Introduction
Thank you for choosing the Adastra SC series 100V indoor ceiling speakers as part of your sound
reinforcement system. Please read and keep this manual for future reference.
Installation
The SC series column speakers are supplied with a top and bottom bracket for mounting to
a wall or upright support. The top bracket can be extended to allow a downward angle if
mounting at height. Lateral adjustment is afforded by pivoting the speaker on the brackets.
The rear of each SC series column speaker is fitted with a speaker wire. Connect this wire
to the output of a 100V amplifier by linking the white core to “100V” (or +) and the black
core to “COM” (or -). If extending this cable, be sure to use 2-core double-insulated cable
which is the same power handling as the speaker wire or higher.
The rear of the column speaker also has a rotary volume adjustment, which can be
set to a number of “Wattage” settings. These will set the maximum power for the
column speaker at 100V. Alternatively, the speaker may be switched to a low
impedance setting for use with a standard (non-100V) amplifier. For SC16V, the
impedance is 8Ω and for SC32V it is 4Ω. Check the amplifier manual for correct
impedance and do not exceed the RMS power rating of the column speaker.
