Introduction:The Class-T Digital Audio Amplifi er is designed around the Tripath TA-2024 IC. The TA2024 is a 15W/ch continuous average two-channel Class-T Digital Audio Power Amplifi er IC using Tripath’s proprietary Digital Power Processing™ technology. Class-T amplifi ers offer both the audio fi delity of a Class-AB amplifi er and the power effi ciency of a Class-D amplifi er.
This PCB amplifi er is ideal for any audio enthusiast who enjoys building and modifying speaker systems. The applications are virtually limitless since this tiny PCB measures a mere 2-11/16" x 1-5/16". Build your own speakers or incorporate the amplifi er into an existing speaker cabinet.
Features:• Class-T architecture• “Audiophile” Quality Sound • 0.03% THD+N @ 9W, 4 • 0.10% IHF-IM @ 1W, 4 • 11W @ 4, 0.1% THD+N • 6W @ 8, 0.1% THD+N
Package Contents:(1) Class T Digital Audio Amplifi er PCB(1) Volume control PCB with 12" ribbon cable(1) LED power indicator(2) 12" Speaker Wires (Red & Black)(2) 12" Power Wires (1 Red & 1 Black)(2) 12" LED Wires (1 Red & 1 Black)(2) Output Capacitors(2) Ferrite Cores
Assembly:• Remove the amplifi er PCB from the static protective
sleeve using static protective gloves or wrist band• Solder the speaker wires to the PCB at points “A & B” • There are polarity marks (L+/- R+/-) printed on
the bottom of the PCB• Solder the power leads (if desired) at point “C” • There are polarity marks (B+/B-) printed on the
bottom of the PCB• Solder the LED to the PCB at
point “D” or use the LED wires to place the LED where desired
• The anode (+) lead is long, the cathode (-) is short • Mount the LED from the bottom of the PCB • Insert the anode through the left eyelet and the
cathode through the right eyelet• Wrap each speaker wire through a ferrite core; one
wrap per core is all that is required• Solder the speaker wires to the speaker terminals• Solder an output capacitor across the speaker terminals in parallel with the speaker wires• Connect power via the power leads or DC power jack; we recommend a 12VDC, 2000mA power supply similar to Parts Express model 120-052• Mount the volume control in the desired location and connect to the amplifi er PCB using the 12” ribbon cable• Mount the PCB using adhesive pads or with a zip tie
Schematic Diagram:The schematic diagram on back is provided for reference. It illustrates the TA-2024 IC and the input and output circuits on the PCB. CDO are two output capacitors. These capacitors are ideally placed close to the speaker terminals or crossover input terminals as appropriate.
• High Effi ciency • 81% @ 15W, 4 • 90% @ 10W, 8• Dynamic Range = 98 dB• Over-current protection• Over-temperature protection
• High Power • 15W @ 4, 10% THD+N • 10W @ 8, 10% THD+N
