Because of our commitment to providing the utmost in audio quality, the
dynamic range of the ISP-100 rivals anything currently on the market. The Audio
Precision 2 , the testing standard for digital audio equipment, resolves signals
down to –125 dBFS; at this level the ISP-100 is still performing exceptionally.
Propagation time is minimized in the ISP-100. No more than two milliseconds of
delay is introduced from any analog input to analog output
with
full processing.
The ISP-100 is flexible. A General Purpose Interface (GPI) allows multiple
system configurations to be selected without the need of a PC to control the unit.
This is accomplished through user-supplied contact closures. This interface
allows users to change system settings directly and/or scroll through various
settings.
Introduction to the ISP-100 QuickBUILD

Design Software
The Merlin ISP-100 QuickBUILD

design software is a companion to the ISP-
100 VUE-IT

setup and control software. This software allows a system
designer or installer the ability to create application specific, custom QuickMAPs
in a short period of time. These “mappings”, or audio topologies, can be created
from scratch, or, existing QuickMAPs can be loaded and then modified if you only
require a variation of a previously built map. Modifying existing maps can
obviously save a great deal of time.
When building a system in QuickBUILD

, you will be placing blocks on your
screen that represent the various processing devices available. These are
representations only, and do not contain device control objects. You will not be
able to make control changes until you are running your design in the VUE-
IT

software. Since the purpose of this software is to simply design an “audio
map”, this should not present any problems.
The QuickBUILD

software is a 32 bit application and can only be run on
Windows 95 or higher operating system. This software is designed to run
independent of the ISP-100 hardware, allowing system designs to be created
prior to receiving hardware. We do however suggest that you test any new
mappings by downloading them into to the ISP-100 hardware prior to installation
for assurance that there are no errors in the QuickBUILD

design. The
QuickBUILD

software will alert you of possible DSP resource errors during the
design phase, but we feel that testing the hardware is a prudent safety
precaution.
An additional net result of the development of this software was a more efficient
use of DSP resources, allowing for additional processing capabilities. Added to
the exceptional features of the ISP-100 hardware, we feel that this combination
will provide you with a powerful and flexible tool to cost-effectively solve many of
your installation needs.
It will be very important to understand the DSP input/output architecture of the
ISP-100 in order to fully utilize DSP resources. Please read the subsequent
section called DSP “Processing Engine” I/O Interconnect.
