LIST OF FUNCTIONS
Through factory settings a lot of functions are disabled to operate the 077 as a simple preamp. With the menus you are comfortably able to activate the numerous options the 077 offers. In daily use these functions are hidden. If wanted, factory settings can be reestablished.
The most important facts of the factory settings are:
•The output MAIN OUT is the primary output of the preamp to connect to a power amp or active loudspeakers. This output has an adjustable volume (VARIABLE).
•The output RECORD OUT is preset as a recording output to be connected to the input of a recording unit e.g. of an analogue tape deck. This output in factory settings will deliver the maximum volume to the output of the selected input (FIX).
CAUTION: Never connect a power amp or active loudspeakers to this output in FIX mode. Serious damage to your ears and equipments may occur.
•The Input 6 / SURROUND is supposed to be connected to the front-speakers output of a volume adjustable surround decoder. The incoming signals on this input will be put through to the output MAIN OUT with maximum volume bypassing the volume control of the 077.
CAUTION: With these settings never connect a unit to this input without a volume-control. Serious damage to your ears and equipments may occur.

Packaging |
We recommend to keep the original packing in case the unit needs to be shipped in the |
|
future. |
Setting up |
Too low or too high temperatures may cause damage inside of the preamp. Therefore |
|
we recommend you leave the unit to adapt to room temperature, before using it for |
|
the first time. |
|
Carefully remove the unit from its packaging and set it up in an appropriate location. To |
|
protect the preamp 077 from overheating make sure that the location offers sufficient air |
|
circulation around the unit. Also, avoid excessive exposure to sun, dust and humidity. |
|
Please make sure that your desired location for the preamp is stable enough to carry its |
|
weight. |
|
Ventilation ducts and openings in the housing serve to keep the unit cool. They must not be |
|
covered up with magazines, tablecloth, curtains etc. |
|
If the preamp has to be operated in an extremely warm environment it may be |
|
necessary to supply additional ventilation. Avoid operating the unit in an excessively |
|
humid environment like bathrooms etc. |
Set up variations |
The feet of the preamp and of the power supply unit are constructed as spikes. They can |
|
either be placed directly on the aluminum of the base plate or on the supplied carbon fiber |
|
damping discs. Using the Kevlar fiber damping discs additionally decouples the entire |
|
housing acoustically from the ground surface. |

CONNECTIONS
THE “SIMPLE“ PREAMP - FACTORY SETTINGS
All connection terminals are located on the rear panel. While connecting the preamp, all components of the music system must be turned off.
Through factory settings a lot of functions are disabled to operate the 077 as a simple preamp. With the menus you are comfortably able to activate the numerous options the 077 offers. In daily use these functions are hidden. If wanted, factory settings can be reestablished.
Inputs |
To connect source components like CD-Player, FM-Tuner, Tape deck etc. the standard |
|
version of the preamp provides five balanced inputs (XLR) named INPUT 1 to INPUT 5 |
|
(24) and one unbalanced module input (RCA) named INPUT LINE (25). For the best |
|
sound we recommend using the balanced inputs whenever possible. |
|
Instead of the LINE module the preamp may be equipped alternatively with Phono MC |
|
module, Phono MM module or with a D/A converter module. |
|
The pinning of the balanced inputs is: PIN1=GND, PIN2=NEG, PIN3=POS. |
SURROUND input
!
Adapter Plugs
The two front channels (right front / left front) of a surround sound processor or decoder must be connected to the INPUT 6/SURR (23). In this configuration the signal is sent directly to the MAIN outputs (not to the RECORD outputs), bypassing volume control.
Therefore connect only components with their own volume control to the SURROUND input!
This input allows the easy integration of surround sound components into an existing twochannel hifi system.
The SURROUND input cannot be selected over the RECORD level.
The pinning of the SURROUND input is: PIN1=GND, PIN2=NEG, PIN3=POS.
CAUTION: Never connect a unit to this input without its own volume control. Serious |
! |
|
|
damage to your ears and equipments may occur. |
|
If your stereo components should only offer unbalanced outputs, you are able to use our balanced inputs with the adapter plugs as unbalanced inputs. In these adapter plugs the Pins 2 (negative input) and Pin 1 (ground pin) are connected (see graphic below). 4 XLRRCA adapters plugs are delivered with the units, allowing you to use 2 inputs as unbalanced inputs. If you need further plugs you may get them at your authorized dealer.
NOTICE: Please do only use BURMESTER XLR-RCA adapter.

Module input |
The module input (25) may be equipped alternatively with 4 different modules: |
•LINE module
The standard version of the preamp is equipped with a LINE module. In this case the module input is an unbalanced high-level input.
NOTICE: Subsequent installation of other modules must only be done by your authorized dealer or by Burmester Audiosysteme GmbH.
•PHONO MC module
With a PHONO MC module the module input is a balanced PHONO MC input to connect a record player with moving coil pickup (no high output MC).
If your pickup has an unbalanced output, the balanced PHONO MC input can be converted to unbalanced mode by using XLR-RCA adapter plugs.
The input resistance and the amplification of the PHONO MC module can be attuned to your pickup with the MC SETUP. For detailed instruction please refer to the chapter THE SETUP MENUS / MC SETUP.
The PHONO SETUP offers an automatic channel calibration, which verifies the channel equality of your pickup and adjusts it, if necessary. The PHONO SETUP also offers the chance to switch on a subsonic filter to eliminate low frequency noise.
The pinning of the balanced PHONO MC input is: PIN1=GND, PIN2=NEG, PIN3=POS.
On request the PHONO MC modules and the adapter plugs are available at your local dealer.
NOTICE: Subsequent installation of other modules must only be done by your authorized dealer or by Burmester Audiosysteme GmbH.
•PHONO MM module
With a PHONO MM module the module input is a balanced PHONO MM input to connect a record player with moving magnet pickup or high output moving coil pickup.
If your record player has an unbalanced output, the balanced PHONO MM input can be converted to unbalanced mode by using XLR-RCA adapter plugs.
The input capacitance and the amplification of the PHONO MM module can be attuned to your pickup with the MM SETUP. For detailed instruction please refer to the chapter THE SETUP MENUS / MM SETUP.
The PHONO SETUP offers an automatic channel calibration, which verifies the channel equality of your pickup and adjusts it, if necessary. The PHONO SETUP also offers the chance to switch on a subsonic filter to eliminate low frequency noise.
The pinning of the balanced PHONO MM input is: PIN1=GND, PIN2=NEG, PIN3=POS.
On request the PHONO MM modules and the adapter plugs are available at your local dealer.
NOTICE: Subsequent installation of other modules must only be done by your authorized dealer or by Burmester Audiosysteme GmbH.

• D/A converter module
With the D/A converter module inserted two inputs for digital audio signals will be available: an unbalanced chinch input (RCA), which can receive pulse coded signals (PCM) in the usual S/P-DIF format with a maximum sampling rate of 192kHz, and a USB input, which supports USB class 1 audio and USB class 2 audio, depending on the operating system of your computer. Since the USB input is a so-called slave connection, no USB sticks or USB hard disks may be connected.
The RCA and USB inputs are selected by either pressing the MODULE FUNCTION (12) key on the front panel of the device or by pressing and holding the AUDIO button on the remote control for about 2 seconds. The active input will be indicated on the display.
The sampling rate is toggled between 96kHz and 192kHz by pushing up the MODULE FUNCTION (12) key on the front panel of the device or by shortly pressing the AUDIO button on the remote control. With a sampling rate of 192kHz the AUDIO LED (3) will be lit.
The level of both the RCA and USB inputs can be preset individually, see THE SETUP MENUS / GLOBAL SETUP.
• USB Connection
To establish the connection we will describe the variants for Microsoft and Apple operating systems.
Connecting the 077 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 077. 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 077 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 077 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 077 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 077. So if the PC volume level is set to zero, the 077 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 (26). Loosen the GND screw, clamp the GND wire of your turntable between the two washers and tighten the GND
|
screw. The GND-screw is only assembled when a Phono module is equipped. |
|
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 OUTPUT MAIN |
|
(21) as a regular balanced preamp output. |
|
This output provides the volume-controlled signal of the selected input of the MAIN level. e |
|
pinning of the OUTPUT MAIN is: PIN1=GND, PIN2=NEG, PIN3=POS. |
10
RECORD output The output terminal OUTPUT REC (22) 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 of the RECORD level at maximum volume level. Signals from the inputs TAPE and SURROUND cannot be taken from the RECORD output.
Through factory settings, volume controls have no bearing on the signal at the RECORD output.
If no recording is desired, the RECORD output may be used as a second volume controlled preamp output. (see chapter RECORD SETUP)
The pinning of the OUTPUT REC is: PIN1=GND, PIN2=NEG, PIN3=POS.
!CAUTION: Never connect a power amp or active loudspeakers to this output with ! these settings. Serious damage to your ears and equipments may occur.
Headphone jacks The headphone jacks PHONES 1 (19) and PHONES 2 (20) require headphones with a 6,3mm stereo plug and an impedance of 16Ω or more. Each of the phones output can playback the MAIN and the RECORD level. The PHONES MENU gives you the option to choose your favorite settings. 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 outputs.
NOTICE: The signal at the MAIN or RECORD output will be interrupted while inserting a headphone plug into the headphone jacks.
REMOTE |
Connecting DC OUT (27) to the corresponding DC IN-jack of another BURMESTER-unit |
|
offers the function to switch on or off this other unit simultaneous by the 077. In this case, |
|
the 077 has the master function. |
|
Connecting DC IN (28) to the corresponding DC OUT-jack of another BURMESTER-unit |
|
offers the function to switch on or off the 077 simultaneous by the other unit. In this case, |
|
077 has the slave function. |
BURLINK |
To the BURmester-LINK interface plugs (17), (18) a computer system e.g. PC, |
|
CRESTRON , AMX can be connected to the preamp 077. The computer system allows a |
|
comfortable control of your High End system using for example an individual programmable |
|
touch panel. With the LEDs beside the plugs named T and R (Transmit and Receive) you |
|
are able to monitor whether data exchange is working. |
|
You will find the commands to control the 077 in the chapter BURLINK. |
