1. Channel Input (unbalanced RCA): Use an RCA cable to connect an external audio source to this
input. The left and right input signals will be summed to mono.
2. Speaker Output: This output sends the main/master signal from DN-280 to your external speaker.
Connect this output to your speaker using the included Euroblock connector and speaker wire (not
included). The power of the output is less than 60 W (without distortion). See
Setup for more
information.
Important: Connect only one speaker type to the speaker output. Use only 70V/100V speakers designed
with step-down transformers with the 70V/100V outputs. Do not connect a low-impedance speaker (4
Ω
)
to the 70V/100V output terminals, as this may result in damage to your amplifier and/or speaker.
3. Vents: For proper performance, keep the vents clear from obstructions to allow air to flow.
4. Power Input: Use the included power cable to connect this input to a power outlet. Make sure DN-
280’s Power Switch is set to off when connecting or disconnecting the cable.
5. Fuse: If the unit’s fuse is broken, lift this tab to replace the fuse. Replace it with a fuse that has an
appropriate rating (following the specifications located on the rear panel of DN-280). Using a fuse with an
incorrect rating can damage the unit and/or fuse.
