Introduction  
Thank you and congratulations on your purchase of QSC’s ISIS multipurpose loudspeakers. These products represent the state-of-  
the-art in lightweight SR (sound reinforcement) loudspeaker systems. To get the most from your investment, we encourage you to  
review this manual carefully.  
The ISIS 102M, ISIS 102W, ISIS 122M, and ISIS 152M loudspeaker systems are full range, high output, two-way designs deliver-  
ing superior sound quality and high SPL in a lightweight, all-weather cored composite enclosure.  
The ISIS W-102M, ISIS W-102W, ISIS W-122M, and ISIS W-152M loudspeaker systems are wooden enclosure versions and are  
essentially identical with the exceptions of weight and weather resistance. These models offer an economical alternative to the  
cored composite enclosures in high quality 13 to 18 ply baltic birch.  
EN  
Applications include flown arrays, yoke mounting, foldback stage monitors, and portable event use (pole mount). Hardware  
options make the ISIS loudspeakers versatile and easy to reconfigure for mobile and touring sound companies. These loudspeak-  
ers make an excellent choice for a wide variety of SR applications.  
Do not install wooden enclosure models in exterior environments unless fully shield from the weather.  
Product Features (ISIS 102M (handle on top) and ISIS W-102M (side recess) shown)  
Note: Models featuring cored composite enclosures have a carrying handle on their top, whereas wooden enclosure models have  
a handling recess on the side of the enclosure. A wooden enclosure is shown at the far right, below. Other views are of a cored  
composite enclosure.  
1- High-frequency driver/waveguide assembly (102W waveguide differs)  
2- Low-frequency driver  
3- Removable metal/foam grill  
4- Fly track (top and bottom of cabinet)  
5- Carrying handle  
6- Rear pick-point  
7- Connection panel with two Speakon® connectors wired in parallel and crossover mode selector switch  
8- Pole cup (bottom of cabinet)  
Note- Standard model shown. Custom product options may include hardware and connector variations.

Coverage Angles  
102M/122M/152M- These models are  
equipped with 60° conical waveguides. HF  
coverage remains constant regardless of  
cabinet orientation.  
Waveguide slot verti-  
cally oriented: (102W  
only; as shipped from  
factory)  
102W- Before mounting the loudspeaker,  
determine the mounting orientation and  
desired coverage angles. As supplied from  
the factory, the loudspeaker’s coverage  
angles are 150° (horizontal) x 50° (vertical)  
with the cabinet oriented vertically. The  
waveguide can be rotated to interchange  
the coverage angles.  
Waveguide slot hori-  
zontally oriented: (102W  
only; requires  
EN  
waveguide rotation)  
Rotating the Waveguide to Alter  
HF Coverage Pattern (102W only)  
1- Remove the grill. It is held in place by  
eight cap head screws.  
2- Remove the four waveguide retaining  
screws. A #2-size Phillips screwdriver is  
recommended.  
3- Reach into the waveguide’s port and  
pull gently to remove the waveguide. Be  
careful not to damage the connections,  
wiring, or the gasket between the  
waveguide and the cabinet. The aluminum  
spacer ring must remain in place.  
4- Rotate the waveguide 90° clockwise or  
counterclockwise and set it back in place.  
Make certain the wiring is not stressed or  
pulled loose from its connections when  
rotating the assembly.  
5- Before reinstalling the waveguide  
mounting screws, lift the assembly a small  
distance and make sure that the gasket  
and spacer ring are properly in place.  
Reposition, if required. Set the waveguide  
in place and install the screws. We recom-  
mend the use of removable thread sealant  
to prevent the screws from loosening. Do  
not overtighten.  
6- Replace the grill. We recommend the  
use of removable threadlocker to prevent  
the screws from loosening. Do not over-  
tighten.

Select the Desired Crossover Mode  
All models are equipped with a Crossover Mode switch.  
Before using, set the Crossover Mode switch to the desired  
position using a flat-tip screwdriver. The switch has a slot-  
ted shaft; insert the screwdriver tip into the slot and turn  
the shaft so the slot points to the desired mode. Do not  
change switch positions with power applied.  
FULL RANGE: This setting uses the internal crossover net-  
work. Connect the full-range input signal to Speakon pins  
1+ and 1-.  
FULL RANGE  
BI-AMP  
EN  
BI-AMP: This setting bypasses the internal crossover net-  
work and connects Speakon pins 1+ and 1- to the low-fre-  
quency (LF) driver and pins 2+ and 2- to the high-frequency  
(HF) driver. Signal processing ahead of the amplifier is  
required; the HF driver can easily be damaged if full range  
program is applied! Use a four-wire cable and an amplifier  
configured to operate in bi-amp mode.  
BIAMP OPERATION- Signal processing ahead  
of the amplifier is required; the HF driver can  
easily be damaged if full range program is  
applied!  
Make the Required Connections  
All models are equipped with two Neutrik NL4-series air-  
tight Speakon connectors. The two connectors are wired in  
parallel, allowing for multiple cabinets to be connected in  
parallel by plugging one cabinet into another with a suitable  
cable.  
Connector pinout is determined by the Crossover Mode  
switch setting. Full Range selection uses Speakon pins 1+  
and 1-. Bi-amp selection uses pins 1+ and 1- for the LF  
driver, 2+ and 2- for the HF driver. There are pinout charts  
printed on the connector plate.  
Maintain proper speaker and amplifier con-  
nection polarity throughout the entire system.  
All positive-marked loudspeaker terminals  
should be connected to positive-marked ampli-  
fier output terminals. This will provide the best  
possible low-frequency output from your sys-  
tem.  
Speakon plug pinouts- The Speakon plugs that are con-  
nected to the loudspeaker cabinets should conform to the  
pin outs shown at right. The connectors are shown from the  
wire-insertion end and show the inside of the disassembled  
Speakon plug.

Recommended Fastener Torque  
Fly track to cabinet-4.52 Nm (40 in-lb)  
Pole cup to cabinet- 1.92 Nm (17 in-lb)  
Waveguide to cabinet- 1.92 Nm (17 in-lb)  
LF driver to cabinet- 1.92 Nm (17 in-lb)  
Grill to cabinet-1.01 Nm (9 in-lb)  
Connector plate to cabinet-1.01 Nm (9 in-lb)  
EN  
All fasteners should be checked for tightness  
before loudspeaker use. If any fastener is loose  
or is removed for any reason, ensure it is  
installed using a torque-limiting tool to avoid  
cabinet damage. Fly track hardware is safety-  
critical and should be carefully checked before  
suspending or rigging the cabinet.
