Common questions about manuals, registration, and support for this brand.
A red LED indicates a potential issue such as high DC offset voltage or waveform clipping. You should reduce the output level, ensure the amplifier is not overheating, and correct the DC offset of the source device. If it won't turn on and blinks red, an error requiring authorized dealer service has occurred.
To enable software updates, connect your amplifier to a network router or switch using an Ethernet cable connected to the rear panel. The amplifier will download software updates as necessary if it has an active internet connection.
No, Boulder does not recommend or provide provisions for banana plugs, as they can lose spring tension over time, increasing contact resistance and distortion. You should use spade terminals that accept 0.250-inch (6 mm) diameter binding posts.
