Class-T Digital Audio Amplifier TK2050-6
Salve a tutti,
non è proprio "realstereo" ma questa scheda potrebbe essere interessante per un eventuale ampli a 6 canali per l'ascolto di sacd. che ne dite?

Usage Notes:
We recommend bringing up the amplifier as follows:
1. Connect loads to the individual channels. Note that unloaded channels are allowed, as the
Tripath application circuit is tolerant of very high impedances. Also note the polarity markings on
the outputs.
2. Mute the amplifiers by sliding SW1 to the right (toward the outputs).
3. Connect the input sources to RCA connectors J21-J26. Note that channel pairs “cross over” to
the corresponding outputs – that is, Input 1 is to the left of Input 2, but Output 1 is to the right of
Output 2. This is noted on the board silkscreen.
4. If you are using an external 5V supply, connect it to J27 (+5) and J29 (GND), and remove J53. If
you are using the on-board 5V supply, simply leave J53 in place.
5. Connect the main power supply to J28 (Vcc) and J30 (GND).
6. Bring up the power supply (supplies). If an external 5V supply is used, bring it up before the main
supply. Both power supply indicator LEDs should be illuminated and green. If either of the
supply LEDs are unlit or the FAULT LEDs are lit, recheck your supplies and connections.
7. Unmute the amplifiers by sliding SW1 to the left (toward the inputs). The HMUTE LEDs should
turn off.
8. The amplifiers are now ready for use.
Power Supply Connection
This board requires a single power supply rail (and ground) to operate. The minimum working
voltage on this rail is 7V, and the maximum is 36V. For maximum power operation, the power supply
should have at least a 10 Amp rating. The TK2050 chipset also requires a 5 Volt supply for the
power processor logic, but this 5V supply is generated on-board by the linear voltage regulator at
U10. Note: this regulator is limited to 35V input. For operation of the EB-TK2050-6 at it’s absolute
maximum rating of 36V, the on-board 5V supply must be disabled (at J53) and the an external +5V
supply (1A) must be used. Rail voltage is connected at J28 (+) and J30 (GND).
