45 WATT MONO / STEREO AMPLIFIER
45 Watts RMS Mono / Stereo Output into 4 Ohms gives you plenty of output for one or two 4 or 8 Ohm Speakers. In Multiple Speaker
Installations, 8 Ohm Speakers work best in this type of Installation. Information on Speaker Wiring is published on our Web Site
www.nigelbdesign.com under “Tech Manuals,” which explains why 8 Ohm Speakers are the preferred choice in these situations.

Requires NB-PS75 AC Power Supply
Internal circuity enables the user to configure the Amplifier to be used in either Balanced or Unbalanced Modes depending on the connections used.
Shown below are the different Line In Connections that allow the Amplifier to accept either Balanced or Unbalanced Stereo, or Balanced Bridged
Mono Inputs, depending on the user's requirements.

ENERGY SAVING FEATURE
The Amplifier features our ADC (Auto Detection Circuit) that reduces the power Consumption by a significant amount when the Amplifier is not in use.
ADC works within 2 milliseconds of receiving an audio signal and the Amplifier will stay on until no Audio Signal is Present. This way no On/Off Switch
is needed. As soon as Audio is again present the Amplifier will resume operation. After 30 second the Amplifier will go off until activated again.
All our Amplifiers use (Automatic Detection Circuit) that saves Energy. All our Amplifiers
meet an Energy Star Rating allowing us to Display the Energy Star Logo on our Products
Amplifier reduces Engery Use from
4.5 Amps to .025 Amps in "Stand By" Mode
