Page 5: Safety Instructions
General Safety Instructions WARNING For your protection, please read the following: Water, Liquids, Moisture: This appliance should not be used near water or other sources of liquids. Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings. - Page 6 Mains Fuse: The mains fuse of this appliance is soldered in place and accessible from the inside only!! A blown fuse may indicate an internal problem and should be replaced during qualified servicing or repair work !! Switchable Power Supply: Connect this unit to the power source indicated on the equipment rear panel only to ensure safe operation !! This unit is provided with an internally settable mains supply for 115 / 230 V AC.

Page 7: The Earth / Grounding Concept
The Earth / Grounding Concept General GROUND-LIFT Jumper (accessible from the inside. Mind the SECURITY INSTRUCTIONS !! ): Ex-works this jumper is set to the LIFT position. The internal ground potential is “lifted” by means of this jumper. As a result, the interconnection for DC voltages and lower frequencies (<... - Page 8 Unfortunately there is no general recommendation how to solve hum and jitter problems - or even minimize them. 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 The VIOLECTRIC DAC V800 is a top-range D/A converter, distinguished by its very particular analog output stages. By means of their specially designed, variable low-noise and low-distortion circuitry, the DAC V800 fulfils even highest demands. Features: - four switchable digital inputs:... -
Page 11: Operation
THE CASE The DAC V800's case as well as the front/rear panels are made of solid aluminium. This choice of material ensures high mechanical stability and resistance. EARTH AND GROUND The DAC V800's case is grounded. Internal reference ground is bridged to protective earth by means of a jumper. -
Page 12: The Digital Inputs
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. You won't find terms like AES, S/P-DIF, professional or consumer here, since it doesn't matter at all which signal type is applied to a dedicated input. - Page 13 THE DIGITAL OUTPUT The digital output is located on the rear panel. It is fitted with a Cinch socket according to IEC 958, unbalanced at 75 ohms output impedance. The level at this output however complies with AES-3-id (1 Vss). The data word on this output is the same as on the selected input by default.
- Page 14 THE ANALOG OUTPUTS The analog outputs are situated on the rear panel, fitted with electroni- cally balanced XLR terminals, as well as cinch sockets. Both outputs may be used simultaneously !! Polarity of the XLR terminals complies with AES 14-1992: 1 = ground, 2 = (+) in phase, 3 = (-) out of phase.
- Page 15 THE MUTE BUTTON Output signal is fully cut by means of the “MUTE“ button. When engaged, the red “MUTE ON / ERROR“ LED will light up. RESAMPLING Resampling is a mighty feature for the transformation/restoration of jittered signals into high-quality signals. As well, the signal quality of 44.1 or 48 kHz sources can be improved by converting them to a higher rate.
- Page 16 - OFF lights up when the resampling function is deactivated. The digital input word is forwarded to the D/A converter without alteration. - x1 The yellow “x1“ LED indicates that the resampling function is activated. The digital input word will be recombined and forwarded to the D/A converter at original sample rate.
- Page 17 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 V800 can be adapted by means of internal DIP switches. While factory-preset to +15dBu, the maximum output level can as well be set to +24 / +18 / +15 / +12 / +6 dBu (with level knob fully clockwise).

Page 18: Things To Know
DIP switches described above. HOW IT ALL WORKS... The DAC V800 offers high-class technology by means of well though- out handling, a variety of inputs, the resampling module, a top-notch converter and, above all, its outstanding and flexible analog output circuitry. - Page 19 In case of the DAC V800, 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 HPA V181. You are in need of two screw drivers TORX style size T8 and T10. You should by all means PULL THE MAINS PLUG !!! Only thereafter the settings can be altered without any hazard. - Page 21 JUMPER SETTING DAC V800...
