LD Systems DS21 19″ DSP Controller 3-channel

The LD DS2.1 is a universal 3-channel DSP controller for 2.1 loudspeaker systems with 24-bit processing and convenient front panel operation providing easy setup and high quality audio performance.

Designed for live sound and fixed applications the rack mountable unit offers extensive parameter control of its EQ, crossover, delay and limiter functions. The LD DS2.1 features a 3-band parametric EQ with adjustable Q and high shelf / low shelf selection. The crossover includes Butterworth, Bessel and Linkwitz-Riley filters with 6 dB to 24 dB slopes. Delay time is adjustable to a maximum of 12.5 ms for each of the three outputs and the limiter provides independent threshold and hold time setting for the L / R and subwoofer channels.

A backlit 2 x 16 LCD and jog wheel allow for quick parameter adjustment and recall of up to 6 presets. Also provides real time level meter. The rear panel features XLR connectors for left and right input, left and right plus sub XLR outputs and a USB port. Software and a power cord is included.

With the DSP 260 digital 2-in-6 sound system manager, DYNACORD is continuing its proud tradition in the fi eld of innovative digital signal processors.
Based on the most modern hardware, this system manager offers tried-and-tested as well as new algorithms for the simple and swift construction of active multi-way systems. As much importance has been attached here by the developers to high user-friendliness as to the realization of an extremely favorable price.
24-bit sigma-delta AD/DA converters and a 32-bit floating-point signal processor make possible a dynamic range of 111 dB. In addition to the two analog inputs, a digital stereo input in AES/EBU format is available. A -6 dB pad switch in front of the AD converters offers additional security against overload when the device is connected to mixing desks with very high output levels. The 6 individually mutable outputs are electronically balanced and available on XLR sockets. For all inputs and outputs, easily read LED level meters are provided on the front panel.
Users can choose whether to configure their own systems at the device itself using the controls and display provided or else by means of the intuitive editing software.
3-way stereo, 2-way stereo + FR, 4-way mono + FR etc. Furthermore, factory presets compatible with those of the tried-and-tested DSP-244 are available for Dynacord loudspeaker systems.
In terms of DSP, the device offers parametric and graphic EQs as well as a delay function in the input and crossover, channel EQ, channel delay and a level control with limiter in each output channel.
An RS-232 interface allows Master/Slave operation of multiple devices as well as GPI switching of settings. A PC (the editing software runs under Windows) can be connected via the USB interface on the front panel.
A variable parameter lockout function allows you to determine which settings and parameters can be accessed directly at the device. This is just one of many features that make the DSP 260 an ideal choice also for the rental business.
The wealth of features combined with its outstanding audio performance and favorable price commend this audio system manager for a multitude of professional applications.

Full-featured Speaker Processing in a 1U Space
Speaker processing can be a complicated business requiring a substantial array of equipment, but the Yamaha SP2060 offers everything you need in a single rack space. This innovative 24-bit, 96-kHz digital speaker processor delivers excellent sound quality, an impressive variety of processing functions — gain, delay, PEQ, comp, crossover, limiter, and an all-pass filter for phase adjustment — and intuitive programming from Yamaha's DME Designer application running on a personal computer. It has two analog inputs and six analog outputs, plus two AES/EBU format digital inputs for connectivity with a broad range of systems. And if you use Yamaha Installation Series Speakers, all you need to do is select one of the many optimized presets provided for great sound with minimum measurement and setup time. The SP2060 is a compact, portable 1U unit that is ideal for live sound or installations.

Based on a two-in, six-out topology, the DC-One is designed primarily for users of small-to-medium sized sound systems in both mobile and installed applications. While the unit is an all-new development based on a powerful SHARC processor, it is 100 percent compatible with all settings from other Electro-Voice signal processors. A large part of DC-Oneʼs development was aimed at ensuring that users can easily handle its serious digital horsepower and high-end audio performance. Free. PC-Editor software is available, or the DC-One can be operated via the front panel.   A/D Conversion    24-Bit Delta-Sigma
