ARRAY SUSPENSION
ShowMatch DeltaQ array loudspeakers are shipped with integrated link-bar suspension hardware. The suspension
system is designed to allow fast set up of typical concert-touring or fixed-installation arrays of up to 24 full-range or
18 subwoofer modules while maintaining a 10:1 safety factor when used with Bose ShowMatch Array Frame suspension
accessories.
Note: Always confirm safe working load limits with exact array configurations, pitch angles, and connection points
using either Bose Modeler or Bose Array Tool software.
Note: Bose ShowMatch loudspeakers and suspension accessories are intended for installation by professional
installers only!
Note: All lifting operations require two individuals positioned on each side of the loudspeaker.
Refer to PRO.BOSE.COM for additional product installation and setup information.

Connect Array Frame or T-bar Array Frame to Full-range Module
The ShowMatch Array Frame (SMAF) contains four connection points for subwoofer modules (all four corners), and
three connection points for full-range modules (two front corners and a center location). Each side rail provides 21
suspension points, labeled according to the image printed on the frame. The center rail provides seven suspension
points and is expandable to up to 45 points using the Multipoint Bracket Accessory (SMAFMP). For more information
about the Multipoint Bracket Accessory, see PRO.BOSE.COM.
The ShowMatch T-Bar Array Frame (SMAFT) contains three suspension points for full-range array modules (two front
corners and rear center). The center rail provides seven suspension points and is expandable to up to 45 points using
the Multipoint Bracket Accessory. The T-Bar Array Frame is compatible with full-range modules (SM5, SM10, and SM20)
only. Do not use the T-Bar Array Frame with subwoofer modules (SMS118). To create an array with subwoofer modules,
use the ShowMatch Array Frame.
The Array Frame and the T-Bar Array Frame each include two (2) shackle adapters to attach the frame to chains or
standard shackles, and four (4) quick pins to connect an array module to the frame. To create a narrower array, remove
the side end caps and tethered quick pins that are factory-installed on each loudspeaker module, and use the optional
Short Quick Pin Accessory Kit (SMQPS). For more information about the Short Quick Pin Accessory Kit, see
PRO.BOSE.COM.
To connect a ShowMatch Array Frame or T-Bar Array Frame to a full-range loudspeaker module:
1.
Use Bose Modeler software or the Bose Array Tool to determine appropriate suspension points on array frames for
required aiming angles and to confirm that array does not exceed load limits of frame. For more information
on Modeler and the Bose Array Tool, see PRO.BOSE.COM.
2.
Place array frame directly under chain motors.
3. Attach included frame shackle adapters to array frame at suspension points determined by software.
4. Lower chain motors and attach chains to shackle adapters installed on array frame.
5. Raise array frame to a height slightly greater than that of the first (top) module to be installed.
6. With one person per side, place first module directly under suspended array frame.
7.
Raise the links on module: Remove the pins, slide the link switch from the STOW position to the LINK position,
and replace the pins. See Fig. 1.
