Krell Industries MDA-300/500 manual Input and Output Connections

D.INPUT AND OUTPUT CONNECTIONS

CAUTION:Whenmaking connections to this component or any other, makesure ttie poweramplifiers are OFFand the preamplifier is in the MUTEor STANDBYmode.

1.Connectthe speaker cables to the output terminals of each amplifier. The MDA-300/500sutilize two sets of parallel 5 waybindingposts for the left and fight amplifi- ers. This con_figuration makescable connectionsand-bi- wiring simple.

NOTE:The binding, posts are of the highest quality but

w.ill breakif over.tigla.tenedIn. ..se.rt wireor spadelug into the connectoranc~tigt~ten until there is no movement fromthe cable.

CAUTION:Makesure all cable terminations are of the

highest quality, free fromfrayed ends, shorts or cold solderjoints.

2.Connectthe interconnect cables fromyour preampli- fier to the input of each MDA-300/500.

The wiring to and from the amplifiers, and all compo- nents in general, should be arrangedin a neat, organized manner.Specifically, ACwires should be separated from audio wires. This practice avoids humor ottier unwanted noise frombeing induced into the system.

The MDA-300/500shave balanced and single-ended inputs. The balanced inputs use 3-pin XLRconnectors and the single-ended inputs use standard RCAconnec- tors.

CAUTION:Use only one input to the amplifier at a time.

The MDA-300/500sare shipped with. shorting pins in the ~LRinputs. These pins shoi~ld remain in the XLRinputs it you are operating the MDA-300/500sin the single- elided mode.Whenthe shorting pin is inserted, pin 1 and pin 3 are. shortedtogether. Thesfiorting pins mustbe removecl to connect the MDA-300/500sfor balanced operation.
