OPERATION MANUAL 088 PREAMP
PLEASE NOTE: Don’t use any other tools but your hand to tighten the
GND screw! This way you avoid overwinding the screw.
MAIN output
To connect power amps or active loudspeakers the preamp provides the
MAIN output (19) as a regular balanced preamp output.
This output provides the volume-controlled signal of the selected input.
The pinning of the OUTPUT MAIN is: PIN1=GND, PIN2=NEG, PIN3=POS.
TAPE output
The output terminal TAPE output (20) must be connected to the recording input of
an analog recording device (mostly named TAPE IN or REC).
This output provides the signal of the selected input at maximum volume level.
Signals from the inputs TAPE and SURROUND cannot be taken from the
TAPE output. The volume control has no bearing on the signal at the TAPE output.
Die Lautstärkeregelung hat auf das Signal am TAPE-Ausgang keinen Einfluss.
The pinning of the TAPE output is: PIN1=GND, PIN2=NEG, PIN3=POS.
NOTICE: Never connect a power amp or active loudspeakers to this
output. Serious damage to your ears and equipments may occur.
Headphone jack
The headphone jack PHONES (18) requires headphones with a 6.3mm (1/4")
stereo plug and an impedance of 16Ω or more. For security measures the volume
level is being reduced to 01 respectively -79dB while inserting or pulling off the
phones plug. With the volume selector (6) on the front panel or with the buttons
VOLUME + and. VOLUME – on your remote control you select the volume level of
the phones output.
NOTICE: The signal at the MAIN OUTPUT will be interrupted while
inserting a headphone plug into the headphone jacks.
USB Connection
To establish the connection we will describe the variants for Microsoft and Apple
operating systems.
Connecting the 088 to a Windows™ operating system for the first time will
automatically prompt the installation of the USB class 1 audio driver. In the system
management of your operating system you may then select the Burmester class 1
audio output from the list of audio devices. When playing back music over the PC
now, it will be output via the 088. Regrettably problems may occur on Windows PCs
in connection with class 2 audio. Therefore we recommend selecting USB class 1
audio on PCs with Microsoft operating systems.
The Apple® operating systems automatically recognize both USB class 1 audio and
USB class 2 audio. To select between class 1 and class 2 audio, simply press the
OSD button on the remote control or the MODULE FUNCTION (12) key on the 088
for about 2 seconds. The operating system will automatically recognize the
selected connection and activate it. You may then adjust the sampling rate
between PC and 088 in the audio settings of the operating system to as high as
192kHz / 24 bit.
USB Quality
The quality of the two USB audio classes differs in their sampling rate.
The D/A converter module of the 088 offers two options to establish a
USB connection: either as USB class 1 audio or as USB class 2 audio. USB class 1
audio can transmit signals of up to 96 kHz / 24 bit while class 2 audio can handle
signals of up to 192kHz / 24 bit.
PLEASE NOTE: The volume level may be controlled either from the PC or
from the 088. So if the PC volume level is set to zero, the 088 will receive
no signal.
GROUNDING screw
When using the PHONO input as an unbalanced input for a record player it is
necessary to connect the GND wire of your record player to the GND screw (24).
Loosen the GND screw, clamp the GND wire of your turntable between the two
washers and tighten the GND screw.
