ANALOG SQUARED PAPER TUR-08

Brand: Analog Squared Paper

Product Code: ANALOG SQUARED PAPER TUR-08

฿95,400

TUR08 has the power to sufficiently drive low-efficiency headphones such as flat drive and open air, Inherited the Clarity of the TUR series and the dynamic feeling of the tubes.
The internal is composed of a tube preamplifier section isolated from electromagnetic field noise and a powerful buffer amplifier section of eight power transistors.
It is designed to bring out the ideal characteristics of parts and headphones by adjusting the operating range of the tube checking the Level meter and continuously changing the gain level.


SUMALLY

● 1U4 Direct heated tube family used for amplification.

● Strong buffers support both single output and BTL.

● Strong driving and braking by quad amplifier.

● Non over all feedback amplifier.

● LR independent power supply and capacitors.

● High Quality original power supply technology.

● Low noise design by independent adjustment level of tube pre and Buffer.

● Level meters that capture suite points of vacuum tubes.

● Battery check function with meter.

※Unbalanced input is basic. 
Balance input is Exclusive and optional.
