Analog Premium Headphone Amplifier for Uncompromising Signal Purity
+++ Inputs switchable on the front panel +++
The HPA V324 excels as both a headphone amplifier and a high-quality preamplifier. With the ability to connect headphones, power amplifiers, or active speakers via individually switchable outputs, it provides a perfect solution for professional and audiophile applications.
Balanced operation with 4-pin XLR or Pentaconn connectors ensures significantly improved channel separation, resulting in more precise and clear sound reproduction. To fully realize the potential of balanced playback, the Violectric HPA V324 employs sophisticated engineering with four separate amplifier stages, delivering exact and distortion-free amplification for each channel. This guarantees exceptional sound quality for the highest audiophile standards.
When listening through speakers, you’re part of the audience. With regular headphones, you take the conductor’s place. With balanced headphones, you’re part of the orchestra.
The PRE-GAIN adjustment allows optimal matching of various sources and headphones. It ensures precise volume control and compensates for variations in input signals. The result is outstanding sound reproduction with minimal noise, virtually no distortion, and perfect channel balance.
The fine-tuned gain range from -18 to +12 dB, adjustable in 6 steps, is located on the front panel of the Violectric HPA V324 for customized adaptation to your audio equipment.
Multiple circuits safeguard the headphones against unclear operating conditions, DC voltage, excessive operating temperature, and overload:
Delayed ON, Instant OFF
Relays and associated electronics connect the headphones to the amplifier with a delay and disconnect them instantly upon shutdown.
DC Monitoring
Outputs are monitored for harmful DC voltage, disconnecting the headphones if a predefined threshold is exceeded.
Overload Monitoring
Power consumption is continuously measured during operation, with headphones disconnected if predefined parameters are exceeded.
