Here's a well-built, superbly engineered receiver designed for those who want exceptional sonic performance and easy-to-use convenience features, but don't need Dolby Pro Logic. It offers notably reduced negative feedback, thanks to new amplifier circuitry, and is capable of effortlessly driving 4-ohm speakers - uncommon for a receiver. The TX-8511 also gives you 4 audio inputs and A/V switching - so you can copy from Video-1 to Video-2 at the touch of a button. Plus you also get A/B speaker switching, 30 FM/AM presets, Multiroom capability, and much more.

A perfect receiver/amp for your whole-house audio system. This device could drive up to eight pairs of average in-wall or in-ceiling speakers. (When each zone is equipped with impedance matching volume controls.)

  • Audio sensing, to allow the amplifier to be turned on from an external source audio signal
  • External voltage (3-30 volts AC or DC) to trigger the unit on or off
  • Individual left and right channel sensitivity trim pots
The NV-P2100 delivers high efficiency stereo amplification at 200 watts. The amplifier is compact, powerful, and cooler than other amplifiers. High efficiency technology means you’ll use less operating power with the NV-P2100 than with other amplifiers. And output relays eliminate external interference and protect speakers from dangerous voltages, unwanted pops, and extraneous noise.

AUTO AMP 15
Auto Switching Music Amplifier

  • Stereo 15 watts RMS / 45 watts peak
  • Connects to source device line level audio outputs
  • Senses source device operation via audio or video trigger
  • Compatible with amplifiers of up to 600 watts per channel
  • Includes 24V AC Power Supply
TV Power Amplifier with Automatic Switch

The Auto Amp 15 enables you to use a single pair of in-wall speakers to safely play sound from both a whole house system and a local television. Both the TV (or other audio source with line-level audio output) and the whole house system connect to the Auto Amp 15 (typically hidden behind the TV). When the television is off, the whole house music system is automatically routed to the speakers with pure direct pass-through. When someone turns on the TV, the Auto Amp 15 automatically disconnects the music system and turns on the built-in high-current TV power amplifier.

Now enjoy your television in stereo with real power pushing your in-wall speakers! When the TV is turned off, the music system is re-connected to the in-wall speakers automatically.
