INTRODUCTION TO THE ICE-16

Background Overview: The Allen & Heath ICE-16 was designed to make life easier when it comes to recording multiple audio sources. Experience of struggling with boot-up and set up times when recording to a laptop at shows, and choosing the right converter unit made us think that there is a real need for a straightforward multi-channel analogue input capture unit that is both easy to use and high quality. So the ICE-16 was born. ICE-16D incorporates fully balanced inputs and outputs on D-Sub 25pin connectors using industry standard pin assignment.
Multi-application: The primary aim for the ICE-16D was to capture multiple channels of audio from an analogue mixer or other source of line level audio signals but it has so many more application possibilities. In addition to recording straight to a USB memory device, the ICE-16D can stream multi-channel audio in high resolution 24 bit, up to 96kHz sample rate, to and from a computer so you can use the ICE-16D in a studio environment as well as live sound or event recording. In fact, if you were wondering where the name ICE came from, here is the explanation:
Interface  – Capture – Expand
Interface: The ICE-16D can function as a multi-channel analogue to digital and digital to analogue converter, connecting 24 bit audio at up to 96kHz sample rate to a computer via either IEEE1394 FireWire or USB-2.0. This is ideal for studio environments where analogue signals are converted and sent to a computer for recording to a Digital Audio Workstation (DAW).
Capture: Record 16 channels of audio in either 16 or 24 bit resolution (depending on the USB memory speed) at up to 48kHz sample rate, (96kHz with 8 channels) directly to a USB memory device—either a USB hard drive or memory stick.
The recorded file format is .wav.
Expand: You can link ICE-16D units together in different ways. You can daisy chain two units together using the FireWire ports in order to expand the number of channels connected to a computer. Or you can link two or more units together using the Sync ports in order to synchronise more than one ICE-16D when recording multiple channels,

RECORDING DIRECT TO USB MEMORY

QUICKSTART Plug in your USB hard drive or USB memory stick (see www .allen-heath.com for verified memory devices).

Format the memory device by pressing
DEL+REC for 1 second. The display will show “For” and the dots will flash. The memory will be tested (display “tst) and the ICE-16 will automatically be set to either 24 bit (“Hi”) or 16 bit (“Lo”) mode depending on the memory quality. Check the sample rate the recorder is set to by pressing & holding TIME. The set sample rate will be displayed. For 16 channel recording this must be either 44.1 or 48kHz. Select the sample rate by continuing to hold TIME and pressing either PREV or NEXT. If you choose 88.2 or 96kHz then only channels 1-8 will be recorded. Press REC to start the first recording. The display will rotate segments and show the Song (or recording) number and the Record LED will be lit red. Press START/STOP to stop the recording then REC to stop and start the next one.
Remaining time in minutes is displayed every 10 seconds (maximum 99 is displayed).
RECORDING DIRECT TO USB MEMORY
Please read these important notes regarding ICE-16D and USB memory devices.
Functional Overview:
There are no drivers required for this functionality—ICE-16D is ready to record to USB memory straight out of the box.
One of the first things to say is that USB memory devices have variable performance, depending on type and manufacture. The good news is that modern USB memory devices are now much faster and able to cope with the demands of writing high quantities of data reliably. It is important to understand however, that some USB memory, especially some sticks, will not meet the performance requirement for reliable operation, this is mainly due to the write speed.
Please refer to a list of tested USB memory devices on the www.allen- heath.com website, on the product pages for ICE- 16D.
Capability Description:
ICE-16D can record standard wave (.wav) files to either a USB 2.0 hard drive or memorystick. The resolution will depend on the write speed of the memory. In general, USB hard drives will achieve the highest resolution of 24 bit at up to 48kHz sample rate, while mostUSB sticks will be set to record 16 bit at up to 48kHz sample rate. The bit depth will be setautomatically, the sample rate can be set manually. Higher sample rates can be used (up to96kHz) for recording direct to USB memory, the number of channels will be reduced from 16to 8.
Connecting USB Memory
Plug in your USB memory device into the USB DRIVE port on your ICE-16D. Doing this will disconnect any computer connection plugged into any of the FireWire or USB ports on the rear-panel. You cannot record direct to USB memory and stream audio to a computer at the same time.
Formatting USB Memory
ICE-16D will check the USB memory device each time it is connected. Previously formatted devices will not be tested, and any recorded songs will be displayed numerically. If the memory device is new and unformatted, ICE-16D will test it and display either the resolution mode Hi or Lo depending on the test result, or display Slo if the memory device does not have sufficient speed to cope with the data rate with the memory format. This may well be because the cluster size is set to 4, 8 or 16kbytes. It needs to be 32kbytes. Formatting the USB memory on the ICE-16D will correct this. So if the initial test results in Slo being displayed try formatting the memory to reset the cluster size and re-test the memory speed.

More notes on USB memory recording user interface
Slow Memory write speed (Display Slo)
If you get the Slo message when a new USB memory device is inserted, try re- formatting the device using ICE-16D. Press and hold DEL + REC then confirm the formatting with the PLAY/STOP key. ICE will set the cluster size correctly and re-test the memory speed. If, after re-formatting, the Slo message is displayed again, then the memory device should not be used.
The Formatting process normally takes around 30 seconds, but could take longer depending on the speed and size of the memory.
24 bit vs 16 bit resolution (Display Hi or Lo)
USB Hard drives are generally faster than USB stick memory devices and allow ICE-16D to record in Hi resolution 24 bit mode. USB stick memory, although convenient will usually be automatically set to 16 bit resolution .
USB memory recording sample rate (Display 44.1, 48.0, 88.2 or 96.0)
For recording 16 channels simultaneously, the sample rate must be either 44.1kHz or 48kHz.
You can check the sample rate by holding down the TIME button.
You can change the sample rate by holding down the TIME button and pressing either the NEXT or PREV buttons.
Warning! Doing this while recording WILL change the sample rate. It is best to select it before recording and leave it set.
Note that you can select higher sample rates of 88.2kHz and 96kHz, but only 8 channels will be recorded at these rates.
USB memory recording dropouts (Display dxx)
If there is a problem with the USB memory speed or quality, an interruption or dropout may occur. This could be for an undefined number of samples. Should this occur the message dxx will be displayed momentarily (xx is the current number of dropouts that have occurred during the recording). At the end of the recording, the finalisation process may take a little longer and the message dxx will be displayed showing the total number of dropouts during that recording. This message will not be displayed if another song or recording is selected.
To avoid dropouts use a good quality USB hard drive preferably, or a fast USB memory stick of a type validated by the Allen & Heath test team. (see www .allen-heath.com)
Recording Time (Display rxx)
The time remaining will be displayed when TIME is pressed once (if over 99 minutes 99 will be displayed). The display will count down the seconds from 99 seconds remaining and when the memory is full, the display will flash “Full”.
RECORDING DIRECT TO USB MEMORY
Notes on USB memory recording file structure
After formatting, the file structure on your USB memory device will look like this when connected to your computer (removed from ICE and plugged into your computer): The recorder.ini file stores the initialisation settings for the device. Do not modify this file!
The Music folder is where you can copy .wav files to for playlist playback, for example if you require background music at an event or wish to listen to an individual or consecutive list of .wav audio files.
The Records folder is where your ICE-16 recordings are stored, under sub folders Song _01 for the first recording, Song_02 for the second and so on.
The individual channel .wav files will be named chan-01.wav to chan_16.wav.
You can copy or import these to your DAW system for mixing and editing, or you can play them back to the individual outputs on the ICE-16D.
Note that the channel order in which the files are played to the outputs is dependent on the alpha numeric name of the file so you can re-name the files to change the order if you want to.
If you delete any files from a Song folder the remaining files will play in alpha-numeric order to the outputs from output 1 but with no gap. In other words, if you deleted chan_01.wav from the folder above and played the song on ICE-16D then chan_02 to chan_16 would play to outputs 1 to 15.

PLAYLIST MODE

You can use ICE-16 to play audio music files (.wav) from the Music folder on your USB memory device for situations such as background music, pre-show & interval music, sound effects, or situations where a very large amount of consecutive audio needs to be played.
The stereo .wav files will be played to outputs 1 & 2.

Enter Playlist mode by pressing TIME +NEXT simultaneously and holding them for

1 second.
You can choose to play songs individually (stop after each) or continuously (one after another) by pressing and holding PLAY/STOP.
The first dot indicates continuous play mode.
Press & hold TIME & NEXT for >1 second
Press & hold PLAY/STOP for >1 second
Use the PREV & NEXT buttons to select (or pre-select if playing) a song.
Note. Each time you select and play a new song remember to hold down PLAY/STOP for 1 second if you wish to remain in continuous play mode.
In continuous play mode, at the end of the last song or track in the music folder, the player will start to play the first song or track in the folder.
To exit Playlist mode and enter Record mode either press TIME + NEXT at any point, or stop the playback and press REC to start a recording.

SYNCHRONISING MORE THAN ONE ICE-16D

Overview:
This feature allows two or more ICE-16 or ICE-16D units to be connected together in order to synchronise the audio files being recorded to USB memory. The ICE-16 has two 8 pin Mini DIN sockets (SYNC IN & OUT) on the rear panel for this purpose. You will need a Mini DIN 8 pin lead of not more than 2 metres in length for each unit to be synchronised to the master unit. The lead must be a pin to pin type with all 8 pins connected internally (these cables are easily available from audio equipment specialists or electronic component suppliers, and incidentally they are the same type used to control dual DJ CD players).
If you have difficulty sourcing a lead locally, you’re A&H dealer should have one in stock The A&H part number is AH9556.
When connecting ICE-16 or ICE-16D units via the SYNC ports, one unit will act as the master unit and control the transport controls (Record/Start/Stop) on the connected slave unit or units. The subsequent recorded audio files on USB memory will have the same start point and will be synchronised for each Song recording.
Requirements:
It is important that a few basic rules are followed when using the ICE-16 sync feature:

• Select good quality USB memory, preferably according to the list of verified devices, (see www.allen-heath.com). The devices should ideally be the same memory size.
• Ideally, format the USB memory devices on the ICE-16 units before recording.
• Ensure that there are not different numbers of Song recordings on the different USB memory devices (for example Songs 1-4 on one device and Songs 1-6 on another).
• Ensure that each ICE-16 unit is set to the same sample rate as required. (see p20).
• Make sure you have firmware version 8518 or higher loaded on your ICE-16 —see www.allen-heath.com for details and latest firmware release.

Procedure:

1. Connect the master ICE-16 SYNC out to the slave SYNC input.

2. Plug in your USB memory devices to the master and slave ICE-16 units.

3. Switch on both ICE-16s. CON will be displayed when the units are first connected. The master should display “nAS” alternating with the Song number.

4. The slave unit should display “S-x” where x is the slave unit number, alternating with the Song number.

5. Press REC on the master unit to start both units in record mode.
   The master unit will display the “spinning” first segment and the song number alternately with “nAS”. Plus every 30 seconds the time remaining will be displayed.

6. The slave device will display a “spinning” first segment and the song number alternately with the slave unit number. Plus every 30 seconds the time remaining will be displayed.

7. In record mode, the transport keys on the slave unit will be locked and if pressed will display the number of the slave unit.

8. To stop the recording press PLAY/STOP. To start the next recording, wait for the record light to stop flashing (when stopping a previous recording) then press REC.

9. The audio files on the USB memory devices for each corresponding song will be stored as chan_01 to chan_16. These can be re-named as preferred when copying to a computer.

10. To delete a song, select using the PREV and NEXT keys on the master ICE-16, the song should also be selected on the slave unit (follows the master selection). Press DEL on the master and press PLAY/STOP to confirm on both master and slave units.
