Violectric HPA V324
Premium analog headphone amplifier for uncompromising sound purity
The Violectric HPA V324 is a powerful, fully balanced headphone amplifier with preamp functionality. It combines the best technologies and decades of experience from Lake People, Violectric and Niimbus.
Key Features
- Four amplifier stages for a genuine TRUE-BALANCED design
- Two analogue inputs: XLR (balanced) and RCA (unbalanced)
- Motorized, remote-controllable volume potentiometer with PRE-GAIN adjustment
- Precision VU meters for real-time signal monitoring
- Preamp mode with switchable line outputs (Head / Off / Line, Pre/Post)
Connections
- Analogue stereo inputs: 1× XLR (balanced), 1× RCA (unbalanced)
- Headphone outputs: 4-pin XLR (balanced), 4.4 mm Pentaconn (balanced), 6.3 mm (1/4") TRS (unbalanced)
- Analogue stereo outputs: 1× XLR (balanced), 1× RCA (unbalanced)
Versatile Performance
Whether used as a headphone amplifier or as a high-end preamplifier, the HPA V324 easily drives demanding headphones, power amps, or active speakers. Independently switchable outputs make it a flexible control hub for studio and high-end setups.
Balanced Listening
The balanced outputs (4-pin XLR / Pentaconn) deliver superior channel separation and precise reproduction. Four separate amplifier stages provide clean, highly accurate amplification for reference-grade sound.
PRE-GAIN Matching
Six gain steps from -18 dB to +12 dB can be selected directly from the front panel—ensuring optimal volume control, perfect source matching, and an exceptionally low noise floor.
Protection Circuits
- Delayed power-on & instant power-off
- DC monitoring with automatic disconnect in case of overvoltage
- Overload monitoring to protect connected headphones
Technology Highlights
- Extremely low self-noise thanks to low internal gain
- ±50 V internal supply for high output voltage—ideal for high-impedance headphones
- Very high output power for low-impedance and planar magnetic models
- Ultra-low output impedance for high damping factor and linear frequency response
With timeless elegance and robust build quality, Violectric brings professional studio engineering into the high-end world—for music lovers who demand uncompromising quality.
Features
- TRUE-BALANCED technology: Four output stages for genuine balanced playback—maximum signal integrity for high-resolution audio.
