Cayin Pearl the 30i the 30th Anniversary Tube Amplifier
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 pieces for Right channel. Each channel has its own High Voltage Power Supply and Low Voltage Power Supply.
Power supply of each channel is combined by 800 watts High Voltage Power Supply and 200 watts Low Voltage Power Supply. Total power reaches 2000 watts to guarantee the dynamic and transient response during music playback.
Pearl 30i takes separate Power Supply in different stages to guarantee a stable power to the different stages of the Amplifier and provide an linear Analog Power Supply.
Amplifier Unit and Power Supply Unit take high rigidity of chassis structure with finest vibration damping treatment. You can put the units side by side or up and down. It can help realize the best S/N Ratio and lower the magnetic interface to the Amplifier Unit.
Customized 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.
Pearl 30i is designed on basis of Tungsol KT170 Power Tubes. It outputs 230 watts Power in Ultralinear Mode or 145 watts power in Triode Mode per channel. Designed in Class AB Push-Pull Pearl 30i takes four pieces of powerful KT170 tube per channel.
All tube Integrated with CV4004/12AX7 voltage amplification stage, 6SN7 driver stage, and KT170 output tubes.
Following the design concept of Cayin, Pearl 30i offers two operation modes: Triode and Ultralinear. Change the output mode you will get a different sound signature instantly. Triode Mode is Tendering, Rich in Harmony, and Smooth. Ideal for Vocal and Instrumental Music. Ultralinear Mode has power and extension. Clean with energy. Ideal for music has punch and dynamic and at such mode it offers excellent control ability.
In Pearl 30i we also offered choices of two timbres: Dynamic and Soft, which has been realized by adjusting the operation current of the KT170 Power Tubes.
Output transformers are the most important part of any tube amp. They determine how low the bass will reach and how high the top end goes. Output transformers of Pearl 30i are custom-designed, wound in-house with Z11 Audio-grade silicon steel sheet which guarantees less loss of Signal.
Four pairs of line inputs, one pair of Balance Input, one pair of RCA Pre-In and one pair of XLR Pre-In are located on the rear panel of the amplifier. In our Pearl 30i Integrated Amplifier not only the Single Ended RCA inputs provided but also the XLR Balance Input offering you multiple choices to connect with various of Audio Systems.
Different from other inputs Pre-In offers you a possibility to connect to other Preamplifiers so that you can use the Pearl 30i as a Power Amplifier. Both RCA and XLR Pre-In offered in Pearl 30i Amplifier.
One pair of Sub Output is located on the rear so that if you want to get more Bass you can use the inter-connector to connect with your Subwoofer system.
Speaker terminals for 4 and 8 ohm speakers are located on the rear panel of the Amplifier.
Pearl 30i takes Auto-Bias Design for the KT170 Power Tubes. With auto bias design if you changed the Power Tubes you do not need to adjust the bias manually. Bias can be adjusted automatically and precisely so that all tubes can be matched which can raise the reliability of the Power Tubes and provide an extended lifetime of the Power Tubes.
Anodized aluminum front, fully vented chassis with excellent gorgeous finish, and wood decoration top plates give you a product of art in front of your eyes.
Pearl 30i, same as other products from Cayin, employs Point to Point wiring. The entire circuitry including signal path is painstakingly hand wired with heavy-gauge cable by craftsman.
With programmed MCU Pearl 30i is designed with a variety of protection circuits and power-on timing so that the amplifier works in the best condition: 60s Time Delay during Switch on, Soft Start Circuit and BMI Function.
BMI Function: In order to protect and monitor the operation state of the Power Tubes we have designed the Pearl 30i with Bias Monitoring Indicator. Once bias of Power Tube is abnormal the BMI will react and the amplifier will enter into protection.
High-Precision JRC MUSES 72320V electronic volume controller to provide low noise, low distortion and 106-step linear volume control.
Premium Parts: Alps Potentiometer, JRC MUSES72320V Digital Volume Controller, AudioCapX PPFXS Coupling Capacitors, Nichicon Audio-grade Filter Capacitors, Porcelain Tube Sockets, and Carbon film resistors.
Silver Plated Signal wires have been used in Pearl 30i, which guarantees the stable Signal transfer to lower the Signal attenuation and interference.
Standard with remote control, Pearl 30i can memorize last operation of the unit once switched off. Available front finish: Black.
