The BeoCreate 4-Channel Amplifier
The Beocreate 4-Channel Amplifier is a very flexible DSP/DAC/amplifier combination board designed for high-quality music playback in combination with
passive loudspeakers.
FACTS
• Up to 180W output power (2x30W, 2x60W)
• Capable of driving up to four of 4-8 Ohm speakers (the two 60W channels
can drive 2 Ohm speakers)
• Fully controllable from the Raspberry Pi
• Sample rates up to 192kHz
• 4-Channel digital-analog conversion included
• Connects directly to the Raspberry Pi A+/B+/2B/3B/Zero, no additional
cables needed
• Only one 12-24V external power supply needed to power both the Beocreate
board and a Raspberry Pi, no need for an external USB power supply
• No soldering required, the Raspberry Pi can be plugged easily onto the
Beocreate board. Speakers can be connected via screw terminals
• Can work standalone (without the Raspberry Pi) as a digital amplifier.
However, to program the DSP, a Raspberry Pi is required

FEATURES
• 294MHz DSP with 16kB data RAM and 8kB program RAM
• 16 asynchrounous sample rate converters allow to handle dierent sample
rates on dierent inputs and outputs
• DSP can be fully programmed by the end user using Analog's SigmaStudio
(requires a PC with Microsoft Windows)
• nboard EEPROM allows to use the board standalone without a Raspberry Pi
• TOSLink input and output (up to 96kHz sample rate)
• 4 channel DAC supports sample rates of from 44.1kHz to 192kHz
• 2x60W and 2x30W Class-D output stages
• expansion connector allows to connect additional hardware
(access to Raspberry Pi and DSP GPIOs)
• can be used as a 2-channel sound card from the Raspberry Pi
• multiple devices can be chain-linked using SPDIF
(e.g. to implement an active 4-way stereo system)
CONNECTORS
• TOSLink input and output connectors
• 5.5mm barell jack and screw terminal for external 12-24V power supply
• 4x screw terminal to connect loudspeakers
• 34 pin expansion connector
• programming header (compatible with Analog Devices USBi interface)
