steps depending on the amplifier’s input signals, idle losses are significantly reduced and overall efficiency is close to maximum at any time. 
So heat dissipation is almost negligible, thus allowing smallest heat sinks and most compact form factors.
ACO – Advanced 32 Bit CoProcessor
The UP 8DSP incorporates an extraordinary powerful 32 Bit CoProcessor of the latest generation. 
This not only takes over all control tasks ultra-fast, but also the lightning-fast switching between up to ten possible sound setups.
But ACO offers much more – besides a channel-separated Input EQ including Input Signal Analyzer (ISA) for easy analysis and compensation of input signals of OE radios and fantastic sound effects like 
Augmented Bass Processing or RealCenter, there is now the revolutionary TuneEQ function for automated adjustment of the output equalizers.
A further significant advantage is the integrated, native boot loader of the CoProcessor. It allows software upgrades of all components of the DSP in order to adjust the microcontroller-controlled 
ADEP.3 circuit for example at future modifications / changes in the diagnostic system of factory radios or if the device will be extended with additional interfaces.
Smart highlevel input ADEP.3
Modern, factory-installed car radios incorporate sophisticated possibilities of diagnosing the connected speakers. 
In particular the latest generation of car radios are equipped with additional monitoring functions so that failure messages and loss of specific features (e.g. fader function) quite often appear if a common amplifier will be hooked up – but not with the UP 8DSP.
The new ADEP.3 circuit (Advanced Diagnostics Error Protection, 3rd Generation) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.
Start-Stop capability
The switched power supply of the MATCH UP 8DSP assures a constant internal supply voltage even if the battery’s voltage drops to 6 Volts during engine crank. 
If the supply voltage drops below 10.5 Volts for more than five seconds the amplifier goes to “Protect mode” (Status LED lights up red) in order to avoid any further discharge of the car’s battery.
Automatic Digital Signal Detection
The UP 8DSP allows signal-controlled switching between the analog inputs and the digital input. As soon as an input signal is detected on the Optical Input, the amplifier automatically switches to this input. 
This feature can be deactivated in the DSP PC-Tool software. Alternatively you can use an optional remote control for manual switching between analog and digital inputs.
Power Save Mode
The Power Save Mode is incorporated in the basic setup. 
It allows to significantly reduce the power consumption of the UP 8DSP and potentially connected amplifiers once there’s no input signal present for more than 60 seconds. 
Please note that in many up-to-date cars with “CAN” or any other internal bus structures it may happen that the radio remains “invisibly” turned on for up to 45 min. even after locking and leaving the car! 
Once the “Power Save Mode“ is active the remote output and therefore the connected amplifiers will be turned off. 
The MATCH UP 8DSP will reactivate the remote output within a second if a music signal is applied. It is possible to either modify the turn-off time of 60 sec. or completely deactivate the “Power Save Mode” via the DSP PC-Tool software.
