High-performance 2-channel preamplifier offering ultra-low distortion and wide frequency response, equipped with balanced and unbalanced inputs and outputs, plus remote control functionality.
The Benchmark LA4 is a precision stereo line amplifier designed for professional audio applications. Featuring two channels, this preamplifier delivers an exceptionally wide frequency response from 0.1 Hz to 500 kHz with minimal deviation, ensuring accurate signal reproduction. It achieves an ultra-low total harmonic distortion of less than 0.00006%, and maintains a signal-to-noise ratio exceeding 135 dB unweighted, providing clean and transparent audio output. Connectivity includes dual stereo balanced XLR and unbalanced RCA inputs, alongside stereo and mono XLR and RCA outputs. Additional rear panel I/O includes two 3.5 mm bidirectional 12 V trigger ports for integration flexibility. The unit supports a maximum input level of 20 Vrms and outputs line-level signals at 20 Vrms with a 60 Ohm impedance. Power consumption is efficient, with 12 W during active use and minimal standby power draw. The compact chassis measures 8.7 x 3.5 x 8.3 inches and weighs 7.9 pounds, making it suitable for a variety of professional audio setups.
