ℹ Product Information
Separate and Independent Power Supply System
Pearl 30i the 30th Anniversary Tube Amplifier is an Integrated Amplifier in two cabinets with separate Amplifier Unit and Power Supply Unit. In the Power Supply Unit it is combined by four pieces of Power Transformers, which are two pieces for the left channel and two for the right channel. Each channel has its own high voltage power supply and low voltage power supply.
The power supply of each channel is combined by 800 watts high voltage power supply and 200 watts low power supply. Total power reaches 2000 watts to guarantee the dynamic and transient response during music playback.
Amplifier unit and power supply unit take high rigidity of chassis structure with the finest vibration damping treatment. You can put the units side by side or up and down. It can help realise the best S/N ration and lower the magnetic interface to the amplifier unit
Customised power cables
Customised power cables between the amplifier unit and power supply unit. Left and right channel take four cables made out of 6N Copper silver plated wire.
Tung-Sol KT170
The Pearl 30i is designed on the basis of the Tung-Sol KT170 power tubes. It outputs 230 watts power in ultra linear mode or 145 watts power in triode mode per channel. Designed in Class AB push-pull, the Pearl 30i takes four pieces of powerful Tung-Sol KT170 tubes per channel
Dynamic Auto Bias
Pearl 30i takes auto-bias design for the KT170 power tubes. With this design, if you changed the power tubes you would not need to adjust the bias manually. Bias can be adjusted automatically and precisely so that all tubes can be matched raising the reliability of the power tubes and providing an extended lifetime of the power tubes.
Dual-Operation Mode: Triode / Ultralinear
The Pearl 30i offers two operation modes: triode and ultralinear. Change the output mode and get a different sound signature instantly.
Triode Mode: tendering, rich in harmony, and smooth. Ideal for vocal and instrumental music
Ultralinear mode: has power and extension. Clean with energy. Ideal for music with punch and dynamic offering excellent control ability.
Dual Timbres: Dynamic / Soft
This has been realised by adjusting the operation current of KT170 power tubes
