Warning

To prevent risk of fire or electric shock, do not expose any of the components to rain or moisture.
If liquids are spilled on the amplifier panel, stop using immediately, allow unit to dry out and have
checked by qualified personnel before further use. Avoid impact or dropping of the cabinets.

No user serviceable parts inside – Do not open the case – refer all servicing to qualified service
personnel.

Safety

 Ensure all fixings are secure and adequate for supporting the weight of the CLA-1460
 Ensure that the power cord is in good condition and adequate for the power rating
 Check for correct mains voltage and condition of IEC lead before connecting to power outlet
 Ensure speaker link leads are good condition with no short connections or damaged plugs
 Connect no more than 4 mid-top array cabinets to one active sub unit
 Avoid constant overload of the unit (indicated by constant lighting of the PEAK LED)
 Do not allow any foreign objects to enter the case or through the speaker grilles
 In case of failure of the CLA-1460, disconnect from the mains and check fuse. If fault repeats,

refer to qualified service personnel

Placement

 Keep amplifier panel out of direct sunlight and away from heat sources
 Avoid damp or dusty environments
 Ensure that the CLA-1460 is not positioned in a manner that may cause injury
 Ensure adequate access to controls and connections

Cleaning

 Use a soft cloth with a neutral detergent to clean the casing as required
 Use a vacuum cleaner to clear ventilation grilles of any dust or debris build-ups

Introduction

Thank you for choosing the Citronic CLA-1460 active line array system. This self-contained unit can
operate independently or as part of a larger system to provide accurate, full-range sound
reproduction for applications as diverse as theatre, conference, live music venues and houses of
worship. Please read and follow the instructions in this manual to achieve the best results and avoid
damage through incorrect usage.

Description

The CLA-1460 is a self-contained active speaker system which combines an active 2 x 12” subwoofer
with a group of 4 arrayed mid-top cabinets. The power amplifier section is housed in the subwoofer
unit which, in turn, is linked to power the 4 mid-top cabinets. Each mid-top cabinet houses a pair of
6” low-mid drivers, single 6” high-mid driver and a precision ribbon tweeter for high frequencies and
is engineered to provide a focused vertical output with a very wide dispersion for maximum
horizontal coverage

The input signal is fed via a digitally controlled EQ and dynamics processor to maximize efficiency in
the system and enable frequency adjustment to tailor the output to suit the venue or application.
Connection to a PC gives access to the DSP processor using the supplied software CDROM, allowing
bespoke programming of the response and tone characteristics of the sub and array.

Various installation methods are possible with the custom-designed mounting/flying frame,
depending upon the building or surroundings and can be combined to provide modular arrays or
multi-point sound reinforcement for larger areas.

Components

Due to the size of the components, the CLA-1460 is supplied in 6 individual cartons
Please check that you have all 6 cartons and check the contents when opening the packaging.
If any components are missing or damaged, contact your dealer immediately.
The package should contain...

 Cartons 1, 2, 3, and 4 are passive line-array mid-top cabinets
 Carton 5 is the active subwoofer unit
 Carton 6 is the mounting/flying frame

Also included should be the following

 Packet of fixing hardware
 PC Software CDROM
 Mains lead
 RS-232 cable
 USB cable
 4 x Speaker link leads

Assembly

The CLA-1460 may be assembled as a single vertically flown array, inverted as a floor-standing stack
or combined into a multiple array. Assembly for standard flown orientation is shown below.

1. Secure the 4 U-rings to the flying frame. Each must be securely fixed using the appropriate

hardware to ensure that there is no movement of the fixing or possibility of becoming unfastened
through movement or vibration and should be suspended from a permanent fixing in the ceiling
which is adequate for holding the weight of the complete line-array.

2. Securely attach the flying frame to the upper sub by connecting the M8 locknuts through the sub

pulling plate at the front edge and connecting the array bracket on top of the sub to the central
brace of the flying frame.

3. To connect an array cabinet underneath the sub cabinet, detach the ball-catch bolt from the

front pulling plate and align with the bottom of the sub pulling plate on each side and replace the
bolt through both.

4. Connect the Passive-Active Link bracket from the bottom of the sub cabinet to the rear of the

topmost array cabinet.

5. Connect further array brackets below via the front pulling plates and connect at the rear with

rear angle adjustment brackets (Angle adjustment is explained in the “Installation” section)

6. Assemble the array as shown below

Installation

Single Flown Array

For standard single flown array, installation is executed using 4 eyebolts attached to each corner of
the flying frame. Fixings should be the strongest possible type for the substrate or ceiling supports to
ensure a fail-safe installation. Suspension via wire rope or steel cables, each with a breaking strain of
no less than 400kg is recommended per single line-array system.
In some situations, it may be easier to suspend the sub unit first and then assemble line-array
speakers below it, ensuring that the weight of each is adequately supported before securing to the
array.

Once assembled, the line-array can be curved to address the listening field by selecting various angle
points on the rear angle adjustment brackets provided. The angle chosen depends largely upon the
distance from the audience and the acoustic environment but should be adjusted so that each array
speaker unit is vertically focused to evenly distribute the output across the listening field.

Each Passive Back Link bracket has numbered lines for tilt in degrees. Whilst supporting the weight
of the passive speaker, use these lines to align the correct fastening hole for the degree of tilt
required for each component in the array.

Multiple Flown Array

For multiple flown line-array, installation is similar to that
of a single array with sub cabinets coupled together and
passive units all flown in a single, longer array.

With the uppermost sub unit attached to its flying frame,
secure the 4 eyebolts for flying the array.

Subsequent sub units can be attached underneath
the topmost sub cabinet by connecting together the front
pulling plates and the upper and lower array brackets.

Connection of passive units from the bottom sub unit is
executed in the same way as for a single line array, with
each group of 4 passive units linked in a single line-array.

Split Array

The flying frame can also mount directly to the mid-top array cabinets via the front edge pulling
plates and connecting the Passive – Active link directly from the rear of the topmost array speaker to
the centre brace of the flying frame. Sub units can then be floor-standing and linked to 4 array
cabinets each with longer cables

Floor-standing Stack

Where flying or ceiling mounting is not possible, it may
be useful to arrange the CLA-1460 as a free-standing
stack on the floor or on a stage. In this orientation, the
sub unit sits on its flying frame on the floor and the
passive units are splayed upwards above the sub unit.

Prior to assembly, do not attach the 4 eyebolts to the
flying frame. If the frame is likely to damage the floor
surface, protect with rubber or other scratch-resistant
material, or it may be preferred to mount the frame on
castors for portability.

Assemble passive units above the sub in the same
manner as for a standard flown array shown above but
inverted. Splayed angle adjustment may be used for
venues with raised rear seating areas (e.g. theatres)
