Our range of items is growing steadily, which led to numerous questions concerning purchase decisions lately. To give you a better overview of our assortment, we implemented a comparison feature on our website. With this function, you can compare selected sound cards.

Sampling rate\/ resolution:
\n<\/strong>Generally, the chips can sample with up to 50MHz, the DACs with up to 384KHz. The chips recognize the sampling
\nrates of the sound cards automatically. The sampling rate is limited to 192KHz by the Raspberry Pi.<\/p>\n

Signal-to-noise-ratio (SNR):
\n<\/strong>Ratio between the strength of the signal and interferences (112db signal = 1db interference noise)<\/p>\n

Output:
\n<\/strong>Stereo (2.0): 2-channel analogue stereo
\nStereo (2.1): 2-channel analogue stereo + subwoofer output
\nRCA digital: Digital output via RCA, which is later split into audio-channels by the amplifier.
\nTOSLink: (digital) optical output
\nAllo Volt Amo header: dedicated connection for “Volt Amp” by Allo
\nBNC: connection for radio antenna<\/p>\n

Output power:
\n<\/strong>Power in watts (for Amps) for given resistance
\n(Amps dedicated for an optimal impedance of (e.g.) 4 ohms can also be used for
\nspeakers with higher or lower resistance, hits just changes the final output
\nvolume, given the less or more power used to overcome the resistance)<\/p>\n

Clock generator:
\n<\/strong>Synchronizes the output signals of the sound cards to reduce interferences.<\/p>\n

Kali: external clock generator for Allo Piano DAC<\/p>\n

Additional connections:<\/strong>
\nI2S Header: Is a direct connection to the pin-header or the Raspberry Pi. You can use it to connect
\nadditional hardware to the RPI, like the rotary encoder. Not all pins on the I2S-header are available,
\nsince some of them are already used by the the sound card itself.<\/p>\n

GPIO: In the list, this term is used to describe preconfigured combinations of pins on the I2S-header.
\nThey are soldered to separate connectors. Using these connectors, you can add extra hardware – like
\nthe Allo Volt Amp to the Allo Piano DAC – without the effort of finding and soldering the correct pins yourself.<\/p>\n

Piano audio out: dedicated GPIO connections for the Allo “Volt Amp”<\/p>\n

IR-receiver:<\/strong>
\nIR: infrared
\nVishay TSO: optional connection for IR-remote<\/p>\n

Rotary encoder:
\n<\/strong>Used to control volume, tactile function included (i.e. for start\/ stop)<\/p>\n

This is a dedicated additional connection. You can still connect a rotary encoder to cards without this connection by
\nsoldering it to the dedicated pins on the I2S-header.<\/p>\n

Hardware features:
\n<\/strong>EEPROM: Used to save configurations (ATTENTION: this feature is still in development on the Raspberry Pi).<\/p>\n

Galvanic Isolation: protection against interferences by radio frequencies<\/p>\n

ALSA controls for sound card (driver):<\/strong>
\nALSA: Is a driver for your sound card, that is based on Linux. You can use it to change settings, such as
\ngain or volume.<\/p>\n

Analogue Boost: gain (up to +6db); The gain regulates the sound cards input sensitivity. It should be set
\nto the highest possible setting without distortion at your sound cards highest output volume.<\/p>\n

Playback Boost: additional gain (up to +0.8db)<\/p>\n

Max2Play Software features:<\/strong>
\nCustom plugins: Sets your sound card to the optimal preferences and adds the web interface to change these
\npreferences to your Max2Play user site.<\/p>\n

ALSA web control: Lets you change the configurations of your sound card easily via web-interface.<\/p>\n

Power supply:<\/strong>
\nSound cards with their own power supply power the Raspberry Pi as well, so you still only need one power supply.<\/p>\n[\/spb_text_block]\n","protected":false},"excerpt":{"rendered":"
