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)
Connection
Using the supplied speaker leads, connect 4 passive units to one sub unit as shown below. For multiple arrays, connect each group of 4 passive units to one sub unit. No more than 4 passive units may be connected to a single sub. Use the supplied IEC lead to connect to mains, ensuring correct voltage and power capacity Connect signal input via XLR (connect to LINE input – not to be confused with RS-485 input) To continue the signal onto further units, connect from the XLR LINE output
Active Amplifier Module with DSP
The internal amplifier in the sub unit is optimized for use in conjunction with the 4 passive array speakers with built-in stepless variable fan cooling, overload protection and short-circuit protection. The rear panel features a power switch and single rotary volume control with PEAK LED. If this LED lights more than momentarily, the amplifier is liable to clip and the volume control should be reduced until the PEAK LED lights only for an instant each time.
Input signal is processed via a DSP circuit for dynamics and EQ control, helping to protect the system and tailor the tonal response to the venue or particular application. A CDROM is included containing PC editing software for the CLA-1460 processor section. Connection to a PC can be made using USB, RS-232 or RS-485). See “Software Application Guide” for further information.
