Page 10: General
GENERAL INFORMATION VIOLECTRIC DHA V226 contains an excellent D/A Converter, a first- class Preamplifier and a high-grade stereo balanced Headphone Amplifier designed to drive low-, medium- and high-Z loads (16...600 ohms) as usually represented by high-quality headphones. Because of its four built-in amplifiers and both front mounted balanced headphone sockets (4-pin XLR and 4.4 mm Pentaconn) it is... - Page 11 THE CASE of VIOLECTRIC DHA V226 is made of 4 mm Aluminum and a thick 5 mm aluminum front panel. This choice of material ensures high mechanical stability and resistance whilst maintaining a high optical and haptic quality.
- Page 12 GROUND AND PROTECTIVE EARTH The case of VIOLECTRIC DHA V226 is connected to protective earth. POWER SUPPLY Mains power is provided via a three-pin IEC/CEE socket and mating "cold-appliance" mains cord with Schuko-type plug for units purchased in middle Europe.

Page 16: D/A Converters
THE DIGITAL to ANALOGUE CONVERTER (D/A Converter) inside DHA V226 is the Cirrus Logic CS43131. It is a high performance 32-bit solution designed for Audiophile and Studio equipment applications. PCM data up to 384 kHz and DSD 64 – 256 is accepted. - Page 17 PRE-GAIN WE CALL THE SOLUTION TO THIS PROBLEM A single amp of DHA V226 has only little gain (gain = +2,5 dB = factor 1,25). In case a balanced headphone is connected two amps are active with a combined gain of +8 dB (factor 2,5).
- Page 18 PRE-GAIN settings +6 / +12 / +18 dB to achieve more gain (factor 2 / 4 / 8). Other than the above settings are not useful but harmless. User´s Manual DHA V226, November 2021, F. Reim...

Page 22: Error Reporting
ERROR REPORTING: To ensure error-free operation and not to harm your valuable headphones in a comprehensive way your VIOLECTRIC DHA V226 is equipped with some protective circuits: During powering on there is a five second delay to protect your headphones from possibly unwholesome noises. - Page 23 Why does PRE-GAIN make sense? Two extreme examples (with the DHA V226 with +2 dB gain (factor 1,25), volume control set to full): 1st example: The (pre-) amplifier provides 8 V output voltage, whereas the headphone requires only 2 V for 100 dB sound pressure level.
- Page 24 Conductive-plastic resistive tracks, high-quality multi-tap wipers and separated chambers for the individual sections are highly desirable for sophisticated applications, and high quality is inevitable to ensure trouble-free operation for years. Since the market for really good pots is User´s Manual DHA V226, November 2021, F. Reim...
