Description

The world’s first, network-controlled Digi-Loop induction loop amplifier from Williams Sound now features control via Crestron®. This next-generation Digi-Loop continues to offer DSP audio processing with flexible, powerful software control of mixing, equalization, compression, loop phase shift and more. Its potent Class D, pulse-width amplifiers maximize efficiency, and reduce size and weight. Digi-Loop’s dual-amplifier design offers impressive flexibility, with the option of a single 12A output for large perimeter loops, or dual 10A outputs for phase loop arrays. With its ability to power a loop and a speaker, Digi-Loop shines as a complete room solution.

Specifications

PLA DL210 NET Architectural and Engineering Specifications

The loop amplifier shall be designed for rooms of up to 6500 sq. ft. (600 sq. m) with loop signals and is the ideal solution for events and meeting venues.
It shall have one XLR digital audio input for use with digital audio sources such as pro audio consoles with digital AES/EBU output, etc. It shall have an ethernet jack for Dante digital audio input.
It shall have an ethernet jack to provide configuration capability over an ethernet (10 base T) network.  It shall have an additional ethernet jack for connection to a Dante network.
It shall have an RS-232 jack to provide control capability from 3rd-party controllers such as Crestron, AMX, Extron, etc.
It shall have a USB jack to provide access to internal configuration with a computer.
It shall have two MIC/LINE LEVEL inputs that can be configured as LINE (balanced) or as MICROPHONE input(s).  These inputs shall be mixed with the RCA LINE inputs into one mono output for the loop.
It shall have two RCA LINE inputs that can be used to supply one or two channels of audio.  These two channels shall be mixed together, then mixed with the two MIC/LINE inputs into one mono output for the loop.
It shall have a 70-100V input to provide a speaker-level input connection for use with distributed speaker systems.
It shall have two LINE OUTPUTS to provide loop-through connections for line level signals going to other equipment such as recording devices.  These line outputs shall be the summed combination of the MIC/LINE LEVEL inputs and the RCA LINE inputs.
It shall have two LOOP OUTPUTS for running either one large loop, two individual loops, a phased-array system, or 1 loop + 1 speaker.  Output A will be configurable in the menu to be a speaker output.
It shall have a 1/4" Headphone jack for monitoring.
It shall provide an output of up to 12A rms on output A, for one loop with optimum loop field strength. When both outputs A and B are used, each output will supply up to 10A rms.
It shall be compatible with either US or international power systems with the appropriate power cord.
The loop amplifier with the ethernet jack shall be the Williams Sound model PLA DL 210 NET.
The loop amplifier with the ethernet jack and Dante jack shall be the Williams Sound model PLA DL 210 NET D.
