It fulfills the user’s needs and expectations by far. SNIFFER is not only visualizing the various commissioning procedures but also provide streamlined methods for faultfinding and device allocating without the direct need for a digital communication protocol over the 2-wire audio line’s. Front buttons and indicators allow for quick access to the various functions and indications of the Loopdrive system. The LDB clicks on a DIN-rail that provides DC-power and accommodate for the RS485 data connection and GeneralFault contact to a maximum of 32- LDB ’s on a single DIN-rail. Audio transformers or audio signal isolators are another way, but good quality ones cost real money. One amplifier channel can be split into multiple LDB in parallel, creating multi-loop with individual surveillance for multi-zone paging applications. A single LDB can pass 800 W of audio signal from an amplifier and injects at the same time DC to the loop for powering and managing FIM modules. 5.3. Pin 2 Impedance: >5000 Ohms Max Level: +2 dBu Distortion: <0.2 THD (.
#AUDIO ISOLATOR CIRCUIT PROFESSIONAL#
The input circuits of a professional audio device should of course be.
This device drives up to 200 FIM ’s over a dual-core cable. The MT-701 can also be used to bridge two Encore Partyline systems together. GS-ET2 Two Channel Audio Isolation Using High Specification Lundahl Transformers. T he L oop D rive B ooster ( LDB ) is the heart of the Loopdrive system. The simplest and most common way to do the isolation is use audio transformer.
