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, depend-
ing 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 memory
stick. 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 most
USB sticks will be set to record 16 bit at up to 48kHz sample rate. The bit depth will be set
automatically, the sample rate can be set manually. Higher sample rates can be used (up to
96kHz) for recording direct to USB memory, the number of channels will be reduced from 16
to 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 dis-
played try formatting the memory to reset the cluster size and re-test the memory speed.
