Thank you for choosing the miniDSP HA-DSP DSP-enabled portable headphone amplifier. The HA-DSP is a:
•
DSP processor. The HA-DSP incorporates a powerful set of features. In addition to gain, bass, and treble
controls, it features 10-band parametric EQ and FIR processing on each channel and a powerful and
highly configurable cross-feed capability.
•
DAC. The processed digital audio data is fed to a 32-bit ESS Sabre DAC. The USB input also supports
direct DSD (direct stream digital) playback, where DSD audio (DoP) is fed directly to the DAC chip. (DSP
processing is disabled while playing DSD.)
•
Headphone amplifier. A Texas Instruments TPA6120 provides up to 100 mW in each channel into 32
ohms with low distortion and a signal-to-noise ratio of 112 dB.
Four DSP processing configurations are stored on-board and can be selected using the button on the front panel
or with the Android control app. The HA-DSP features three inputs
–
USB, digital optical, and analog
–
allowing it
to be used with almost any portable music device.
