A set of four N gauge painted cows complete with preprogramed soundboard and speaker to create the sights and sounds of cows mooing, by Faller.Add the next level of authenticity, ambience and realism to your farm diorama or simply have some family fun with this set of four cows and sound effects capsule by Faller.The cows are regular model cows and can be placed anywhere at your discretion. The sound effect comes from a separate soundboard and speaker that can be hidden under the baseboard or in a suitable model building of your choosing. Wiring is simple and connects to a 12v DC or 16v AC auxiliary power supply.A switch is not included in the pack as there are a number of ways the sound effects can be triggered, from a simple on/off or 'push to make' switch to an automated system of reed switches combined with a relay, the choice is yours but needn't be complicated.Once supplied with power, the sound effect lasts for a duration of 5-25 seconds depending on the product and can be re-triggered at any time.There are two main components you will need to find a home for, a soundboard measuring 45 x 25 mm and a speaker measuring 35 x 20 mm. Neither component has a depth of more than 10 mm. A length of wire 170 mm long is already attached to the product for connection to a power supply or switch.Faller sound capsules are undoubtedly a simple and effective way to add another dimension to your layout or diorama.Are you choosing figures for an arts and crafts project?It may surprise you to know that the average size of an N gauge figure is just 1cm tall, great for N gauge model railways, not so great for larger arts and crafts projects. You can discover a great range of taller figures by searching for 00 gauge figures (twice the size of N gauge) or 0 gauge figures (four times the size of N gauge).
