DaytonAudio DTA-2 Manuale utente

Model: DTA-2 User Manual

Introduction:

The Class-T Digital Audio Ampliﬁer is designed around the Tripath TA-2024 IC. The TA2024 is a

15W/ch continuous average two-channel Class-T Digital Audio Power Ampliﬁer IC using Tripath’s

proprietary Digital Power Processing™ technology. Class-T ampliﬁers offer both the audio ﬁdelity

of a Class-AB ampliﬁer and the power efﬁciency of a Class-D ampliﬁer.

This PCB ampliﬁer 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 ampliﬁer into an existing speaker cabinet.

Features:

• Class-T architecture

• “Audiophile” Quality Sound

• 0.03% THD+N @ 9W, 4Ω

• 0.10% IHF-IM @ 1W, 4Ω

• 11W @ 4Ω, 0.1% THD+N

• 6W @ 8Ω, 0.1% THD+N

Package Contents:

(1) Class T Digital Audio Ampliﬁer 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 ampliﬁer 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

• High Efﬁciency

• 81% @ 15W, 4Ω

• 90% @ 10W, 8Ω

• Dynamic Range = 98 dB

• Over-current protection

• Over-temperature protection

• High Power

• 15W @ 4Ω, 10% THD+N

• 10W @ 8Ω, 10% THD+N

The schematic diagram above 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.

• 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 ampliﬁer PCB using the 12"

ribbon cable

• Mount the PCB using adhesive pads or with a zip tie
