It is designed for guest rooms, offices and other spaces that need a small local speaker amplifier with a user volume control.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/db-tpa1a.jpg\" alt=\"RDL DB-TPA1A 3.5 W Format-A Decora Amplifier\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe DB-TPA1A receives stereo audio and 24 Vdc power through a rear-panel RJ45 jack; the left and right signals on pairs B and C are summed to mono and amplified. An internal VCA controlled by the front-panel volume knob sets the output level, and turning the level to minimum switches off the Class D stage for an energy-saving sleep mode. The speaker output connects on a detachable terminal block and drives a 4 or 8 Ω speaker. The DB-TPA1A has a black front-panel laminate for darker wall finishes and AV furniture.
