The Violectric DHA V590-2 PRO is a reference-grade all-in-one system combining a balanced headphone amplifier, a high-end DAC, and a line preamplifier. This second-generation (V2) unit features a redesigned motherboard and optimized circuitry, delivering the surgical precision required for mastering and critical listening in professional studio environments.
Relay-Controlled Volume and 32-Bit ESS Conversion
Maintaining perfect channel balance at low volume levels is a major challenge in professional monitoring. The PRO version addresses this via a 256-step resistor ladder network controlled by reed relays, ensuring mathematical accuracy in stereo imaging. Digital-to-analog conversion is handled by dual 32-bit ESS ES9026 PRO chips in a dual-mono configuration, significantly reducing THD and noise while offering a pristine dynamic range of 124 dB.
50V Rails and Versatile Pre-Gain Staging
Driving power-hungry planar headphones while maintaining a pitch-black background for sensitive IEMs requires massive dynamic flexibility. The DHA V590-2 PRO operates on 50V internal rails, generating a staggering 6400 mW at 50 Ohms. The integrated Pre-Gain system on the rear panel allows for hardware gain adjustments from -18 dB to +18 dB. This enables the audio engineer to perfectly align the gain staging with their monitors, eliminating inherent noise and maximizing signal resolution.
