Selecting the right product
In keeping with our goal to be innovative, Ngineering is
delighted to announce our newest product family, Little Sounds.
With over 1-1/2 years in development, we chose the product name for 3
1. For reasons of scale, we believe realistic sound effects should draw you in, not push you away. After discussions with many, many hobbyists, the general consensus seems to be that
sound effects are typically way too loud. Example: At a 10-foot distance, you
are 1/6 of an HO mile away. How noticeable would a sound really
be? In N scale that would be over 1/4 of a mile!
2. Our Little Sound module
is only 1.38" long x 0.60" wide x 0.25" high, with up to
5-minutes of pre-recorded 16-bit digital sound. It will fit just about anywhere.
3. Our basic N8300 & N8301 Little Sound modules with a pre-recorded sound
effect, and speaker sell for less than $20.
And... to support larger scales and/or environments
with background noise, we are also pleased to announce Little Bigger Sounds
as a supplementary product family (at a slightly bigger price). This
product uses the same Little Sound module reprogrammed to provide direct audio
output to our external
1.5-Watt Amplifier module, to boost output. This amplifier is included in the
package. Little Bigger Sounds (N8500, N8501 &
N8502) are available with 3 different speaker sizes. N8503 is our Sound module
configured for output to any standard amplifier. Included in the package is a
volume control potentiometer (with knob) and a 10uf electrolytic filter
All products have on-board input voltage regulation and volume
control (the N8503 has an external volume control)..
The N8300 and N8031 products are programmed to directly drive
a small 8-ohm speaker. Typical audio output from the internal 1/2-watt
amplifier is in the range of 40-60 dB
(about the level of two people quietly talking). These products are best
suited for home layouts or dioramas in a quiet environment. Typical modeling
scales are Z, N HO and S.
The N8300 includes the 15 x 24mm oval
speaker that is well suited for small-scale rolling stock or very tight
modeling situations. This oval speaker is like the ones used in cell phones
and has surprising tonal quality.
The N8301 includes a larger 28mm
(about 1.10" diameter) round speaker which has greater dynamic range
and is better for general stationary sound effects in quiet environments.
N8400 is an upgrade from Little Sounds to Little Bigger
Sounds. For those applications where the Little Sound module just doesn't
quite produce enough audio volume, we will reprogram the sound processor
chip on the module for external (DAC) output to function with our external
1-1/2-watt amplifier. The customer unsolders the module(s) and returns
it(them) to us. In turn, we will cleanup the solder pads and reprogram and
retest the module(s) and repackage as a Little Bigger Sound version with the
N8415 Amplifier included in the package. This upgrade can be ordered by
clicking on the Sound Accessories button below and then
scroll down to the Upgrade item and select the quantity to
upgrade in the Cart window. Proceed to checkout as normal.
Or, click here.
The N8500 includes the 15 x 24mm speaker and will output substantially
more (85+ dB) audio sound due to the addition of the 1.5-watt amplifier.
The sound module is programmed specifically to output audio DAC (digital to
analog conversion) for input to the external amplifier. With careful component placement, the sound module and amplifier module and
speaker with speaker box can be placed inside an N scale boxcar (with track
pickup rectification and flicker control capacitors), for operation in a
noisy (train show) environment. See details here.
The N8501 with the
28mm round speaker and amplifier will perform well for stationary sound
effects in HO and O scales and layouts in public (noisy) venues.
with the 52mm round speaker has exceptional dynamic range for its 2.10"
diameter and is intended for really big sound effects (a thunderstorm at the
back of a layout, or a sawmill on display). It is also well suited for
garden scale railroading.
is our Little Sound module configured for Bigger Sound DAC output to a standard
amplifier input and includes an external volume control with filter
capacitor. This configuration will allow connection to large amplifiers for
applications requiring high output volume.
