Hi Joe, >The delay board we are going to be using is adjustable for 64, 128, 256, 512 or 1024 milliseconds of delay. (NHRC-DAD board).
That delay board uses the MX609 Delta Modulation CODEC, a device with a S/N ratio of 30-35 dB (at the highest sampling rate; varies with frequency) and a frequency response of 300-3400 Hz (MX-COM document 20480069.004). ICS (_www.ics-ctrl.com_ (http://www.ics-ctrl.com) ) sells the S-COM-designed DADM, a delay board with a S/N ratio of 60 dB and a frequency response of 30-5000 Hz. It's also cheaper. 73, Bob Bob Schmid, WA9FBO, Member S-COM, LLC PO Box 1546 LaPorte CO 80535-1546 970-416-6505 voice 970-419-3222 fax www.scomcontrollers.com **************************************See AOL's top rated recipes (http://food.aol.com/top-rated-recipes?NCID=aoltop00030000000004)
