CXV225NA & CXV425NA User Manual v1.04

General Description

The Cloud CXV225NA and CXV425NA are high power

(250 W/ch), multi-channel audio ampliers intended for use
with high quality PA and background music systems in ofces,

hotels, factories, leisure facilities and other commercial and
industrial premises.

They are designed to drive 70 V-line speaker systems directly,
and have no low-impedance outputs. Low impedance

loudspeakers can only be connected to these ampliers

with the use of an intermediate 70 V-line transformer.
Loudspeakers designed for such ‘installed-sound’ applications
will normally include an integral transformer, typically with
selectable output power taps. If you have any doubt about

the suitability of this amplier for the speaker system it is to

be connected to, please verify that the speakers are of the
70 V-line type with the manufacturer.

Unlike traditional 70 V-line amplier designs, the CXV225NA

and CXV425NA do not employ an output transformer. This

produces a considerable saving in weight and a signicant

improvement in audio quality.

Applicable Models

This manual describes the installation and operation of the
following models:

• Cloud CXV225NA 2-channel amplier –

2 x 250 W, 2U 19” rack unit

• Cloud CXV425NA 4-channel amplier –

4 x 250 W, 3U 19” rack unit

Apart from the number of channels and the units’ physical

dimensions and power consumption gures, the two

models are otherwise identical for the practical purposes of
installation and operation.

Installation

Mechanical

The ampliers are designed to be mounted in a standard 19”
equipment rack. The front panels are tted with rackmount

ears for this purpose. The CXV225NA requires 2U of
vertical rack space, the CXV425NA requires 3U. See notes
below regarding spacing and ventilation.

Due to the units’ weight, the use of additional side supports
is recommended.

Ventilation

The CXV425NA is force cooled by two thermostatically­controlled fans mounted on the rear panel. The fan is
operative at all times, remaining at low speed at internal
temperatures below 50°C, then increasing in speed above
this temperature to a maximum speed at 70°C.

The CXV225NA has a single fan mounted internally to keep
noise to a minimum.

Always allow adequate space around the amplier(s) to
allow a free ow of air through the unit(s). Ensure that cable

bundles or other items do not obstruct any grilles.

In 19” rack applications we recommend leaving 1U of rack
space above and below each unit. Plain 1U blank panels,
not slotted ventilation panels should be used, as the latter
reduce the effect of forced-air cooling. The direction of

airow is from front-to-rear (CXV425NA) and front-to-

sides (CXV225NA); it is recommended not to mix these

ampliers with other equipment employing forced-air

cooling which acts in the opposite direction within the same
rack.

Sensitivity and Gain Control

Control of input level is provided by a preset rotary
control adjacent to each input connector. The control
should be adjusted using a trim tool or small screwdriver.

Full attenuation of the input signal – i.e., zero output – is

obtained with the control fully anti-clockwise. Maximum
sensitivity is with the control fully clockwise; at this setting
the maximum output level of 70 V
input signal level of 0.775 V

rms

will be produced for an

rms

(0 dBu).

We recommend that the level for each channel should
be adjusted after installation is complete to ensure that
adequate, but not excessive sound levels are achieved with
the programme material that will be used in practice.

Input Routing

To facilitate the use of the ampliers in multi-zone

applications, input selection switches are provided on all
channels except Ch1. This gives the installer an easy method
of paralleling channels from a single input.

Inputs

Each amplier channel has an electronically-balanced input

on a 3-pin 3.5 mm-pitch screw terminal connector. Twin­core screened cable should be used when driving the

amplier inputs from a device with a balanced output. Single-

core screened cable can be used when connecting to an
unbalanced source.

Remote Control of Level

The CXV225NA and CXV425NA ampliers are compatible

with standard Cloud remote control plates type RL-1 Series,
allowing control of level from a remote position. In order

to use the ampliers with the RL-1, VCA cards must rst be
tted in the channels to be controlled remotely. See page 10
for details of VCA cards and tting. Once VCA cards have
been tted, RL-1s may be connected at the rear 3-pin 5 mm-

pitch screw terminal connectors (Remote Level), using the
wiring shown below.

Outputs

The 70 V-line speaker output terminals are behind the
removable output terminal cover (see page 7). The covers

are tted with a cable gland (one per channel); to use these,

slacken the rear nut by a few turns and feed the cable
through. The plug-in connectors are suitable for cable cores
up to 2.5 mm2.

g.7: Remote level control wiring

Use two-core screened cable to connect the remote level
plate (maximum length 100 metres).

Caution: The amplier should never be operated without

the output terminal cover installed. Apart from exposing
the high voltage terminals, leaving the cover off also

compromises the amplier’s forced-air cooling.

The amplier’s transformerless output stage is designed

to drive up to 70 V

into an impedance of at least

rms

20 ohms (each channel). Check the input impedance of the

loudspeaker type in use and divide this gure by the number

of loudspeakers* to ensure that the total impedance is
greater than 20 ohms. Alternatively, add the wattages of all
the loudspeakers being driven by each channel (taking power
tappings into account); the total must be less than 250 W.

* Assumes all loudspeakers in the system are of the same type and have the
same tap setting.

CXV225NA & CXV425NA User Manual v1.0 9

Protection

The ampliers include comprehensive protection circuitry

to prevent damage to loudspeakers, the output devices and
other components in the event of a fault condition.

speaker processor) or when the speaker manufacturer
explicitly states that they will operate correctly at such low
frequencies.

For speech-only

Thermal Protection

The output device heatsink temperatures are monitored and
the protection circuitry activated if any should exceed 90°C.
The red front panel PROTECT LED for the appropriate
channel illuminates to indicate the fault condition.

DC Protection

Crowbar protection is provided to safeguard the
loudspeakers in the event of DC being present at the output
terminals. This is an emergency protection feature that

will only operate in the event of the amplier developing a

fault. Its action is liable to blow internal DC rail fuses. The

amplier must be serviced before any attempt is made to

use it further.

Short-circuit protection

VI limiting is implemented in the ampliers to protect the

output stages from excessive dissipation caused by abnormal
loads; for example, a short-circuit.

Switch-on protection

Settings somewhere between 100 Hz (12 o’clock) and

200 Hz are appropriate. Start with the lter set to 100 Hz

and turn the control clockwise whilst listening to speech
through the system until you can hear a loss of bass in the
voice. Few voices contain any useful signal below 200 Hz,

so in many cases the lter can be set to 200 Hz without

any real loss of quality. Often a setting this high will actually
enhance the clarity of the speech, reduce microphone
handling noise and reduce breath blasts.

For music systems

The optimum lter setting will depend on the speakers

and their transformers. It should be recognised that many
70 V-line speakers have inferior LF performance compared to
low impedance speakers. If the manufacturer recommends

a minimum frequency of operation, set the lter to this.

Otherwise, settings between 70 Hz and 100 Hz should be
appropriate.

Test the system at full volume with a variety of music
containing high level, low bass notes and listen for any
distortion. If the transformers saturate, distortion will be
clearly audible. In this case, turn the control clockwise until
it disappears.

The protection circuitry is also activated immediately after

the amplier is switched on. This is to prevent any voltage

spikes due to start-up conditions from damaging the
loudspeakers. The protection circuitry automatically times
out after approx. 5 seconds. All PROTECT LEDs illuminate at
switch-on for the duration of the time-out period.

High Pass Filters

Most transformers tted to 70 V-line speakers exhibit

core saturation when fed with high-level signals at low
frequencies. Transformer saturation creates unpleasant
distortion and stresses the system. To counteract this, a

correctly congured high pass lter is an essential part of

any 70 V-line system. The CXV225NA and CXV425NA have

variable frequency high pass lters in each channel, accessible

at the rear panel (see page 7). These should be adjusted to
reject low frequencies, to suit both the speakers and the
application. When adjusting, bear in mind that the higher
the frequency setting, the less likely it is that the system will
suffer from saturation problems.

The minimum (20 Hz) setting should only be used when

the system has some other form of lter or protection

from high-level low frequency signals (e.g., a dedicated

VCA Cards (optional)

Cloud VCA-5 modules must be tted to the CXV225NA
and CXV425NA ampliers if remote control of audio level

is required. One VCA-5 module is required for each channel,

and as many as necessary may be tted. The VCA modules

use the industry-standard That’s 2181 VCA device, which
provides very low distortion and up to 90 dB attenuation at
cut-off.

The VCA module can also be used to provide muting by

using an auxiliary relay connected to a re alarm control

panel. Please contact our technical department for further
details.

Installation

• With the power turned off and the mains cable

removed, remove the top panel.

• Refer to the pcb layout diagrams on page 13. Locate the

VCA connector for the rst channel being tted, and

remove the jumper joining one pair of pins.

• Unscrew the blanking plate from the rear panel.

CXV225NA & CXV425NA User Manual v1.010

• Remove and retain the M3 xing screw adjacent to the

connector, and t the 35mm M3 hex spacer supplied

with the VCA-5 in its place.

• Push the 10-way VCA plug onto the PCB connector,

aligned so the cable enters it from the rear of the
chassis. Check there is contact with all 10 pins.

• Locate the VCA module’s 3-pin socket in the rear panel

cut-out and secure using the M3 screw provided.

• Replace the top panel.

Once the VCA-5 modules have been installed, RL-1 remote
level control plate(s) may be connected to the REMOTE
LEVEL connector(s) on the rear panel.

General Notes

EMC Considerations

CXV Series ampliers have been designed with a range

of electromagnetic compatibility (EMC) measures and so
are technically well behaved. You should experience no
problems interfacing units to other items of equipment and
under normal circumstances, no special precautions need
to be taken. If the unit is to be used in close proximity to
potential sources of HF disturbance such as high power
communication transmitters, radar stations and the like, it is
suggested that input signal leads be kept as short as possible.
Always use balanced interconnections wherever possible.

Loudspeaker Equalisation Modules
(optional)

The CXV225NA and CXV425NA may be optimised for
use with certain popular installation speakers from various
manuafcturers; a single-channel equalisation module may be

tted to as many channels as necessary. Equalisation modules

for the following loudspeakers are available:

Bose®

• Panaray® MA12

• Panaray® 402-II, 502B and 502BEX

• Panaray® LT Series: Models 3302, 4402, 9402 and 9702

• Freespace® DS 16 range

• Freespace® Model 16

• Freespace® Model 32 range

Amina

• AIWX Series

• LFiT Series

Other modules are available; please enquire.

Installation

• With the power turned off and the mains cable

removed, remove the top panel.

• Refer to the pcb layout diagrams on page 13. The

modules plug into the white 12-pin connectors on the
PCB. Note the header connectors on the PCB have two
notches on one side only; these engage with lugs on
the equalisation module’s mating connector to ensure
correct orientation.

Earthing

When several mains powered units are connected together
via their signal cables, there is a risk of one or more earth
loops which may cause an audible hum on the system even
with the gain controls set to minimum.

The 0 V rail of a CXV Series amplier is directly coupled to

the chassis ground. No interconnection problems should be
encountered, but if there is any hum or other extraneous
noise when source equipment is connected, the situation can
generally be remedied by observing the following guidelines:

• Always connect sources using balanced connections

wherever possible, with the cable screen only connected

at the receiving end (amplier input).

• Use audio isolating transformers (readily available from

trade suppliers) at the inputs if necessary. These will

ensure that the amplier is electrically isolated from the

source equipment.

• The signal source units should be located as close as

possible to the ampliers and the metal housing of

the various units should not be electrically connected
together through the equipment rack. If this is a
problem, rack isolating kits are available from specialist
hardware suppliers. If the problem persists, try to
connect all interconnected units, including power

ampliers, to a common power source to ensure a

common ground is provided.

• After tting equalisation modules to any channel(s),

the corresponding module bypass jumper(s) must be
removed in order for the module to function. Refer to
the pcb layout diagrams for jumper locations.

• Replace the top cover with the original screws after

tting.
