HiFiBerry Amplifiers

 

HiFiBerry Amplifiers

HiFiBerry Digi boards add digital (SPDIF/Toslink) audio interfaces to your Raspberry Pi. SPDIF is a 2-channel digital audio interface.

All of our boards support not just CD quality audio (44.1kHz/16bit) but also high-resolution audio playback with 192kHz/24bit. The boards shown here work with all Raspberry Pi’s that are equipped with the 40-pin GPIO header.

Digital amplifiers

These amplifier modules already include an high-quality 24bit/192kHz DAC. You don’t need an additional HiFiBerry DAC to use them.

MiniAmp

Our smallest amplifier for Tinkerers. It comes in the Pi Zero form factor, but can also be used on the full-size Raspberry Pi boards.
With it’s 2x3W output power it isn’t designed for large rooms. However, for many applications, e.g. desktop speakers even this output power is enough.  It will be powered directly from the Pi. Your 5V USB power supply is powerful enough for the Pi and the Miniamp.

Amp2

This small but powerful amplifier can deliver up to  60W output power. That’s quite a lot – even if you might not think so. It’s not the amplifier you would use for a concert in a stadium, but it’s perfectly fine for almost any application in apartments of usual sizes. You don’t think it’s enough for you? Try it out!

Beocreate 4-channel amplifier

 

Developed originally to re-use older B&O speakers, the Beocreate 4-channel amplifier can also be used as an amplifier for “normal” speakers. While you can use it as a simple 2-channel amplifier, it shows it’s full potential if you use the integrated digital-signal processor to implement crossovers, room equalisation filters or other interesting stuff.
It delivers up to 2x30W and 2x60W output power.

Analog amplifiers

Analog amplifiers do not include DAC. They can’t be used standalone with the Raspberry Pi, but require an additional  HiFiBerry sound card with an analog output header as the DAC+ ADC Pro.

Aamp60

This amplifier add-on module is similar to the Amp2, but without the Digital-to-analog converter.  It can deliver up to 60W output power.

FAQ

Q: Can I combine the Amp2 with another card like the DAC+ ADC?
A: As the Amp2 already includes a DAC, you can’t. The Raspberry Pi supports only a single sound card. However, you can use the AAmp60 in combination with some sound cards as the DAC+ ADC Pro.

Q: My speakers have a xxx W rating, will they work with any of your amplifiers?
A: The power rating of speakers is one of the most misleading specifications in audio. It only tell you how much power this speaker can accept without being damaged. But can you still combine a 5W rated speaker with the Amp2 that delivers 60W? Yes, you can. The output power only shows you the maximum output. Compared to a classical analog amplifier this mean, you would turn the volume to the maximum. We don’t know a lot of people who really do this.

Q: How much power does it consume?
A: Modern Class-D audio amplifiers requires very few energy. If not music is playing, power consumption is very low. If you’re playing music, in most use cases, power consumption will be in the range of 1-10W – not even close to the maximum power.

Q: Can I bridge the outputs to get more power out of it?
A: No, you can’t. The amplifiers already use a bridged design internally.

Q: But I really need 30% more power!
A: Probably you don’t. If the output volume is too low, 50% more power won’t bring you near the power you really need. To double the maximum volume, you need 10 times the output power. Even doubling power will be barely noticeable at all.
