SA750 er en tilbagevenden til de tidlige JBL-modtagere. Men med et moderne ravgult LED-display, exceptionelt dynamikområde og tilslutningsmuligheder er SA750 en moderne klassiker med rødder i nutidens bedste teknologier. Den er designet til at supplere JBL Classic- og Studio Monitor-højttalerne. Med JBL SA750 kan du afspille din yndlingsmusik via Chromecast built-in, Apple AirPlay2, Roon eller Harman MusicLife-appen. Den indeholder DIRAC Live til at finjustere lyden fra dine højttalere i lytterummet. En højtydende højopløsnings-DAC sikrer enestående ydeevne hver gang. Klasse G-forstærkning bruger flere strømforsyninger til at levere de første 20 W pr. kanal uden forvrængning. Forstærkeren kan levere en kontinuerlig effekt på 120 W pr. kanal for vedvarende dynamisk musik. Med otte digitale og analoge indgange, herunder MM/MC-phono-indgange, er SA750 klar til enhver lydkilde.

SA750 Software Revival Guide

Reason	Revival method for SA750 if a problem exists after a stalled software update
Symptoms	Unit will display “NET UPDATING” on the front panel display and will not complete startup
Parts required	1) a USB stick, 2) a computer for transferring files to the USB stick, 3) unit software detailed in this guide

Download the software bundle by clicking here . You will download a zipped folder called “SA750 v1542 Reflash Bundle.zip”
Unzip/extract this folder (some computers will do this automatically). Inside the folder you will find 2 more folders named “Step 1 V1206 V1.72” and “Step 2 V1542 V1.72”
Double click on the “Step 1 V1206 V1.72” folder. Inside you will find a file named “image.swu”
Copy this image.swu file to a blank USB memory stick.
- NOTE! The file MUST be called image.swu. If you copy the file to a location where there is already a file called image.swu your computer may rename the file automatically (for instance as “image.swu (1)”. Please double check that the file is called “image.swu” when on the memory stick.
Power off the SA750 from the hard power switch on the rear of the unit immediately above the mains inlet socket.
Insert the USB memory stick into the rear of the unit.
Depress the recessed service switch (above the CD input connector sockets) and continue to keep it depressed.
