HIGH
DEFINITION MONITOR
- Description
The ISP Technologies High Definition Monitor 212 speakers are a high output 3-way active speaker system with fidelity and resolution that will put many studio monitors to shame. Their light weight allows for easy transport and ground stack and their shape allows for horizontally arraying two boxes. Their outstanding midrange clarity and transient response, much better than 2-way systems, result in top-class vocal performance. When used with subwoofers, they form a potent, high fidelity front-of-house system of minimum size and maximum portability. The 3-way design vastly reduces the problems inherent in two-way designs which cause transient smearing and lack of clarity. First, to achieve high output with the low crossover point demanded by a 2-way design (typically 1.0 to 1.5 KHz), competitors use 3-inch diaphragm compression drivers. The larger path lengths involved in these larger drivers result in audible HF rolloffs (requiring large amounts of power to be pumped into them), sharp response peaks and dips, diaphragm breakups and resonance's, all of which result in transient smear, lack of clarity, and just plain bad highs. The higher crossover point afforded by a 3-way design (3 KHz) allows use of a 1.75 inch diaphragm driver, which nearly eliminates these problems. The high energy neodymium driver used actually has higher sensitivity above 10 KHz than any 3-inch diaphragm driver, so that at 15 KHz only one-quarter of the power is required compared to the 3-inch driver! Second, the dual midrange compression drivers have much higher sensitivity and virtually no cone breakup when compared to cone drivers. This results in much better transient attack, lack of compression, and resolution of detail than any 2-way or even 3-way system using cone drivers. They also allow a lower crossover point to the cone woofers than in a two-way system. Third, the use of dual 12-inch woofers results in greater output than a single 15-inch woofer. This is aided by the higher power handling and lower power compression which results: a single 15-inch woofer would need a 5-inch voice coil, to equal the performance of our dual voice coils. The smaller cones also have higher breakup frequencies than a 15-inch cone. This, coupled with the lower crossover frequency, again results in better clarity and transient performance from these dual 12-inch cones than would result from a single 15-inch cone. Standard with the system is a 3-channel, 900 Watt rms amplifier/electronic crossover that is specifically designed for use with the speaker. This amplifier features ISP’s patent pending DCAT high-current amplification technology. A cooling fan automatically switches on when needed. Fly points optional.

The
ISP Technologies High Definition Monitor 112
speakers are a high output 3-way active
speaker system with fidelity and resolution
that will put many studio monitors to shame.
Their lightweight allows for easy transport
and their shape allows for right or left
wedge use or pole mounting. Their
outstanding midrange clarity and transient
response, much better than 2-way systems,
result in top-class vocal performance. Their
high output and flat response allow high
gain before feedback when used as wedges.
Used alone, they have pleasant LF response,
and when used with subwoofers, they form a
potent, high fidelity front-of-house system
of minimum size and maximum portability. The
3-way design vastly reduces the problems
inherent in two-way designs, which cause
transient smearing and lack of clarity.
First, to achieve high output with the low
crossover point demanded by a 2-way design
(typically 1.0 to 1.5 KHz), competitors use
3-inch diaphragm compression drivers. The
larger path lengths involved in these larger
drivers result in audible HF rolloffs
(requiring large amounts of power to be
pumped into them), sharp response peaks and
dips, diaphragm breakups and resonance's,
all of which result in transient smear, lack
of clarity, and just plain bad highs. The
higher crossover point afforded by a 3-way
design (3 KHz) allows use of a 1.75-inch
diaphragm driver, which nearly eliminates
these problems. The driver used actually has
higher sensitivity above 10 KHz than nearly
all 3-inch diaphragm drivers, so that at 15
KHz, less power is required compared to the
3-inch driver! Second, the dual midrange
compression drivers have much higher
sensitivity and virtually no cone breakup
when compared to cone drivers. This results
in much better transient attack, lack of
compression, and resolution of detail than
any 2-way or even 3-way system using cone
drivers. They also allow a lower crossover
point to the cone woofer than in a two-way
system. This lower crossover frequency again
results in better clarity and transient
performance from the 12-inch cone than would
result with a two way box. Standard with the
system is a 3-channel, 700-Watt rms
amplifier/electronic crossover that is
specifically designed for use with the
speaker. This amplifier features ISP’s
patent pending DCAT high-current
amplification technology. A cooling fan
automatically switches on when needed. Fly
points optional.
