Triple Output, Triple Sound

KANN ULTRA features a Triple Output Mode that allows you to enjoy Astell&Kern's perfectly prepared sound when connected to demanding headphones, highly detailed IEMs, and external devices.

Instead of simply separating the output ports, Astell&Kern's Teraton Alpha technology allows for separate amplifier/sound design for the Headphone Out and Line/Pre-Out ports to provide the optimal sound for each port.

Complete your powerful Head-Fi system even on portable devices with the KANN ULTRA with Triple Output.

1. HEADPHONE OUT

The port features 4 preset gain settings and ultra-high output of up to 16Vrms. The headphone port is designed to perfectly run demanding headphones with high impedance using only the player with no external AMP.

2. PRE-OUT

Select Pre-Out mode on the Pre/Line Out port to output sound to an external amplifier or audio device.

[ Pre-out ]

This mode delivers sound through a specially designed Pre out amplifier, instead of the high-powered Headphone out amp.

Pre-Out functions like a PRE AMP and you can control the volume with the volume wheel.

* No Gain or Voltage settings, maximum output 2Vrms/4Vrms

3. LINE OUT

Select Line Out mode on the Pre/Line Out port to output sound that is optimized when connected to external devices.

[ Line out ]

This mode outputs the sound from the DAC directly without going through an amplifier, resulting in the lowest noise level and making it ideal for connecting to external audio devices.

Line Out has a fixed voltage output (4 levels) and no volume control.

* Do not activate the Line Out mode while earphones or headphones are connected to the PRE·LINE OUT port. Doing so may cause permanent hearing loss.
