Echelon Delay (Mono, Stereo)

The Lexicon PCM 42 is a highly regarded digital delay unit known for its warm, musical sound and extensive modulation capabilities. Introduced in the early 1980s, it features up to 4.8 seconds of delay time, tap tempo, and a unique modulation section that allows for lush chorus and vibrato effects. Its analog-style controls and high-quality audio path have made it a studio staple, prized for both subtle ambience and creative, experimental delay textures. The PCM 42 is celebrated for its reliability, versatility, and distinctive sonic character, making it a favorite among guitarists and producers alike.
Fender Model Guide
Mono: Combines studio-quality repeats, modulation and diffusion for everything from precise rhythmic delays to expansive, reverb-like atmospheres.
- TIME Adjusts time before first repeat is heard.
- TAP DIVISION Synch delay time to the beat by selecting a subdivision of the current tempo.
- FEEDBACK Adjusts number of delay repeats.
- TIMESCALE Scales current delay time from x0.5 to x2. For example, if delay time is 200 ms and Timescale is 0.5, the perceived delay time is 100 ms. When changing Timescale, a pitch warp is induced in the sound in the delay line.
- DIFFUSION Adjusts level of diffused repeats surrounding main delay. Higher settings blur the line between delay and reverb.
- MIX Adjusts level of delay effect.
- FB INV Adjusts feedback path polarity of left and right delays.
- DELAY INV Adjusts output polarity of left and right delays.
- MULTIPLY Adjusts delay line sample and “multiplies” set delay time. X1 (OFF): Multiplies delay time by 1, high-frequency filter at 16kHz X2 (ON): Multiplies delay time by 2, high-frequency filter at 6kHz
- MOD TYPE Selects sine or triangle delay modulation type.
- MOD RATE Adjusts delay modulation speed.
- MOD DEPTH Adjusts delay modulation depth.
- HI-CUT Adds subtle low-pass filter to feedback path.
- HOLD When enabled, repeats delay buffer contents until Hold is disabled.
- SPILLOVER SWITCH Select to continue hearing delay repeats after effect has been bypassed.
Stereo: Extends Echelon Delay with advanced stereo routing and interaction between delay lines, creating complex spatial effects and evolving textures. **CONTROLS** • TIME L: Adjusts time before first repeat is heard of left delay. • TIME R: Adjusts time before first repeat is heard of right delay. • FEEDBACK: Adjusts number of delay repeats. • TAP DIV L: Selects subdivision of current tempo to use for setting effect speed for left delay. • TAP DIV R: Selects subdivision of current tempo to use for setting effect speed for right delay. • MIX: Adjusts level of delay effect. • MOD TYPE: Selects sine or triangle delay modulation type. • MOD RATE: Adjusts delay modulation speed. • MOD DEPTH: Adjusts delay modulation depth. • ST MODE: Adjusts how both delay lines interact in the stereo field. Parallel: Delay lines are independent and do not interact. Prime: Delay L and R feedback paths are summed and fed back to both delay inputs. Criss Cross: Delay feedback paths are swapped, delay L feedback path is fed into delay R input; delay R feedback path is fed into delay L input. Series: Delay L feeds directly into delay R input. Feedback paths are independent Ping-Pong: Delay feedback paths are swapped as in Criss Cross, except that input signal only feeds delay L. • TIMESCALE: Scales current delay time from x0.5 to x2. For example, if delay time is 200 ms and Timescale is 0.5, the perceived delay time is 100 ms. When changing Timescale, a pitch warp is induced in the sound in the delay line. • DIFFUSION: Adjusts level of diffused repeats surrounding main delay. Higher settings blur the line between delay and reverb. • MULTIPLY: Adjusts delay line sample rate and “multiplies” set delay time. X1 (OFF): Multiplies delay time by 1, high-frequency filter at 16kHz X2 (ON): Multiplies delay time by 2, high-frequency filter at 6kHz • FB INV: Adjusts feedback path polarity of left and right delays. • DELAY INV: Adjusts output polarity of left and right delays. • HI-CUT: Adds subtle low-pass filter to feedback path. • HOLD: When enabled, repeats delay buffer contents until Hold is disabled. • SPILLOVER SWITCH: Select to continue hearing delay repeats after effect has been bypassed.
