Description
The Di Series of installation system amplifiers offer a unique combination of high power and audio performance, seamlessly combined with advanced DSP and network control. The Di Series offers three models, physically identical eight-in-eight-out amplifiers but with varying total output power configurations of 6,000 watts (Di06), 10,000 watts (Di10) and 20,000 watts (Di20) to suit specific loudspeaker models and audio applications. The Di Series models offer extremely high power density in a convenient and flexible forma, primarily intended for installation but equally suited to mobile applications where high channel density is required.
Di Series installation system amplifiers represent an ideal solution for powering EM Acoustics loudspeakers. Each amplifier comes loaded with preset files for all EM Acoustics loudspeaker products, as well as a dedicated “linear” preset with no processor settings applied – but also blank memory slots for users to create their own setting files. Aside from the non-adjustable factory settings for each EM Acoustics product, users have access to a variety of processing functions including gain, delay and EQ (parametric and shelf) for system or venue optimisation. Power delivery is an area where the Di Series amplifiers are unmatched. A state-of-the-art switchmode power supply with power factor correction ensures that a Di Series amplifier can deliver all that is required, even under demanding load conditions and across a wide range of mains supply voltages. Di06 and Di10 amplifiers feature an automatic load sensing function which allows them to deliver maximum power into higher impedances. This makes them very cost effective and flexible in a variety of applications. The use of state-of-the-art components and a finely optimised design results in generous power reserves, thus ensuring that pristine sound quality is maintained even under the most extreme conditions, anywhere in the world.
Di Series amplifiers have both analog inputs (8) and AES3 digital inputs (2) as standard, and can be supplied with an optional Dante™ networked audio input card if required (model numbers Di06D, Di10D and Di20D). Maximum flexibility was the thought process with regards the input infrastructure – the eight-in-eight-out configuration allows the Di Series models to be highly flexible whether deployed powering front of house systems, monitor mixes, or fill loudspeakers.
The front panel has been designed to give reassurance in installation applications that settings will not be adjusted accidentally – and as such presents no control options of any kind. LED indicators give input signal level, mute and clip status, and a second set of indicators are provided for output level and limiter status. Additional indicators give further status for the amplifier including communication status, amplifier sleep and Dantetm status.
Di Series amplifiers are built around a 2U all-metal chassis to ensure a lifetime of reliable performance. Low-noise variable speed fans are fitted, along with a reticulated foam dust filter which can easily be removed for cleaning. The rear panel houses the all connections – analog input connectors and AES3 input and link connectors are provided on 6-way Phoenix connectors. The primary network communications port is provided on RJ45, and additional Phoenix connectors are provided for RS485 & RS232 communications, as well as auxiliary ports and contact-closure input and relay output connections. Output connections are provided on Neutrik speakON™ NL4. Mains power is connected via a 32A Neutrik powerCON™ locking type connector. If fitted, the Dante™ primary and secondary RJ45 ports are also located on the rear panel of the amplifier.
The Di Series represents a huge leap forwards In amplifier technology, and offers users significant ease of use, improved reliability and better return on investment compared to traditional amplifier/processor combinations.
