All items ONE-YEAR WARRANTY !!!
We can Declare the Value of the Order as Customer's Remark!!!
the price is for a pair
The sound of PSM-300T is based on the upgrade of PSM-300. The main point is to add the 6N16 tube and add the working status indicator.
The audio signal input stage is a 6N16 tube for gallbladder field hybrid differential voltage amplification, the famous transistor is used for the second stage and then differential voltage amplification. The final stage consists of 24 high-power transistors to form a powerful power output stage, which easily pushes large to 2 ohm impedance. Speaker.
It can set the output status of Class A or Class A, which is convenient for the adjustment of the tone. It can also save the power consumption and greatly reduce the heat of the chassis, so that you can choose the appropriate working mode when listening to different music content.
The panel is provided with a working status indicator table, which enables the user to clearly observe the running state of the machine in Class A or Class A and B, with stylish dynamics and appreciation.
The design is based on the main purpose of the product, the details are rich and elegant, each detail is derived from the inside out, from the big to the small, naturally wonderful and nothing to do.
The whole machine is black in large area and decorated with a small amount of aluminum metal natural parts, which not only enhances the visual impact, but also makes the black have different charms. The relationship between stability and vitality, the whole and the details is very wonderful, wonderful and very Look good, highlighting the luxury temperament.
The Sound PSM-300T is a post-stage mono gallstone hybrid DC power amplifier with a unique gallstone DC mono balanced amplification design. It consists of 24 high-power transistors and a powerful power output stage with a drive impedance as low as 2Ω. The huge driving force of the "food" speaker.
Independent mono balanced transmission amplifier structure.
The audio signal input stage is made up of 6N16 electron tube for gallstone mixed differential voltage amplification, and the famous transistor is used for second stage re-differential voltage amplification;
The final stage consists of 24 powerful power output stages.
The power supply part consists of a 1500W toroidal transformer and 120,000 microfarad audio dedicated electrolytic capacitors.
With a working status indicator, it is clearly observed that the machine is in Class A or Class A and B.
