Page 10: General
GENERAL INFORMATION VIOLECTRIC HPA V202 contains a high-grade stereo Headphone Amplifier designed to drive low-, medium- and high-Z loads (16...600 ohms) as usually represented by high-quality headphones. Due to its specific, highly variable, low-noise and low distortion circuit design especially optimised for dynamic and orthodynamic headphones, HPA V202 fulfils even highest demands. -
Page 11: Operation: Case, Power Supply, Power Switch
THE CASE of VIOLECTRIC HPA V202 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. -

The unit is put into operation by means of the power switch. The power-on procedure takes about 5 seconds. Any breakdown will cause the headphone outputs to be switched off to protect the headphones. User´s Manual HPA V202, October 2022, F. Reim... -

Page 15: About Pre-Gain
Too loud ? Too soft ? The PRE-GAIN method The VIOLECTRIC HPA V202 is specially designed to drive headphones. To do so it is placed between up to two analogue sources and the headphones. - Page 16 PRE-GAIN WE CALL THE SOLUTION TO THIS PROBLEM A single amp of HPA V202 has a gain of +8 dB (factor 2,5). By this measure the amps will produce an extremely low self- generated noise which can hardly been heard even with highest sensitive in-ear-monitors (IEM).
- Page 17 HOW TO OPTIMIZE THE PRE-GAIN SETTING: Connect your source to VIOLECTRIC HPA V202 and plug in your headphones. Listen !! Your amp is adjusted best by the individual PRE-GAIN setting when the volume control for “normal” listening is positioned around 12 o´clock.

Page 18: Protective Measures
PRE-GAIN - which should be sufficient for most applications. PROTECTIVE MEASURES: To ensure error-free operation and not to harm your valuable headphones in a comprehensive way your VIOLECTRIC HPA V202 is equipped with some protective circuits: During powering on there is a five second delay to protect your headphones from possibly unwholesome noises. -

Why makes it sense to make such huge efforts? A headphone amplifier is a device designed to condition audio signals with regards to the very specific requirements of headphones. This doesn't sound too spectacular at the first glance User´s Manual HPA V202, October 2022, F. Reim... - Page 20 Why does PRE-GAIN make sense? Two extreme examples (with the HPA V202 with +8 dB gain = factor 2,5, volume control set to full): User´s Manual HPA V202, October 2022, F. Reim...
- Page 21 At the low end of the scale, this limit is represented by DC, as there is no frequency lower than zero. In upward direction, the limit can be set to practically any frequency, but the higher, the more susceptible the device becomes concerning electro-magnetic User´s Manual HPA V202, October 2022, F. Reim...
- Page 22 Since there is no known technical specification, we define the load (voice coil impedance) as 50 Ohms. With HPA V202 having an output impedance of < 0.25 Ohms this results in a damping factor of 200.
- Page 23 (95 % of all headphone amps in the market are operated with these or even lower supply voltages). Due to the high supply voltage and the balanced operation mode of HPA V202 you will benefit from far over two times more output voltage swing capability compared to single ended amps with “standard”...
