Product Overview

The CS7 is an ultra-compact, powered, intelligent, line array enclosure designed for medium throw applications. It contains two symmetrically arrayed 7" LF transducers, and a 3" HF compression driver mounted onto an Adamson waveguide. The high frequency waveguide is designed to couple multiple cabinets across the entire intended frequency band without loss of coherence.

Each CS7 cabinet houses proprietary Class-D Amplification and comprehensive internal signal processing including Milan AVB connectivity. Internal switch fabric allows multiple enclosures to be daisy-chained in order to reduce the required amount of cabling in complex system setups.

The operational frequency range of the CS7 is 80Hz to 18kHz. The use of proprietary technologies such as Controlled Summation Technology and Advanced Cone Architecture allows high maximum SPL and maintains a consistent nominal horizontal dispersion pattern of 100° down to 400Hz.

The enclosure is made of marine grade birch plywood, with an integrated aluminum and steel four-point rigging system. Without sacrificing low resonance to composite material, the CS7 weighs only 17.5 kg / 38.6 lbs.

Up to sixteen CS7 can be flown in the same array when using the Ultra-Compact Support Frame (930-0025) and up to eight when using the Ultra-Compact Micro Frame (930-0027). Nine rigging positions are available, allowing vertical inter-cabinet splay angles from 0° to 12.5°. Always consult Adamson's ArrayIntelligence software and the CS-Series Line Array Rigging Manual for correct rigging positions and proper rigging instructions.

The CS7 is intended to be used as a standalone system or with other CS-Series products and is designed to pair easily and coherently with all CS-Series subwoofers.

Power

The CS7 utilizes advanced loudspeaker technology, augmented with advanced power processing. Understanding electrical safety is critical in the safe operation of this product.

This product must always be grounded/earthed. Do not ground-lift the AC cable - never use a ground-lifting adapter or cut the AC cable ground pin.

Improper grounding of connections between loudspeakers and the rest of the audio system may produce noise or hum and can damage the input and output stages of the system's electronics components.

Before applying AC power to the loudspeaker, make sure that the voltage potential difference between the neutral and earth/ground lines is less than 5 VAC when using single-phase AC wiring.

The CS7 is equipped with one Neutrik powerCON™ TRUE1 TOP 16 A locking input connector and one Neutrik powerCON™ TRUE1 TOP 16 A locking output connector on the CS7.

The accepted voltage range is 100 V - 240 VAC.

The CS7 is protected against excessive line voltage spikes but will need to be serviced should that protection be engaged long-term in an overvoltage condition, resulting in the fuse link breaking.

The input voltage supplied to the AC Input connector will be the same voltage supplied to any additional CS-Series products connected to the CS7's AC Output connector. The number of loudspeakers that is safe to link in this manner is determined by the supply voltage, the total current draw of all connected loudspeakers on the circuit, the circuit breaker rating, and the rating of the utilized AC cabling.

When linking AC power for additional CS-Series products, do not exceed the current capability of the AC Input connector. Consider the total current draw for all loudspeakers on the circuit, including the first.

For long periods of idle it is recommended to switch amplifiers to standby (requires Adamson's ArrayIntelligence software) to reduce cooling fan run-time.

Table 1 - Single Cabinet Current Draw (A)

Current draw for the CS7 is dynamic and fluctuates as operating levels change.

The Power Distribution Sysytem (PDS, 914-0002 - 110 V/914-0003 - 230 V) provides six individually protected AC circuits of 208/230 V, 16 A. When using the Adamson PDS, you can link a maximum of six CS7 loudspeakers per circuit.

When wiring an AC cable for use with this product in a single-line system, use the wiring scheme described below in Table 2 and illustrated with Fig. 1. All work must be completed by a qualified technician.

Connectivity

On-board Digital Signal Processing (DSP) is accessed via two data ports on the rear of the cabinet. These ports are used to stream AVB audio as well as transmit AES70 control data. All CS-Series loudspeakers are configured to receive two separate LAN signals on a single data link. The Network Distribution System (NDS, 905-0039) combines both LANs on one Ethernet cable. This approach allows network redundancy as well as the ability to daisy-chain control data and digital audio between enclosures.

When using the NDS, up to six CS-Series loudspeakers can be daisy-chained on a single network path. This quantity takes into account the Gateway, the NDS, the network switches, as well as each CS-Series loudspeaker to determine the amount of latency created by each individual hop, and ensuring the total latency remains within pre-determined parameters. The audio signal latency between each CS7 is 0.26 ms, jump to jump.

All CS-Series cabinets are Milan-certified. With Milan, every device will automatically connect with any other Milan device using a variety of standard formats and definitions in the protocol.

Each CS-Series loudspeaker is equipped with balanced XLR input and output connectors for line level analog audio signals.

The CS7's drivers are powered by a proprietary two-channel class D amplifier capable of providing up to 2400 W of combined output power.

Rack Mounted Systems

Gateway (913-0003) - The AVB on-ramp into the CS-Series ecosystem, the Gateway is a 16x16 matrix with 16 channels of user accessible DSP, containing dual-LAN, Milan AVB, AES/EBU, and analog connections. The Gateway converts AVB to and from analog and AES/EBU. An extremely powerful tool, the Gateway's network connectivity also allows for integrating other systems link broadcast feeds or matrixing multiple consoles in a festival environment.

Bridge (913-0005) - The Bridge is designed to replace existing network infrastructure in Adamson's E-Rack, allowing users to seamlessly integrate CS-Series loudspeakers into their existing inventories by converting dual- LAN, Milan AVB signal to AES/EBU for networking to existing Lab Gruppen amplifiers, while also offering six channels of DSP per unit.

Network Distribution System NDS (905-0039) - The NDS is a network and analog patch bay that allows users to send redundant audio and control to CS-Series loudspeakers on a single network cable. The NDS combines LAN A and B network ports using two external AVB enabled switches.

Power Distribution System PDS (914-0002/914-0003) - Available in 110 V (2x L21-30) and 230 V (32 A CEE) models, the PDS is designed to ensure that all components of the CS-Series ecosystem receive ample power. The PDS provides six circuits of 208 V or 230 V, 16 A offered via powerCON or Socapex outputs. An integrated data port allows users to monitor consumption data via ArrayIntelligence, both per power output and for overall draw.

ArrayIntelligence

ArrayIntelligence is a single software platform which allows the user to design and deploy a system, all from a single interface. From room design and simulation to connectivity and diagnostics, this unified platform reduces the need for additional software in order to properly deploy and deliver complete audio systems.

Blueprint - Design your space using basic geometric shapes. Users can create any environment from a basic field, to a complex structure. When arena or stadium design is needed, multi-point Extrude and Revolve surfaces will easily allow you to set multiple inclines and elevated surfaces with a few keystrokes.

Simulation - After placing virtual cabinets in your room design, different aspects of their behaviour may be simulated, including 2D and 3D SPL, delta time of two cabinets, and speaker directivity.

Patch - Assign virtual loudspeakers to their real-world counterparts quickly and effectively. Determine control zoning and AVB routing to ensure complete control over your environment.

Optimization - With DSP in every cabinet, you have more control than ever over your system. Adamson's proprietary Optimization algorithm gives you incredible control over the listening experience, taking advantage of each line array element's on-board DSP to deliver accurate, uniform sound.

Control - Gain, Muting, Delay, EQ, and Grouping are all controlled on a single page, allowing you to build and fine-tune your system with as little friction as possible. Implement your changes on a per-box level or use control zones to shape the performance of multiple cabinet groupings.

Metering - Access input and output metering for all online devices on one page, so you can reliably determine headroom for your entire system.

Diagnose - Monitor your system with a comprehensive set of system insight tools including spectral impedance and displacement, inclinometer monitoring, clip and limiter tracking, power consumption, and AVB stream statistics.
