Clearaudio Balance V2 Phono Stage
Frequently Bought Together
Product Overview & Specifications
The Clearaudio Balance V2 is a high-performance, fully balanced phono preamplifier designed to bridge audiophile-grade precision with effortless operation. Housed in a precision-milled aluminum chassis—available in silver or anodized black—it features an external power supply in a matching aluminum casing to isolate sensitive phono circuits from unwanted electrical interference.
Equipped to handle both Moving Magnet (MM) and Moving Coil (MC) cartridges via a simple selector switch, the Balance V2 automatically harmonizes input parameters for optimal cartridge matching. Ultra-precise RIAA equalization achieves an accuracy within ±0.1 dB using passive filter architecture. Connections include gold-plated RCA inputs/outputs, balanced XLR inputs/outputs, and an integrated 6.3 mm headphone output for dedicated personal listening.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- Dual Chassis Isolation Architecture: Features an external, dedicated power supply enclosed in a matching aluminum chassis to prevent transformer hum and power-line interference.
- MM/MC Auto-Harmonization: Bottom-mounted toggle switch selects between MM (+46 dB) and MC (+66 dB) gain modes, automatically adapting to high-end phono cartridges.
- High-Precision RIAA Equalization: Utilizes two passive filter stages to achieve an exceptional RIAA equalization accuracy within ±0.1 dB.
- Switchable Subsonic Filter: Bottom-mounted 20 Hz (-6 dB/octave per channel) filter attenuates ultra-low-frequency noise and tonearm resonance.
- Fully Balanced Input & Output Topology: Features both unbalanced RCA and balanced XLR inputs and outputs, preserving low-level signal integrity across long cable runs.
- Integrated Headphone Amplifier: Front-panel 6.3 mm (1/4") headphone jack supported by manual volume control, mute button, and automatic operation modes.
