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.

1. Safety precautions

2.1. Product description

Vi7P/Vi10P are passive 3-way loudspeakers housing two 10" LF
drivers, one horn-loaded 8" MF driver and a 1.4" HF compression
driver with a rotatable CD horn producing a nominal dispersion (h
x v) of 75° x 40° (Vi7P) or 110° x 40° (Vi10P), respectively.

All components are arranged symmetrically around the center axis
of the cabinet to produce a perfect symmetrical dispersion pattern.
This setup allows for a crossover design with a well defined
overlap of adjacent frequency bands resulting in a very consistent
and accurate vertical dispersion. Due to the dipolar arrangement
of the low drivers, broadband vertical dispersion control is
maintained down to approximately 350 Hz – an outstanding
feature for a passive 3-way system.

The frequency response extends from 59 Hz to above 18 kHz.

The cabinets are constructed from marine plywood and have an
impact and weather protected PCP (Polyurea Cabinet Protection)
finish. The fronts of the loudspeaker cabinets are protected by a
rigid metal grill backed by an acoustically transparent foam.

The cabinets are fitted with two M10 threaded inserts each on the
top, bottom and rear panels to accept either:

– the Z5383 VP Mounting bracket,
– the Z5384 VP Flying adapter,
– or the Z5384 VP Flying adapter.

In addition the Q9032 Safety eye bolt M10 can be used to apply
an independent secondary safety device.

2.2. Connections

The cabinets are fitted with a pair of NL4 M connectors and a two
pole screw terminal block (ST). All four pins of both NL4 M
connectors are wired in parallel. The cabinets use the pin
assignments 1+/1–. Pins 2+/2– are designated to active
subwoofers.

Cabinets with the weather resistant option (WR) are equipped with
a fixed input cable (PG type, H07-RN-F, 2 x 2.5 mm2 (AWG 13),
standard length 5.5 m (18 ft).

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

Fixed cable connection

The Vi7P and Vi10P loudspeakers are each supplied with a cover
plate [1] and a rubber grommet feed through [2]. For indoor
operation, these items can be used to hide the connector panel, if
required. For unprotected outdoor operation, the connector panel
must be covered, i.e. both items must be used to achieve an IP
degree of protection of IP34.

To install the fixed cable connection, proceed as follows:

Tools required: Philips screw driver (#PH2).

1. Remove the knockout opening in the cover plate [1] and
attach the rubber grommet [2] correspondingly.

2. Insert the connection cable through the rubber grommet.

3. Undo the four screws of the connector panel.

4. Connect the cable wires to the screw terminal.
Þ Observe the correct polarity!

5. Push the cover plate towards the connector panel until it fits
into place.

6. Finally fix the cover plate together with the connector panel
using all screws.

NL4 connection with cover plate

The two NL4 connector sockets of the cabinet's connector panel
are located in a recess to allow the use of the cover plate [1]
together with NL4 cable connectors, as shown in the graphic
opposite.

Note: Neutrik NL4FC type connectors must be used for this
option.

The cover plate is equipped with two knockout openings to allow
daisy chaining of the loudspeaker.
To use the NL4 connection, proceed in the same manner as
described in the previous section.

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.

Application Setup Cabinets per

channel

Vi7P V7P 2

Vi10P V10P 2

For applicable d&b amplifiers, the controller setups are available
in Dual Channel and/or Mix TOP/SUB mode. For combinations
with active subwoofers fed by a single 4-wire cable Mix TOP/SUB
mode must be selected.

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.

NL4 cable connection with cover plate [1]

d&b Vi7P/Vi10P Manual 1.1 en 7

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.
