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.
