Bogen NEAR ORBIT OPS1 - Manual (Page 6)

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.
1 6 Ω Ω SYSTEMS
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.
