Analog
Analog delay was the method originally used to electronically duplicate a tape delay. It is characterized by the way each repeat degrades or
deteriorates from the original input signal.
Delay
Delay is an effect that will record a portion of the incoming signal, and then play it back a short time later. It can repeat the recording
several times, or just once. This type of effect is also referred to as an echo because it basically echoes the original signal. This is a full band
width digital delay with no degradation of repeats.
Ping Pong
A ping pong delay is an effect that will record a portion of the incoming signal, and then repeat the recording a short time later. When it
replays the recorded signal, the repeats will bounce from side to side (in stereo). This is why it is called ping pong, because the repeats will
go back and forth from side to side.
Delay - Adjusts the volume of the delay effect.
Feedback - Adjusts how many times the delay will repeat the signal.
Tap It - The Tap It button is used to set the delay time, or the amount of time between repeats. Tapping this button in time with
the music will align the repeats of the delay in synchronization with the beat of the music. Pressing and holding the Tap It
button down for a few seconds will select the fine tune adjustment of the delay time using the Select knob. Press any
button to exit.
Reverb Effects Group
The Marquis JM60/JM120 have three different reverb types to choose from. Each successive press of the Reverb Select button will advance to
the next type of reverb. The reverb effect may be bypassed by pressing and holding the Reverb Select button down. The only adjustable
parameter for the reverb effect group is the level. The following is a description of each reverb type:
