Unpacking
For most of the Danley Sound Labs line we recommend that it be unpacked by two
or more people. Refer to the spec sheet for product weight. Remove tape and
open top flaps. Lay the box on its side and slide the subwoofer out. Remove
the packaging wrap.
Shipping Damage
If your subwoofer appears to have been damaged in shipping, please take clear
photographs and contact Danley Sound Labs immediately.
Inspection
Check to make sure the product is not missing hardware of any kind. If any brackets or additional accessory hardware is missing, please don’t hesitate to contact Danley Sound Labs.
Understanding the Difference
THE BOUNDRY COHERENT SUBWOOFER The BC subwoofer is another unique subwoofer alignment from Danley Sound Labs. Using woofers that combine into a single exit provides impressive punch and extension out of a single cabinet. Due to the physical size of the BC design’s center exit the boundary exhibits forward directivity which can be increased with multiple enclosures.
Section 3
Initial Set Up
What Size Amplifier to Use
Selecting the right amplifier for your subwoofer depends on a variety of
factors and uses. The owner is ultimately responsible for choosing the best
amplifier or amplifiers for the application. We recommend choosing an amp that
is rated no less than continuous and no higher than program. Please note
“Continuous” does not mean “forever”! Most subwoofer manufactures, including
Danley Sound Labs, subscribe to the AES standards for subwoofer power ratings.
Connecting to the BC Subwoofer
Your Danley subwoofer has two NL4 (“speak-on”) connectors located on a panel
on the rear of the box. With the exception of the BC415 all BC series
subwoofers are wired as passive. The two NL4 connectors are wired parallel.
The BC415 has two NL8 connectors wired parallel.

witch 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 2×2 mode. Quad-amp mode allows you to connect to each of the four
15” drivers at a 4 ohm load. To do this, connect four amp channels through the
NL8 and place the switch in 4×4 mode.

Impedance
In the biamp mode the average impedance of the woofers will be half the quad-
amp mode. Refer to the spec sheet for impedance of your subwoofer.
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
toother 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 ensurethat 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.
Are You New to Rigging?
If you are new to rigging, you should do the following:
Know the Rules for Safe Rigging.
Attend a safe rigging seminar, such as that presented by professionals like
Rigging Seminars or by Chain Motor Hoist manufacturers like Columbus McKinnon
Corp. (manufacturers of the C/M Lodestar). Meet and establish a relationship
with a licensed mechanical or structural engineer. Get in the habit of asking
them questions instead of guessing about their answers. Learn from what they
tell you. Meet and discuss this aspect of your business with your Insurance
Agent.
Research and understand the codes, practices, and requirements in the venues
where you intend to operate your sound system.
General Hardware Information
All Danley subwoofers which are intended to be flown are provided with ⅜ inch
– #16 hardware. Any hardware used in an
overhead suspension application must be load rated for the intended use.
Generally, this type of hardware is available only from
rigging supply houses; industrial supply catalogs and specialized rigging
distributors. Local hardware stores do not usually stock
these products.
Attachment to Structures
A licensed Professional Engineer must approve placement and method of
attachment to structures prior to installation of any overhead object. The
following performance standards should be provided to the Professional
Engineer for design purposes: Uniform Building Code as applicable, Municipal
Building Code as applicable, Seismic Code as applicable. Installation of
hardware and method of attachment must be carried out in the manner specified
by the Professional Engineer. Improper installation may result in damage,
injury or death.
Rigging Hardware Inspection & Maintenance
Suspension systems are comprised of mechanical devices and, as such, they
require regular inspection and routine maintenance to insure proper function
ability. Danley subwoofers must be inspected for fatigue at least annually.
The inspection shall include a visual survey of all corners and load bearing
surfaces for signs of cracking, water damage, de-lamination, or any other
condition that may decrease the strength of the subwoofer enclosure. Accessory
rigging hardware provided with or for Danley subwoofers must be inspected for
fatigue at least annually. The inspection shall include a visual material
survey for signs of corrosion, bending or any other condition that may
decrease the strength of the fastener. For other fittings used, refer to the
manufacturer’s inspection and maintenance guidelines for process. Danley Sound
Labs is not responsible for the application of its products for any purpose or
the misuse of this information for any purpose. Furthermore, Danley Sound Labs
is not responsible for the abuse of its products caused by avoiding compliance
with inspection and maintenance procedures or any other abuse. Prior to
suspending the system, an expert, trained and experienced in flying subwoofer
systems should inspect all rigging parts and components.
Operation
Acoustic Level Warning
Danley Sound Labs subwoofers can produce sound levels capable of causing
permanent hearing damage from prolonged exposure. The higher the sound level,
the less exposure needed to cause such damage. Avoid prolonged exposure to the
high sound levels from the subwoofer. Some BC subwoofers are capable of levels
in excess of 140 dBSPL! Levels this high can cause permanent hearing loss!
When operating at these high sound pressure levels the user is strongly
encourages to use hearing protection. Danley Sound Labs accepts no liability
for hearing damage from using our subwoofers!
Operator Responsibility
It is the responsibility of the operator to maintain safe operating levels and
to insure that the audience is not harmed by excessive levels. This is a chart
of the recommended exposure limits set by OSHA.
Aqua Tight Coating
Aqua Tight Coating includes full two layer fiberglass finish for maximum
moisture resistance as well as a special polyurea coat bonded to the
fiberglass exterior & two topcoat layers of UV resistant color stabilizer. It
also includes all stainless steel exterior fasteners, an acoustically
transparent moisture barrier to the grille, waterproofing the driver cones and
sealant for the input plate, handles or cabinet fixtures. The finish also
includes a powder coated stainless steel grille, sealed, waterproof cable
leads (12’ length standard), and fully caulked all external joints (except for
the “weep” opening at the bottom of the grille).If a repair is to be made on a
loudspeaker with “AT” finish, a few steps must be taken to insure the speaker
remains water resistant in future usage. The caulking must be removed to free
the grill and driver access panels. Once the repair is finalized, the bolts
must be coated with silicon and the caulk must be replaced on all panels that
have been removed.
