1.5-Watt Amplifier  N8415
If you need an small speaker with good frequency response, our little oval gem is an excellent choice. It has the standard 8-ohm impedance so it will work with most sound applications/amplifier outputs. While it is spec'd at a maximum input power of 1 Watt, we have tested it for varying (not continuous) power inputs up to 1-1/2-watt with no noticeable performance degradation. This speaker is ideal for N scale rolling stock applications, or anywhere that limited space is an issue. The speaker includes a peel-off sticky mounting ring that lets it easily bond securely to any smooth mounting surface.

 28mm Speaker  N8328

     1.5-Watt Amplifier
   52mm (2.1") Speaker
  28mm (1.10") Speaker
    15 x 24mm Speaker









For applications where larger sound output is needed, this 28mm (1.10" diameter) speaker is perfect for small to mid size scale situations. Perfect for stationary sound effects in the smaller to mid-scales and excellent performance in HO rolling stock applications. It can easily handle 1-1/2-Watts of power continuously. Like the speaker above, it is manufactured using a highly efficient rare-earth magnet which greatly enhances performance while keeping overall size to a minimum. It also has a peel-off  sticky mounting ring for easy installation, and protective metal speaker cone guard and screen.



























Also manufactured with a high-efficiency rare-earth magnet, this little 2.1" diameter speaker provides absolutely incredible sound output quality. It includes a very pliable speaker cone mounting ring to allow the cone maximum excursion to produce those deep base sounds (such as a thunder storm) and a secondary voice-coil suspension ring to maintain perfect coil alignment during those low-frequency large sounds. This speaker is a perfect choice for very large scale rolling stock applications, or situations where a "big" sound is required.
This little circuit is the backbone of our Little Bigger Sound family of products. When our Little Sound module is alternately programmed to provide DAC (digital to analog converted) sound output, this little jewel takes that signal and provides very clean and distortion free amplification of 1-1/2 Watts to an 8-ohm speaker. Unlike a typical Class AB amplifier, this circuit meets Class D amplifier specifications and doesn't require large (typically 250uf or greater) capacitors on the speaker outputs. As a result, it can fit in applications where space is very limited, but good performance is required.

Our N8600 Proximity Detector uses transmitter and receiver sensors with a very narrow 15 degree detection angle to locate object position and movement. The output from these sensors is processed through Ngineering’s proprietary electronics to compare the signal to an adjustable precision reference voltage. A knob is provided for this adjustment. This provides precision adjustment of detector range to within 1-1/2 inch accuracy in distance. An LED indicator establishes a visual “trigger” position for detection distance setup. Once the distance is set, objects from that distance down to 3 inches will be detected. Objects beyond that setting will be ignored. A small slide switch is provided for selection of two basic range modes: 3 inches to 3 feet, and 3 inches to 10 feet. A sturdy PVC mounting bracket is provided for easy installation.

The DCC Trak-Pak combines several of our products to provide easy adaptation of our lighting or sound effects to rolling stock for Z, N and HO scales. A complete list of what's included can be found by clicking on the Contents link in the More Info table above. We have used this product in an N scale cattle car to demonstrate our Little Bigger Sounds effect for cows, using our sound board, amplifier board and speaker, all located inside the car, running on track power. The effect is quite dynamic. To see the details of this installation, click on the Example of use link in More Info above. The Using link above completely covers adaptation and installation.
Now you can have special effects like lighting and sound turn on as you walk around your layout, display or diorama.
