1. Power:
This switch turns the AC mains On or OFF.
2. Voltage: Select either110V- 120V/220V-240V for your local voltage level. Please check your local voltage for user reference.
3. Fuse: When using with 220V-240V/50Hz for T5.0AL/250V fuse, using with 110V-120V/60Hz for T10.0AL/250V fuse.
4. AC input: 3-Pin ground cable connect the unit to external AC Power Supply.
5. Remote Bypass Setting.
6. Selectable 70V and 100V constant voltage speaker output
7. 4 ohm / 70V Button: Leave this switch in the up position if you are connecting 4-ohm or 8-ohm speaker circuit(Stereo mode).
Depress the button to connect a 70V speaker circuit.

Stereo/Bridge Button
:
For stereo, or dual-zone mono operation, at 50 Watts per channel leave this in the up position. To combine
(i.e. Bridge) the two into a 100-Watt mono amplifier, depress the button. In Bridge mode, the 4 ohm / 70V button must be in the 4
ohm / 70V button must be in the 4 ohm position(depressed) to allow for the 8-ohm speaker circuit, not4-ohms! In bridge mode,
an amplifier encounters a load that is about one half of its actual value a 4-ohm load would therefore be 2-ohms to a bridged
amp and if the amplifier isn’t designed to run Safely into such a low impedance (which the CA1250 is not) damage may occur to
the amplifier. We do not recommend connecting a 70V Speaker circuit while in Bridge mode as the output will be at 140V and
the sound can be distorted.
