Page 3: About Lake People
Among others, the first German-made 20-bit A/D and D/A converters were developed by Lake People in the early nineties of the past century. Who manufactures Lake People equipment ? The devices are exclusively manufactured in Germany by Lake People electronic GmbH or contractors in the company's vicinity. - Page 4 … and if it doesn't work like it should ? Lake People devices are covered by a 24-month warranty. In case of any malfunction during this period, they can be shipped to the manufacturer directly. Of course, the client will benefit from Lake People's full technical support even when warranty has expired.

The best way to succeed is to check different options !! In case of balanced cables, it should always been verified if the shield of the cable is connected to the shell of the XLR connector.

GENERAL INFORMATION LAKE PEOPLE DAC RS 06 is a top-range D/A converter, distinguished by its resampling unit, its 32-bit double mono converters and very particular analog output stages. By means of their specially designed, variable low-noise and low-distortion circuitry, the DAC RS 06 fulfils even highest demands. - Page 11 This choice of material ensures high mechanical stability and resistance. EARTH AND GROUND The case of DAC RS 06 is grounded. Internal reference ground is bridged to protective earth by means of a jumper. The jumper is set to the 'LIFT' position (see also: page 7 "Earth/Ground concept", page 23 "Technical Appendix").

Page 12: Operation
THE POWER SWITCH The unit is activated by means of the power switch. Power-on status is indicated by the green LED below. THE DIGITAL INPUTS Four digital inputs are found on the unit's rear panel. They are denoted according to their electrical properties: balanced, coaxial (unbalanced), optical and USB. - Page 13 dependend on your specific computer and/or software. The 24/96 USB input is USB 1.1 based and normally runs without a specific software. For the 24/192 USB circuitry a special driver is needed which can be downloaded on our web site www.violectric.com www.violectric-usa.com In order to avoid any interference caused from the host, the USB...

Page 14: About Resampling
Polarity of the XLR terminals complies with AES 14-1992: 1 = ground, 2 = (+) in phase, 3 = (-) out of phase. Source impedance of all analog outputs is significantly lower than 1 (one) Ohm ! NOTE: When connecting unbalanced lines to the balanced outputs, pin 3 must not be bridged but left unused (open). - Page 15 The quality of this recombination is directly dependent from the SRC´s clock source. Therefore inside DAC RS 06 a special low jitter oscillator with typical < 1 pS (Picosecond !) phase jitter is used. The oscillator is powered by a low noise source made of discrete components.

Page 16: The Menu
THE MENU consists of two points. To enter the MENU push and hold the right “RESAMPLING” button for two seconds. The yellow “ON“ LED flashes constantly. The green LED under “BAL” flashes once to show that Menu 1 is entered. Afterwards it is either on or off. - Page 17 Depressing shortly the right button again calls the 2nd Menu item. The yellow “ON“ LED keeps flashing constantly. The green LED under “COAX” flashes once to show that Menu 2 is entered. Afterwards it is either on or off. 2nd Menu item: the phase correlation of the analog outputs The status may be altered by pushing the left button.

Page 18: The Analog Output Level
Notabene, +15 dBu represent a voltage of 4.5 Veff which may exceed the capabilities of many audio devices designed for a voltage swing of 1...2 volts. Therefore, the maximum output level of the DAC RS 06 can be adapted by means of software. While factory-preset to +15dBu, the maximum balanced output level can as well be set to +21 / +15 / +9 / +3 dBu. - Page 19 THE SETTING OF THE ANALOG OUTPUT LEVEL To enter the setting push and hold the left “INPUT SELECT” button for two seconds. The blue “LOCK” LED flashes constantly. One or more green LEDs will be lit constantly. 1 LED = output level +3 (-3) dBu for 0 dBFs 2 LEDs = output level +9 (+3) dBu for 0 dBFs 3 LEDs = output level +15 dBu (+9) for 0 dBFs (ex works) 4 LEDs = output level +21 (+15) dBu für 0 dBFs...

Page 20: How It Al Works
Each converter is based on a delta-sigma architecture and provides a dynamic range of 124 dB. According to the double-mono architecture two 32 bit D/A converters per channel are used inside DAC RS 06 to achieve higher linearity and lower noise. An incoming 16, 20 or 24 bit signal is expanded in a 32 bit signal inside the converters. - Page 21 In case of DAC RS 06, the converter is followed by an amplifier specially designed for this purpose, with a topology similar to an instrumentation amplifier.

DISMANTLING / JUMPER SETTINGs Hint: Here we are talking about internal adjustments inside your DAC RS 06. You are in need of a screw drivers TORX style size T10 or a 3mm hex allen key. You should by all means PULL THE MAINS PLUG !!! Only thereafter the settings can be altered without any hazard. -
