Nigel B Design NB-2052PL

Features:

• 45 watts (RMS) into 4 or 8 Ohms single or multiple speaker installations for superior sound output in mono or stereo modes.
• Fast Automatic Detention Circuit (ADC) eliminates sound clipping & saves energy.  The cool running NB-2052PL turns itself on in less than 2 ms of detecting an audio signal.  When no audio signal is detected, it automatically turns itself off after about 30 seconds unless audio is restored before the cutoff period, at which time the amplifier will repeat the Active Mode until no signal is detected.
• Automatic internal configuration of the line input - Internalcircuity enables the user to configure the amplifier to be used in eitherbalanced or unbalanced modes, depending on the connections used.  Acceptsbalanced or unbalanced inputs for stereo or mono operation.
• Two-way RS-232 port for total control.  The amplifierprovides two-way communication supporting almost any control device includingAMX®, Crestron® or Aurora Waci® control devices.  The amplifier canreceive and confirm the following commands: amplifier volume - left channel,right channel (for balance) up and down, mute and speaker connectionconfirmation. As on and off are automatic functions of the amplifier, there isno need to provide these from the RS-232 Port.  In addition, softwarecontrollers that use Global Cache, such as Stardraw, allow these functions tobe made from any computer.
• Phoenix® type terminals for fast connections
