A 40 Watt stereo Local Source Amplifier designed to fit into a standard single gang box to amplify any local audio source, through that zones speakers. Available in two versions.

For an individual zone, use LSA40S which includes a local power supply.

Or power up to four LSA40 amplifiers with the LSA40PDS 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.

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.

If you enjoy high-quality sound, this is one receiver that wont disappoint. Its high-current, low-impedance amplifier sports an oversized, shielded transformer, large, high-quality, filter capacitors, a massive extruded heat sink, and discrete output stage circuits that keep sound from distorting at high temperatures.It also boasts cassette-tape monitoring, 4 audio inputs, A/B speaker switching,APR, 30 FM/AM presets, preset scan, a sleep timer, and more.
