Installation  
If the power level is known, then select it using the front-mounted selector switch  
prior to installing the OPS1. See section Selecting Power Levels.  
SUSPENSION CABLE ASSEMBLY  
1. Screw nuts onto the eye bolts all the way to  
the flange.  
2. Screw in eye bolts with captured cable sec-  
tions in to the three suspension points.

4.  
Do not overtighten.  
3. Snap loops of free end of cable sections into  
quick-snap clip.  
4. Connect quick-snap clip to anchor point or  
drop cable. Bogen’s CK10 cable kit is suit-  
able for use as the drop cable.  
SAFETY CABLE  
The OPS1 includes a safety cable suspension point for extra protection.  
The thread of the suspension point is a 1/4-20" x 1/2" thread. Bogen offers a cable  
kit as an optional accessory (CK10) that is suitable for use as the safety cable.  
IMPORTANT  
The anchor point, drop cable, and hardware used to hang the speaker must be able  
to support the speaker’s weight under all conditions. IF YOU ARE NOT SURE OF  
THE PROPER CAPACITY OF THESE ITEMS TO USE,CONSULTA STRUCTURAL  
ENGINEER. Mount only one speaker per supplied quick-snap clip.

Speaker Wiring  
Wiring is terminated at a snap-lock input con-  
nector. There are two positive and two nega-  
tive terminals to accommodate daisy chaining  
of speakers in a system. All wiring should be  
done prior to installation and then plugged  
into the rear of the OPS1.  
DAISY CHAINING  
The OPS1’s snap-lock input connector allows  
for easy daisy chaining of speakers by provid-  
ing a second terminal of each polarity. Refer to  
the figures for proper wiring for daisy chaining  
of terminals.  
SPEAKER PHASING  
Keep the same polarity terminals wired together to ensure correct phasing. In order  
to provide the best possible sound, all of the speakers in a system need to be push-  
ing out and pulling in at the same time.  
If the connections to one speaker in a system are reversed from the others, that  
speaker’s movement will be out of sync with the other speakers.This will result in a  
loss of low frequency response and will effect the overall performance of the sys-  
tem.

Selecting Power Levels  
The front-mounted selector switch is used to  
set the appropriate power level or impedance  
for your system. Using a small flat-blade screw-  
driver, turn the knob until the slot points to the  
power level you require.  
70V/100V SYSTEMS  
Both power setting scales for 70V and 100V sys-  
tems are labeled on the speakers. On the 100V  
scale, the last position clockwise is marked with  
a
(not available) symbol. Do not use this posi-  
tion in 100V systems.  
16SYSTEMS  
The fully counterclockwise position of the setting switch is the 16-ohm position.This  
setting is suitable for use with low-impedance amplifiers that typically support 4- or  
8-ohm speakers.The speaker’s higher,16-ohm impedance makes it easier to combine  
multiple speakers into series - parallel networks while keeping the total system  
impedance at a level suitable for low-impedance amplifiers.  
25V SYSTEMS  
The OPS1 will operate on 25V systems, but at  
reduced power levels. The chart to the right  
shows the conversion from a 70V power setting  
to the actual 25V power level.

Accessory  
CK10 (CABLE KIT, 10’)  
The CK10 is a 10-foot cable with one looped end, a forged eye bolt (with 1/4-20" x  
1/2" thread), and an adjustable cable clamp. It is suitable for use as a drop cable or  
safety cable.
