Portable Amplifier for High-Performance Headphones

The HA-P50 is the ideal headphone amplifier for the audiophile on the go, and it allows you to take that great Reference 501-grade headphone listening experience outdoors and enjoy it wherever you want to go. Packs a high-performance digital-to-analog adapter and high specification power amplifier circuit into a compact body to bring out the very best from quality headphones.

High-Quality Sound From iPhone or Android via USB Digital Input

Digital audio signals stored in your iOS device or Android are extracted digitally via USB and processed through the HA-50's high-performance built-in digital-to-analog converter, with minimal sound degradation and allowing the purest playback quality, with maximum fidelity. The HA-P50 can be used with the free TEAC HR Audio Player app for high-resolution 24bit/96kHz audio playback for iPhones and other iOS-based devices... there's no need to buy a separate adapter (such as the Apple camera connection kit) in order to connect. It also comes with rubber fixing straps for securing it to an iPhone or Android handset, making the HA-P50 very easy to carry around.

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

Fitted with a 160mW + 160mW high-output power amplifier (at 32 ohms load), this amp lets you drive 600 ohm-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 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, and it is 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 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.

Compact and Robust Full Aluminum Body

Constructed from durable aluminum, 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 aluminum 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 via 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.
