Very small, high sound quality, new Class-A
amplifier module with CANAAN CS6A4989 IC.
A separate power supply is required.
To assist it, there are 2x3 470uF/16V NICHICON
"Fine Gold" power supply capacitors on board.
Dimensions: 100x60x25mm
This module fits in 40mm (1U) high enclosures.

Very small, high sound quality, new Class-A
amplifier module with CANAAN CS6A4989 IC.
It has 2x4 2.200uF/16V NICHICON "Fine Gold"
supply capacitors om board, ensuring enough
power reserve to feed 4ohms speakers.
Just a 5 - 25VA, 2x 7V transformer is required.
Ideal for reasonal sound levels in your student flat,
living/bed room, offfice, etc.
Dimensions: 100x75x25mm
This module fits in 40mm (1U) high enclosures.

Very small, high sound quality, new Class-A
amplifier module with CANAAN CS6A4989 IC.
A complete power supply with 5VA 115/230V
encapsulated toroidal PCB transformer and
2x2 2.200uF/16V NICHICON "Fine Gold" supply
capacitors ensures enough power reserve
to feed even the most demanding
earpieces and headphones.
With a pair of LM317/337 voltage regulators
we regulate the supply voltages to the IC
to ensure the most perfect performance possible.
This amplifier design meets the highest
quality headphones available today.
It doesn't need to look complicated to be good !
Dimensions: 100x160x25mm
This module fits in 40mm (1U) high enclosures.

Very small, high sound quality, new Class-A
amplifier module with CANAAN CS6A4989 IC.
A complete power supply with 15VA 115/230V
encapsulated toroidal PCB transformer and
2x 10.000uF/16V supply capacitance ensures
enough power reserve to feed 8ohms loads
out of this amazing good power amp IC.
Feed it with Streamer, PC, Tablet or Smartphone.
While driving high efficient speakers you
even could reach very impressive sound levels
in a student flat, living/bedroom, office, etc.
Dimensions: 100x160x29mm
This module fits in 40mm (1U) high enclosures.
The IC can be cooled by mounting it to the bottom.

Very small, high sound quality, new Class-A
amplifier module with CANAAN CS6A4989 IC.
A complete power supply with 25VA 115/230V
encapsulated PCB toroidal transformer and
2x5 2.200uF/16V NICHICON "Fine Gold" supply
capacitors ensures enough power reserve
to feed 4ohms speakers to the max.
Feed it with Streamer, PC, Tablet or Smartphone.
While driving high efficient speakers you
even could reach very impressive sound levels.
Using it in bridged mode you possibly could
reach around 15Wrms/8ohms in Class-A !
Dimensions: 100x160x40mm
This module fits in 80mm (2U) high enclosures.
We recommend to use a heatsink.

Based on Texas Instruments LM4766/T IC
We have types with or without integrated Power Supply.
We also provide them with several types
of power supply capacitors.
These module can be sandwich mounted as well, also
i.c.w. PA-3886 modules. While doing so they form a very
compact 3- or multiway amp block where you
just need to connect a single transformer.

Where more than two PA-3886/PA-4766's are using one
supply, the capacitance of the "mother" is not enough.
To solve this issue, we made this booster board.
This extra capacitor board has the same size as a PS version (100x100mm) and can be mounted on top, between or
beneath. There are several qualities available.
The connection is made by 3x 1,5mm
solid copper rods exactly in the centre.
We recommend to use a booster module for
three or more speaker outputs.
You can also use these as stand alone capacitor bank.
For that function there is a 3-pole screw connector.
Note that it has a symmetrical (V- /gnd / V+) layout!

Sandwiched PA-3886PS + PA-3886 modules.
2x 80Wrms or 200+Wrms/8ohm bridged.
Size: 100x100x60mm.
Straight linear class A/B design:
 Below a 3-way example, 2x50 + 80Wrms:
PA-4766 (2x50Wrms) on top
PS-BOOSTER (capacitor bank) in the middle
PA-3886ps (80Wrms + power supply) at bottom
 Somehow active filtered systems sound 30-50% louder than passive filtered speakers.
Due to this effect the total output power of this example combination will be
as loud as a passive filtered speaker fed with around 250Wrms.
