Bogen OCS1 specifications Selecting Power Levels, Speaker Grille Installation & Removal

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 screwdriver, turn the knob until the slot points to the power level you require.

70V/100V Systems

Both power setting scales for 70V and 100V systems are labeled on the speakers. On the 100V scale, the last position clockwise is marked with a symbol. Do not use this position in 100V systems.

16Ω 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.

Speaker Grille Installation & Removal

Installation

The speaker grille fits tightly! Push the speaker grille in until it can go no further. Then, slap around the edge of the grille to seat the grille.The grille is prop- erly seated when it is flush with the edge of the bezel.

Removal

Insert a pocketknife blade between the grille and the bezel about a 1/4" deep and then gently pry the grille upwards. Do this in multiple places around the circumference of the grille to free the grille.
