Page 14: Protective Measures
PROTECTIVE MEASURES: To ensure error-free operation and not to harm your valuable headphones in a comprehensive way your VIOLECTRIC HPA V101 is equipped with some protective circuits: During powering on there is a five second delay to protect your headphones from possibly unwholesome noises. After the time the headphone outputs are switched to the amp. -
Page 15: About Pre-Gain
A single amp of HPA V101 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). On the other hand, the amps of HPA V101 with very powerful transformers and with their high operating voltage are able to drive low efficiency or high impedance headphone to the full with ease. - Page 16 The "VOLUME" control should be set to minimum. Left and right channel settings should be the same unless you want to settle the amp for different hearing abilities. User´s Manual HPA V101, October 2024, F. Reim...

Two extreme examples (with the VIOLECTRIC HPA V101 with +8 dB gain = factor 2,5, volume control set to full): 1st example: The (pre-) amplifier provides 8 V output voltage, whereas the headphone requires only 4 V for 100 dB sound pressure level.
