adastra 952.241UK Indoor Column Speakers 100V

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.
