About the Line 3

The Sonic Frontiers Line 3 is a reference-grade, dual-chassis tube line preamplifier using a separate outboard power supply and a fully dual-mono topology for very low noise and high channel separation. It provides multiple single-ended and balanced line-level inputs and outputs (including tape loop and surround/processor loop), remote control, and flexible configuration via its front-panel display and logic control system. The design focuses on neutral, transparent sound with wide bandwidth (specified 2 Hz to 250 kHz) and very low distortion (0.01% THD), achieving a 100 dB signal-to-noise ratio on line inputs. Its valve complement is 10 x 6922 and 2 x 6GH8A tubes, and it is supplied with an infrared remote control. The Line 3 does not include an onboard headphone amplifier and is strictly a line-level preamplifier to feed power amplifiers.
