By modern standards, the Lexicon PCM 41 didn't offer a lot of delay capability — 800 ms at the extended 6 kHz mode, or 200 ms at its 16 kHz "full bandwidth" setting. However, its great sound and versatile feature set took it well beyond that found on the typical digital delay. Certainly, it could handle basic chores such as speaker delays in P.A. systems. However, added touches such as input/delay mixing with recirculation (feedback), switchable polarity inversion of the feedback and delay signals, high/low pass filters and a full-on VCO section made it popular with studios, live mixers and musicians, for creating effects ranging from echo, double tracking, vibrato, phasing, flanging, resonant vocal sounds and more.
