LM1 - Dynamic Limiter

COMPRESSOR

The LM‑1 Dynamic Limiter is a true RMS limiter in a compact diecast aluminium enclosure with black satin powder‑coat finish. It features a variable Threshold control and an Attack switch offering fast (500 µs) or slow (5 ms) settings modelled on vintage Pearce G1 and BC1 units. It uses a vintage NOS Harris CA3080 compressor IC sourced from original Pearce inventory. The unit operates on 9 V DC (center‑negative), via pedalboard power or battery, and draws approximately 200 mA. It delivers ultra‑quiet operation with a 280 kHz switching DC supply providing ± 15 V internal rails for 26 V peak‑to‑peak headroom. The LM‑1 is designed for transparent peak limiting, particularly suited to being placed in an amplifier’s effects loop to tame spikes without altering tone.
