• Normal record mode
In this mode an audio signal at audio input 1 is
recorded into one of the 2 memory banks S1 or S2
(depending upon the position of switch
5
).
Gate = low :
In this case the pre-listening mode is active (LED 3
is off); the audio signal at input 1 is digitized by the
ADC, re-converted by the DAC and forwarded to audio
output 4 for pre-listening.
The pre-listening mode contains an overload/ clip-
ping function: as soon as the audio signal exceeds a
predefined upper or lower threshold the LED 3 lights
up for a short moment (about 10 ms). During this time
the audio signal is not scanned and the output remains
at the last DAC value. The onset of clipping (i.e.
overload distortion) is immediately audible.
H
The sound quality in the pre-listening mode
is very poor. The quality if a signal is recor-
ded and played back is much better!
The pre-listening mode is also used to find out and
set the sampling frequency. When record mode is
entered (see below) the last sampling frequency in
pre-listening mode is used.
Gate = high:
When the gate level changes from low to high Record
is triggered and the audio signal is sampled into the
memory bank selected with switch
5
. LED 3 is now
on. Recording starts at address 0 and continues until
the last address (65 535) is reached and LED 3 turns
off. If gate turns low before the end of the sampling
memory (address 65 535) is reached the record pro-
cess stops. You can use this function to sample cho-
sen segments of sound.
• Normal play mode
In this mode a previously recorded sample in the
sampling memory (S1 or S2, depending upon the
position of switch
5
) is played back.
