Setup - E-Mu ESI-32 Operation Manual

5. Setup

Tip: The optimum gain level setting for
ESI-32 is +00. For high-quality sampling,
use an external microphone preamplifier
such as the one built into your mixer. The
mic preamp in the ESI-32, while acceptable
for some applications, is not designed to be
used for ultra-critical sampling.
!
Caution: When sampling in stereo, the
Threshold circuit only reads the left channel
to initiate sampling.
Tip: The ESI-32 actually begins
sampling just before the threshold is
exceeded in order to preserve the attack
transient. (Presampling times are set for
12mS at 44.1kHz and 17mS at 22050Hz)
Tip: If the digital interface card is not
installed in the ESI-32, the digital sampling
options will not appear in the display.
In this submodule, you will prepare the ESI-32 for sampling. Either the
analog inputs or the optional digital input can be sampled.
1. Activate Sample module. If you want to sample into the sample
number shown on the display, you need do nothing except proceed
to the next step. To sample into a different sample number, refer to
0. Select Sample.
2. Select Submodule 5.
3. Use the cursor buttons to select one of the following parameters
to edit. Page one displays:
SETUP
Thresh:
L: On
R: Off
• Gain: Set the analog sample level with the data entry control so that
the left and right side meters indicate optimum sampling level. Play
the sound to be sampled and observe the bar graph display. The
signal level should be set so that the peak bar comes close to the
extreme right side without actually reaching it. The gain is
adjustable from -16 dB to +40 dB in 4 dB steps. This control has no
effect on the digital input.
• Thresh: (Threshold) Set the sampling threshold with the data entry
control. If you arm sampling (7. Arm Sampling) and the signal to be
sampled exceeds the threshold, sampling will begin.
• L: (Left Channel) Line three shows the left input level, record status,
and whether on or off. Press Yes or No to enable or disable recording
into the left channel. When sampling into one channel only, turn off
the other channel to conserve memory.
• R: (Right Channel) Line four shows the right input level, record
status, and whether on or off. Press Yes or No to enable or disable
recording into the right channel. When sampling into one channel
only, turn off the other channel to conserve memory.
4. Select page two by pressing the right cursor button. Page two
shows:
Source: analog 44100
Length:
200.8secs Available
• Source: Choose between 22050 Hz and 44100 Hz when using the
analog inputs. When a digital interface card is installed, three more
options, S/PDIF 32K, 44.1K or 48K will appear in the display. When
using the digital input, the display setting should match the sample
rate of the incoming digital data, otherwise the sample will play back
at the wrong pitch.
