Audiotec Fischer Match UP 7BMW Bedienungsanleitung Seite 18

Initial start-up and functions
9 USB Input
Connect your personal computer to the UP 7BMW
using the provided USB cable. The required
PC software to configure this amplifier can be
downloaded from the Audiotec Fischer website
www.audiotec-fischer.com.
Please note: It is not possible to connect any USB
storage devices.
Control pushbutton
10
The Control pushbutton allows the user to switch
between the two setup memory positions. To switch
between the setups the button has to be pressed
and held for one second. Switching is indicated by a
single red flash of the Status LED. Pressing the but-
ton for five seconds completely erases the internal
memory. This is indicated by a constant red flashing
of the Status LED.
Attention: After erasing the setups from memory
the MATCH UP 7BMW will not reproduce any audio
output.
Status LED
11
The LED indicates the operating mode of the ampli-
fier and which setup has been chosen.
Green: Setup 1 is loaded.
Orange: Setup 2 is loaded.
Red: Undervoltage protection circuit is
active.
Red flashing: Internal setup storage is empty (A
new setup has to be loaded via
the DSP PC-Tool software).
Control Input
12
This multi-functional connector is designed for
MATCH accessory products like a remote control
which allows to adjust several features of the am-
plifier. Depending on the type of remote control, the
functionality at first has to be defined in the "Device
Configuration Menu" of the DSP PC-Tool software
or on the remote control itself.
Optical Input
13
Optical input in SPDIF format for connecting signal
sources with a digital audio output. The sampling
rate of this input must be between 12 and 96 kHz.
The input signal is automatically adapted to the in-
ternal sample rate. In order to activate and control
the volume of this input, we recommend to use an
18
optional remote control.
Note: This amplifier can only handle stereo input
signals and no MP3- or Dolby-coded digital audio
stream!
Note: It is possible to use the Optical Input and the
highlevel inputs of the System Connector 1 at the
same time.
Gain
14
This control allows to increase the input sensitivity
of the highlevel inputs up to max. 12 dB. The func-
tion should only be used if the signal source has a
low output volume. This is not a volume control, it´s
only for adjusting the amplifiers gain. Adjustments
with this control do not affect the optical input!
The control range of the highlevel input goes from
8.3 Volts (max. CCW position) to 2.0 Volts (max.
CW position).
Please note: The input sensitivity ex works is set to
8.3 Volts (may. CCW position). This is definitely the
best setting for most applications.
Remote Out
15
We strongly recommend to use this output for turn-
ing on/off additional amplifiers that are connected
to the Line Out of the MATCH UP 7BMW. This is
essential to avoid any interfering signals. This out-
put is activated automatically as soon as the boot
process of the DSP is completed. Additionally this
output will be turned off during the "Power Save
Mode" or a software update process.
Line Out
16
The Line Out is a mono floating-ground low level
output (max. 3 Vrms) for connecting additional pow-
er amplifiers. A specially designed "Balanced Audio
Transformer" avoids any ground-loops that may
cause undesired alternator noise. Please make
sure that you always turn on / off external ampli-
fiers using the remote output (Remote Out) of the
UP 7BMW. Additionally this output will be turned off
when the "Power Save Mode" of the amplifier is ac-
tive as well as during software updates.
The output can be configured independently of the
other amplifier channels with the DSP PC-Tool soft-
ware.
