Usb Input - Match PP 62DSP User Manual

Initial start-up and functions
1 Subwoofer Output
This output provides for the connection of a passive
Plug & Play subwoofer like the MATCH PP 7E-D
or PP 7S-D. The car-specific setups on our website
always mention the recommended subwoofer type.
When using a subwoofer, we strongly recommend
to connect the PP 62DSP directly to a 12 Volt
source. Refer to connection instructions in section
3b, page 21.
2 Input Sensitivity
This potentiometer allows to increase the input sen-
sitivity of the highlevel inputs up to max. 6 dB. This
function 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 amplifier gain. The con-
trol range of the highlevel input goes from 11 Volts
(max. CCW position) to 5 Volts (max. CW position).
Please note: The input sensitivity ex works is set to
11 Volts (max. CCW position).
3 Clipping LED
This LED lights up red if one of the four highlevel
inputs is overdriven. The LED has no function when
an input signal is applied to the MEC module or if
a car-specific sound setup is used. As soon as the
LED lights up, the input sensitivity should be re-
duced by turning the Input Sensitivity knob count-
er-clockwise until the LED goes out.
4 System Connector
Please use this terminal only in combination with
the cable harness that is included in the delivery of
the amplifier or from the MATCH accessories pro-
gram. Never ever use any other harnesses to con-
nect the MATCH PP 62DSP to your car radio.
Caution: The use of other harnesses than the one
that is supplied with the amplifier may cause severe
harm to the amplifier, your car radio/head unit and
your loudspeakers. In any case the warranty will be
void!

5 USB Input

Connect your personal computer to the PP 62DSP
using the provided USB cable. The required
DSP PC-Tool software to configure this amplifier
can be downloaded from the Audiotec Fischer web-
site www.audiotec-fischer.com.
Please note: It is not possible to connect any USB
storage devices.
6 Control pushbutton
The Control Pushbutton allows the user to toggle
between the two memory areas. Setups with the
extension "af1" or "ac1" will be automatically written
to the first storage position whereas setups with the
extension "af2" or "ac2" will be written to the second
storage position. To switch between the setups, the
button has to be pressed and held for approx. 1 sec-
ond. Switching is indicated by a singular red flash of
the Status LED. Pressing the button for 5 seconds
completely erases the internal memory. This is in-
dicated by a constant flashing of the Status LED.
Attention: After erasing the setups from memory
the PP 62DSP will not reproduce any audio output
until a new setup is loaded.
7 Status LED
The Status LED indicates the operation mode of the
amplifier. Green means that setup 1 (af1) is loaded,
orange means that setup 2 (af2) is loaded.
If it lights up red constantly, the undervoltage pro-
tection is active. A flashing red light indicates that
no setup is loaded. In that case please load a new
setup via the DSP PC-Tool software or the internal
MicroSD card reader.
8 MicroSD card reader
The MicroSD card reader allows the user to easily
copy car-specific setups to the amplifier. First you
have to download a sound setup (e.g. from our web-
site www.audiotec-fischer.com) and copy it to a
MicroSD card. After having inserted the MicroSD
card into the card slot of the PP 62DSP, the file
will be automatically copied to the internal memo-
ry of the amplifier. While the copy is in progress,
the Status LED flashes red. It changes to green
or orange once the process is finished. Now the
MicroSD card can be safely removed.
Attention: Never remove the MicroSD card while
the copy process is in progress!
The PP 62DSP can manage two different set-
up files. They are marked with the file extensions
".af1" / "ac1" (stored in memory 1 of the amplifier) or
".af2" / "ac2" (stored in memory 2 of the amplifier).
Please note: Do not store more than one "af1"
or "ac1" and one "af2" or "ac2" setup file on the
MicroSD card at a time.
