1. Safety precautions

1.1. Information regarding the use of loudspeakers

Potential risk of personal injury

Never stand in the immediate vicinity of loudspeakers driven at a
high level. Professional loudspeaker systems are capable of
causing a sound pressure level detrimental to human health.
Seemingly non-critical sound levels (from approx. 95 dB SPL) can
cause hearing damage if people are exposed to it over a long
period.

In order to prevent accidents when deploying loudspeakers on the
ground or when flown, please take note of the following:

– When setting up the loudspeakers or loudspeaker stands,

make sure they are standing on a firm surface. If you place
several systems on top of one another, use straps to secure
them against movement.

– Only use accessories which have been tested and approved

by d&b for assembly and mobile deployment. Pay attention to
the correct application and maximum load capacity of the
accessories as detailed in our specific "Mounting instructions"
or in our "Flying system and Rigging manuals".

– Ensure that all additional hardware, fixings and fasteners used

for installation or mobile deployment are of an appropriate
size and load safety factor. Pay attention to the manufacturers'
instructions and to the relevant safety guidelines.

– Regularly check the loudspeaker housings and accessories for

visible signs of wear and tear, and replace them when
necessary.

– Regularly check all load bearing bolts in the mounting devices.

Potential risk of material damage

Loudspeakers produce a static magnetic field even if they are not
connected or are not in use. Therefore make sure when erecting
and transporting loudspeakers that they are nowhere near
equipment and objects which may be impaired or damaged by an
external magnetic field. Generally speaking, a distance of 0.5 m
(1.5 ft) from magnetic data carriers (floppy disks, audio and video
tapes, bank cards, etc.) is sufficient; a distance of more than 1 m
(3 ft) may be necessary with computer and video monitors.

2. Y7P/Y10P loudspeaker

2.1. Product description

Y7P/Y10P are passive 2-way loudspeakers housing two 8" LF
drivers and a 1.4" HF compression driver with a rotatable CD horn
producing a nominal dispersion (h x v) of 75° x 40° or 110° x
40°, respectively. The frequency response extends from 59 Hz to
above 18 kHz.

The two 8" neodymium LF drivers are positioned in a dipolar
arrangement providing exceptional vertical dispersion control even
at lower frequencies.

Specially designed ports with optimized flow characteristics
provide a considerably improved, efficient low frequency
reproduction.

The cabinets are constructed from marine plywood and have an
impact and weather protected PCP (Polyurea Cabinet Protection)
finish. The top and bottom panels incorporate a handle each. The
front of the loudspeaker cabinet is protected by a rigid metal grill
backed by an acoustically transparent foam.

Additional combined sockets

The cabinets accommodate fittings for three types of rigging
devices:

– A quick lock adapter plate on one side of the cabinet that

accepts the Z5397 YP Swivel bracket.

– Two M10 threaded inserts on the top and bottom panels each

to accept the Z5399 YP Mounting bracket.

– Two additional combined sockets [A], one in the top panel

and one at the center rear of the cabinet that accept either:

– the Q9032 Safety eye bolt M10 to apply a secondary

safety device.

– the Z5049 Flying pin 8 mm to support single cabinets or to

secure the aiming of an array.

Intended use of the Z5049 Flying pin

WARNING!
Potential risk of personal injury and/or

damage to material!

The Z5049 Flying pin 8 mm is designed and intended for static
loads only. Therefore please observe the following:

– The Flying pin must not be used to attach a secondary safety

device.

– Ensure the Flying pin is securely locked before lifting any load.

Proceed as follows:

1. Press the button to release the locking mechanism ([r] ).

2. Fully insert the Flying pin into the respective socket.

3. Release the button to lock the pin ([l] ).

4. Recheck the Flying pin is securely locked by briefly pulling the
Flying pin towards you.

Connector wiring

2.2. Connections

The cabinets are fitted with a pair of NLT4 F/M connectors. All
four pins of both connectors are wired in parallel. The cabinets use
the pin assignments 1+/1–. Pins 2+/2– are designated to active
subwoofers. Using the male connector as the input, the female
connector allows for direct connection to a second cabinet.

The cabinets can be supplied with NL4 M or EP5 connectors as an
option.

Pin equivalents of the connector options are listed in the table
below.

2.3. Operation

NOTICE!

Only operate d&b loudspeakers with a correctly configured d&b
amplifier, otherwise there is a risk of damaging the loudspeaker
components.

For applicable amplifiers, the controller setups are available in
Dual Channel and Mix TOP/SUB mode.

2.3.1. Controller settings

For acoustic adjustment the functions CUT, HFA and CPL can be
selected.

CUT circuit

Set to CUT, the cabinet low frequency level is reduced. The
cabinets are now configured for use with actively driven d&b
subwoofers.

Frequency response correction of HFA circuit

HFA circuit

In HFA mode (High Frequency Attenuation), the HF response of the
system is rolled off. HFA provides a natural, balanced frequency
response when a unit is placed close to listeners in near field or
delay use.

High Frequency Attenuation begins gradually at 1 kHz, dropping
by approximately 3 dB at 10 kHz. This roll off mimics the decline
in frequency response experienced when listening to a system from
a distance in a typically reverberant room or auditorium.

CPL circuit

The CPL (Coupling) circuit compensates for coupling effects
between the cabinet and close boundary surfaces. CPL begins
gradually around 1 kHz, with the maximum attenuation below
400 Hz. To achieve a balanced frequency response, the CPL
circuit can be set to dB attenuation values between 0 and –9.

Positive CPL values create an adjustable low frequency boost (0 to
+5 dB) at around 65 Hz and can be set when the system is used in
full range mode without subwoofers.

Altering the HF horn dispersion

By factory default, the HF horn is fitted to the cabinet providing the
nominal horizontal dispersion when the cabinet is used in upright
position. This is indicated by a white label on the horn flange. The
label is visible through the front grill on each side of the cabinet as
shown in the graphic opposite.

The HF horn can be rotated through 90°.

Tools required: Torx wrench (#TX20).

1. Undo the torx screws on the top and bottom panels of the
cabinet and remove the front grill.

2. Undo the screws holding the horn flange and rotate the horn.

3. Refit the horn as follows:
– Make sure the gasket of the horn is in place.
– Refit the horn.
– Insert all screws and carefully tighten them clockwise until

they fit precisely into the countersunk holes.

4. Refit the front grill.
