43. Zone 1-6 low impedance speaker terminals
Connect this terminal to the + terminal of either an 8
Ω
or 16
Ω
speakerload.
In case of using several speakers, make sure that the total speaker load is the same as the impedance of
the corresponding terminal. The total power rating of the low impedance speakers connected to this
terminal summed, should be at least 30W.
44. Zone 1-6 100V high impedance terminals
Each zone has its own output terminal. Connect this terminal to the + terminal of your 100V high
impedance speaker load.
In case of using several speakers make sure all speakers are wired in parallel.
The total power rating of the high impedance speakers connected to this terminal summed, should never
exceed 30W.
45. AM antenna connector
Connect your AM antenna to this connector.
46. Input 4 tape RCA input
Use to connect a tape recorder output.
47. Input 4 CD RCA input
Use to connect a CD player.
48. Input 4 aux RCA input
Use to connect a line level device.
49. Combo input 3
Combo input for channel 3. Accepts balanced or unbalanced inputs.
50. Combo input 2
Combo input for channel 2. Accepts balanced or unbalanced inputs.
Operation
Installation
Remove all packing materials from the MA-630TU. Check that all foam and plastic padding is removed.
Secure the equipment into a 19" rack if preferred. Connect all cables.
Set Up and Operation
Before plugging the unit in, always make sure that the power supply matches the product specification
voltage. Do not attempt to operate an 115V specification product on 230V power, or vice versa.
Before powering up the first time, make sure the AC-selector switch is set to the proper voltage.
Damage caused by connecting the amplifier to improper AC voltage is not covered by any warranty.
NOTE: Always turn off and disconnect the amplifier from mains voltage before making audio
connections. Also, as an extra precaution, have the attenuators turned down during power
-up.
