(all models)
Thank you for the purchase of your new ISA amplifier. To get
the most out of your amplifier, review this manual carefully. The
installation, connection and operation sections provide useful
guidelines to get you up and running quickly and correctly.
The QSC shipping box should contain:
1- The amplifier
2- This user manual
3- #14AWG AC line cord with IEC connector
After you have removed the amplifier from the box, make sure
you save the box and packing material for safely storing or
shipping the amplifier in the future.
The ISA Series amplifiers offer professional-quality perfor-
mance at an affordable price. Three power-points are offered in
both directly-coupled and autotransformer-coupled output.
Output power at 2 ohms ranges from 430 to 1200 watts per
channel.
The ISA amplifier was designed to fit your installed sound
requirements. The detented gain controls, located on the rear
panel, provide accurate, repeatable adjustments. Each channel
has defeatable clip limiting and selectable-response low
frequency filters. QSC’s rear-to-front airflow cooling helps to
keep other system components in the equipment rack cooler,
enhancing overall system reliability.
For those systems with QSC DataPort accessories (DSP,
crossovers & filters, remote cinema monitoring) a DataPort V2
(version 2) is included on all ISA models. Consult your QSC
representative for accessory compatibility information.
The ISA amplifiers are easy to use. All operating mode
switches are grouped together on the rear panel. A mode
switch configuration chart is printed directly on the rear panel for
easy, accurate reference. This helps to avoid configuration
problems. On the autotransformer-coupled “T” models, separate
screw-terminal output connections are provided for both low
impedance loads and high impedance (25/70/100 volt) loads.
The “connectability” of the “T” models makes them simple to
use in almost any installed sound application.
The ISA amplifiers are built for long service life. XLR and
terminal block input connectors provide tight, noise-free
connections. The chassis design incorporates robust output
cable dressing tie-down points to keep stress off the connec-
tions, making them more reliable. All signal processing is done in
side loops and then returned to the main signal path. This
maintains high signal fidelity and provides a more robust system.
Your new ISA amplifier will give you many years of great
sound. It is the best value in installed sound amplification with
legendary QSC durability and performance.
