A Tour of the iMultiMix16 USB

iPod Section

The iPod section contains the controls for your iPod. With the

iMultiMix USB you can not only play content from your iPod, but

you can also record your mix directly to it. Please note that not all

iPod models are compatible for playback and recording from the

iMultiMix USB – check the compatibility chart on page 26 for

more information.

1) BACKLIGHT

Pressing this button turns your iPod’s backlight on for 30 seconds,

if it is off.

2) LED Meters

These meters monitor the level of the input signal sent to your

iPod. This is the signal that your iPod will record. The meters

show the signal after the Limiter, if it has been engaged.

3) LIMITER

This button engages the stereo Limiter. Since there is no way to

adjust the level of your mix once it has been recorded to your

iPod, it is important that the recording is loud, but still clear and

undistorted, before entering your iPod. The Limiter prevents the

audio signal sent to your iPod from clipping, thereby allowing you

to boost up the recording level without worrying too much about

distortion. However, it is still possible to overdrive the Limiter

circuit with too hot of a signal, resulting in an unpleasant

“pumping” sound or, at the extreme, distorted recording. It is

important that you avoid this by listening to the iPod Rec Monitor

signal before it enters your iPod in case the LIMITER is producing

unwanted artifacts. Adjust the iPod RECORD LEVEL fader so

the recording is loud, yet still retains a good dynamic range.

4) iPod Control Buttons

These buttons are used for your iPod’s navigation controls. They

work just the same as they do on your iPod. You will notice that

there is an additional control here which does not appear on your

iPod – the REC MODE button. When you press this button, your

iPod will enter the recording menu. To begin recording, press the

ENTER button while in the recording menu. The red LED above

the REC MODE button will illuminate while recording.

5) Jog Wheel

The jog wheel works as your iPod’s touchwheel control.

6) iPod RECORD Fader

This fader adjusts the gain of the input signal sent to your iPod.

Generally, aim to adjust this control such that the level going to

the iPod (as shown on the iPod LED meters) is consistently

yellow. This will allow for maximum recording resolution with a

minimum of distortion or unpleasant Limiter artifacts.

The recording feature will

record the stereo audio signal

from the Main Mix directly to

your iPod.

f you listen ca

efully to your

recordings made with 5

generation video iPods, you

may hear some low-level

chirping sounds. These

sounds are made by the

iPod’s spinning hard drive

Flash-based iPod Nanos do

not exhibit this noise.
