Three tabs for steel wires (not included) for a single hang point. The tabs must be bent up before use. The Ashby-5C and Ashby-8C have separate pendant models. See “Ashby Pendant Dimensions” on page 25. You can order Ashby pendants using the following part...
(see below). Figure 16: Ashby-5C (top) and Ashby-8C (bottom) speaker mounting clamp screws and Attenuation Selector 7. Before placing the grille frame on the speaker, choose an attenuation setting (if the speaker has this feature).
CHAPTER 3: INSTALLING ASHBY LOUDSPEAKERS 8. Place the speaker grille on the installed speaker. Make sure to line up the grille with the magnets on the speaker. Figure 20: Installing the speaker into a bridge in the ceiling Safety Lanyard Some construction codes require a secondary support system.

GALAXY processors.The filter is a low fre- quency shelf with a 580 Hz breakpoint and 6 dB/octave slope. The gain is +6 dB for the Ashby-8C and +8 dB for the Ashby-5C. Figure 25: Filter settings Ashby-8C (top) and Ashby-5C (bottom)
APPENDIX B: ASSEMBLING PHOENIX-TO-PHOENIX LOUDSPEAKER CABLES When connecting Phoenix-equipped Ashby loudspeakers to the MPS-488HPp power supply (also with Phoenix connectors), you need a Phoenix 5-pin female to Phoenix 5-pin female cable. The following procedure documents how to assemble this cable. CAUTION: When wiring loudspeaker cables, it is extremely important to wire each pin correctly.
Although broadband pink noise has been the standard input signal for acoustic measurement and prediction, it rarely represents real-world content. Our MAPP XT measurements use B-Noise, a test signal created by Meyer Sound, that ensures the predictions obtained reflect system behavior under the most common input spectrum.
