1 – MAINS IN – Power In & POWER Switch
The Classic450’s auto-sensing switch-mode power-supply
accepts any mains voltage from 90 to 240 volts – you do not
have to change settings, fuses or anything else. Simply connect
a standard IEC three pin connector to the local mains voltage,
and you are up and running. This is particularly handy when you
use the Classic450 on a tour.
The ground pin of the power-supply unit (PSU) must be
connected in order to avoid voltage differences between
e.g. the PA and the Classic450.
2 – SPEAKER OUT
Use the SPEAKER OUT combo connector for connecting the
Classic450 to your cabinet(s). You can use a speaker cable with
either Speakon or ¼" jacks. Do NOT use instrument cables!
The Classic450 can be used to drive any cabinet combination of
up to three RS 210/212/410 cabinets or up to two 8 Ohm
cabinets of another brand. RS cabinets have Speakon inputs.
