This is a fantastic fully functioning all-solid-state line level preamplifier. Using a low-voltage, pure Class A gain circuit with direct-coupled output, the LS9 yields 12dB of overall gain. Output capability is a substantial 24V RMS from the balanced main outputs. The LS9 offers two pairs of dedicated balanced inputs, three pairs of dedicated single-ended inputs; and a full tape monitor loop (single ended in and out) is also provided. We are the original owners.
