BH Series Indoor / Outdoor Background Speakers - Supplied in Pairs

Introduction

Thank you for choosing the Adastra BH series speakers for your sound installation.

These durable cabinets deliver reliable, high quality sound output for music and announcements. Please read the following guidance notes for correct installation.

Installation

1. Unscrew the plastic wall plate from the speaker bracket and mark out, drill and fix to the wall as required.

2. Line up the steel speaker bracket against the plastic wall plate at the required tilt angle and secure using the 2 screws provided through 2 of the punched holes.

3. Locate the speaker into the speaker bracket and secure using the screw caps provided on the top and bottom.

4. Adjust the horizontal angle (pan) of the speaker by loosening the screw caps, turning the speaker and re-tightening the screw caps.

5. Remove the cover on the rear of each speaker to reveal the spring terminals.

6. Each BH speaker has 8Ω impedance. Ensure the total load connected to each output channel is no lower than the minimum stated for the amplifier. Connect 1 BH speaker for an 8Ω load or connect 2 x BH speakers in parallel for a 4Ω load.

7. Use good quality 2-core speaker wire capable of carrying the rated power and connect to the speaker terminals. Strip back the insulation, press down the terminal, thread the wire through the terminal post and release to grip the bare wire.

8. If installing in sheltered outdoor areas, fit the cover over the rear terminal cavity to protect the wiring from moisture.

9. Connect the + and - terminals on the speaker to the relative outputs on the amplifier as shown in the diagram above.
