SPL AUDITOR – Headphone amplifier with 120V technology
Puristic design with high-performance sound quality
The SPL AUDITOR is a headphone amplifier based on SPL's proprietary 120V technology – the same foundation as the well-known Phonitor series. The AUDITOR is designed with a straightforward and functional concept that focuses on a clean signal path and high performance. It is compatible with all dynamic headphones from 30 ohms and up, making it suitable for both professional and hi-fi contexts.
Advanced signal processing
With a frequency response from below 5 Hz to over 200 kHz, low total harmonic distortion (THD) and a dynamics of up to 129 dB at a 600 ohm load, the AUDITOR offers exceptionally transparent sound. The electronically balanced XLR input and 6.35 mm TRS headphone output enable high-quality connectivity and output.
Construction and power supply
The amplifier delivers up to 1.7 W at 600 ohms and 360 mW at 30 ohms, ensuring high capacity even at low impedance. The robust metal chassis construction is complemented by international power compatibility and low power consumption, making it a sustainable choice in both studio and home environments.
