22 Watt Audio Amplifier

The 22 watt amplifier not only amplifies your sound, but also includes both Treble and Bass controls to enhance any speaker system. Although it was designed to be used with all Dallee Electronics Inc. sound systems, it may also be used with other systems. The amplifier is designed for use with an 8 ohm, or higher, speakers. The amplifier is small enough to fit most 'O' gauge and larger type trains. Heavier wattage speakers, as available from Dallee Electronics, are recommended. The maximum DC input is 25 volts. Typical operation is achieved utilizing 12 to 24 volts. The highest output power is achieved with 24 volt DC input power by easily installing a 24VPS Regulated Power Supply. Proper ventilation is required to achieve the maximum output power. For most applications, the full power will not be necessary but it's always nice to have it available!

2. Install the gray wire of the speaker connection on a Dallee Sound System in the 3rd connector just to the right of the power.
