Switch Modes for BC415
This subwoofer can be operated one of two ways; Bi-amp or Quad-amped. Bi-amp mode allows you to connect to two pairs of
the four 15”
drivers with an 8 ohm load. To do this, connect two amp channels through the NL4 and place the switch in 2x2
mode. Quad-amp
mode allows you to connect to each of the four 15” dr
ivers at a 4 ohm load. To do this, connect four amp
channels through the NL8 and place the switch in 4x4 mode.

Rigging
If you have to ask how, you probably shouldn’t be doing it!
Safety Precautions
Before attempting to rig or suspend your Danley speakers, read and understand the following safety information.
IMPORTANT RIGGING SAFETY WARNING!
The information in this section has been assembled from recognized engineering data and is intended for informational purposes
only. None of the information in this section should be used without first obtaining competent advice with respect to applicability
to a given circumstance. None of the information presented herein is intended as a representation or warranty on the part of
Danley Sound Labs. Anyone making use of this information assumes all liability arising from such use.
All information presented herein is based upon materials and practices common to North America and may not directly apply to
other countries because of differing material dimensions, specifications, and/or local regulations. Users in other countries should
consult with appropriate engineering and regulatory authorities for specific guidelines.
Correct use of all hardware is required for secure system suspension. Careful calculations should always be performed to ensure
that all components are used within their rated workload before the array is suspended. Never exceed maximum recommended
load ratings.
Before suspending any speaker system always inspect all components (enclosure, rigging frames, pins, etc.) for cracks,
deformations, corrosion, missing, loose or damaged parts that could reduce strength and safety of the array. Do not suspend the
speaker until the proper corrective action has been taken. Use only load- rated hardware when suspending Danley subwoofers.
