Description
The MERLIN ISP-100 provides the tools
the contractors need to get the job done.
They are tools designed to make the user
successful at audio, not computer programming. The ISP-100 is designed with flexibility in mind, providing a powerful tool
which allows you to adapt to ever-changing applications.
A versatile platform utilizing the latest in
DSP technology allows the ISP-100 to
quickly adapt to new market demands and
continually changing improvements and
advancements in semiconductors.
A series of predefined, signal path topologies, called QuickMAP™s are offered,
which enable the designer to quickly define the processing structure of the system. This approach allows for a continuation of new processing solutions and/or
variations, providing “market-specific”
templates to help minimize your design time
and increase your profit. In addition, we
offer a stand alone program,
QuickBUILD™, which allows system designers to modify or create their own
QuickMAPs.
Integrated operations and functions simplify the total audio system design. Integration eliminates extensive cabling, connectors and components, along with minimized noise and failures due to cables and
solder joints. The result of this consolidation of processing is overall system performance and audio integrity being greatly
increased.
An ergonomically designed software interface called VUE-IT™ for the ISP-100 provides graphic control panels with the “conventional” look and feel of signal processors. As well, the advanced and easy-touse filter tool graphically displays the configuration of your filter block settings.
The ISP-100 is designed with modular inputs and outputs. This feature allows the
designer or installer to select between analog input or output modules and/or a digital input/output combination module. The
modules are two channel units and can be
intermixed between analog and digital providing a variety of I/O combination possibilities.
The ISP-100 supports a maximum of four
inputs with a maximum of eight outputs.
Combinations such as 2x2, 2x4, 2x6, 2x8,
4x2, 4x4, 4x6, or, for example, two in digital
by eight out analog could all be accommodated by simply varying the I/O modules
within the same ISP-100 chassis. Our
QuickMAP software topologies support
most of the configurations with more in
development continually based on market
demand.
The ISP-100 provides a dynamic range
which rivals anything currently on the
market. The Audio Precision System II (the
testing standard for digital audio equipment) resolves signals down to -128 dBFS;
at this level the ISP-100 is still performing
exceptionally. The ISP-100 noise floor measures -110 dB, typical, and maintains a
THD+N of less than 0.003%, typical. Due
to the design efficiencies, propagation time
is minimized in the ISP-100. Less than two
milliseconds of inherent delay is introduced
from any analog input to any analog output with full processing.
Another measure of the flexibility designed
into the ISP-100 is the General Purpose Inputs (GPI). GPIs allow multiple system configurations to be selected without the need
for a PC to control the unit. GPIs are programmable dry contact closure interfaces
which allow user-supplied contact closures
to switch system settings directly to a defined program and/or scroll through system settings as desired.

Specifications
The specified audio digital signal processor shall implement signal amplitude modifications via 24-bit data paths without truncation of values during processing via
three 66 MHz DSPs. Component emulation
algorithms shall be performed on the
motherboard independent of any analogto-digital, digital-to-analog and/or any digi-
ISP-100 Integrated Signal Processor
tal signal input or output. Motherboard
shall provide means to connect up to five,
two-channel, I/O modules. Any conversions to or from the digital domain of the
audio signal shall be performed by said
modules. Mathematical calculations shall
be implemented as such that resultant precision exceeds current industry standard
test equipment abilities to measure processing noise floor. The unit shall be of a design and implementation process which limits any and all signal degradation between
20 Hz and 20 kHz to signal I/O conversion.
The efficiency of the processor shall be as
such that the inherent delay of the unit will
be no more than two milliseconds from any
analog input to any analog output with
full processing.
The specified unit shall provide a single
ISP-100 Integrated Signal Processor
chassis capable of being hardware configured for 2x2, 2x4, 2x6, 2x8, 4x2, 4x4 or 4x6
signal path operation. The specified unit
shall offer 24-bit A/D and D/A converters
with a minimum noise floor of -110 dB and
no more than 0.003% THD+N. The unit
shall have a 1k measurement for THD+N
of 0.002%. The chassis shall be capable of
accepting an AES/EBU (SPDIF) digital I/O
module for signal input and output. Both
digital and analog modules shall be able to
be used simultaneously within the same
chassis in any compliant I/O configuration
as stated above.
Communication exchange between the unit
and PC shall be conducted via RS232 serial port. Unit shall provide a DB-9 connector accessible from the front of the unit
and a RJ-45 connector on the rear of the
