Uses a BurrBrown PCM5102 digital-to-analog converter

The built-in BurrBrown PCM5102 digital-to-analog converter is capable of processing digital audio signals up to maximum 24-bit/96kHz resolution

High 160mW + 160mW output gain (at 32Ω load)

Fitted with a 160mW + 160mW high-output power amplifier (at 32Ω load). Lets you drive 600Ω-class headphones at full power.

Low distortion discrete power amp section

Uses a top-flight OPA 1652 operational amplifier to process audio signals with maximum purity. The discrete push-pull circuit achieves a very low distortion rate of 0.001% (at 100mW + 100mW output) which IC-based amplifier headphone circuits cannot match, thanks to meticulous component selection and an absolute insistence on sound quality. Every lesson TEAC has learnt about amplifier sound quality has been applied to the HA-501 in the pursuit of the very best listening experience, one that's wholly uncompromised in a mobile environment.

Dual-setting gain switch for use with high-impedance headphones

Fitted with a high/low gain selector which enables output gain to be matched to the impedance of the headphone being used. An indispensable feature for those who use top quality high-impedance headphones.

Accepts USB input from a PC/Mac

The HA-P50 accepts input from your computer via USB. Capable of high-resolution 24-bit/96kHz sound source playback when used with the TEAC HR Audio Player app (free to download) installed on your Windows PC/Macintosh.

Equipped with both optical digital/analog inputs

This versatile portable audio player employs an optical digital input terminal (*) that can be connected to a home audio system. The HA-P50 creates a high quality digital audio playback environment. With its dual-function AUDIO IN port (*) for analog audio, the HA-P50 takes input from non-digital audio players and passes it through its sophisticated amplifier circuits, letting you enjoy a high quality headphone listening environment wherever you are. 
* A combined optical digital input and analog AUDIO IN terminal that self-detects incoming signals.

Compact and robust full aluminum body

Constructed from durable aluminium, the HA-P50's compact, flat body measures just 21.7mm thick, ideal for mobile environments where toughness, small size and lightness are essential. Designed from the outset for mobile use, its compact aluminium volume knob has just the right torque to allow fine volume adjustment. Raised guards on either side prevent accidental volume changes when the HA-50 is being carried in a pocket or bag, as well as protecting headphone plugs from bumps.

Convenient recharging by USB; 8 hour continuous battery life

The HA-P50 has a built-in 2100mAh Li-ion battery, allowing a maximum of 8 hours of continuous battery life (with digital connections) and the included USB-A type DC cable allows recharging from a computer's USB port. A separately sold TASCAM PS-P515U AC adapter allows rapid recharging from wall/mains power, if required. Thanks to its auto power save function, the unit goes into sleep mode after 30 minutes if it has failed to detect a sound signal, or if there's no headphone jack plugged into the headphone port.
