The headphone amp HPA RS 02 use the highly regarded and reliable technique of Violectric HPA V100 which is known and honored for its powerful and neutral sound. Of course all other features of our famous headphone amps can also be found here.
The Features:
- Unbalanced inputs with gold-plated RCA connectors
- Unbalanced line-outputs with gold-plated RCA connectors
- PRE-GAIN = switchable input gain in five steps
- Line-outputs internally switchable to three modes:
- Passive feed-through
- Active feedthrough without volume control (pre fader)
- Active feedthrough with volume control (post fader)
- ALPS RK27 High-Grade volume control
- High-Quality op-amps in the signal path
- High-quality MKP capacitors in the signal path
- 0.1 and 1% metal film resistors throughout the unit
- power amps with 4 transistors per channel
- 2 silver-plated Neutrik headphone outputs
- Relay-based delayed headphone output cut-off
- Toroidal transformer
- Large filtering capacitors in the power supply
- Switchable ground lift
- Rugged aluminum case, black anodized
- Aluminum front- and back panel
