LA890 - i require the manual

Hello :-)

Ive just aquired a LA890 and haven't a clue how to wire it correctly. Unfortunately when i bought this off eBay no manual was included or wires. So i have bought the wiring and am eager to get this set up and tested dispite the bad reviews about the amp.
I've searched the net and emailed LagacyAudio in search for a manual but am having no luck :-/

Does anyone know where, or a direct site i can download the manual from?

SOURCE: i dont know waths the amp for the two fuse on my Legacy II LA890

if you've got the LA890 it takes two 20 amp fuses. However i believe the left fuse is merely a spare; there is no connection to it inside!

Hope this helps.

SOURCE: crainemy la690 amp is mounted

You need to look at your wiring of the speakers and the Ohm rating on your speakers.
Below are the specs of the amp. You have the Tri-Way amp and the switch that controls
which way it configures it's output is critical. If you are powering just 2 speakers you set the
the Tri-Way to bridge only. Problem is, I cant find a manual. Legacy's site ( Manual Coming Soon.I say call them and ask for a manual to be emailed to you or mailed.

    • Some times the accessories (the keyboard) for the computer kan bee used as "standalone" you just insert the wire provided.
    • Other times you need a "driver" for the accessories can work. when you have that maybe you need a software for the accessories kan play
    I found this site where you can find manuals to your keyboard :
