LP1, Ultra-low Noise Linear Power Supply
2. Power Consumption: < 45W
3. Power Output Noise Floor: < 20μVrms
4. Modular Rectification and Voltage Regulation Design
5. CNC Machining
6. High Performance & Ultra-low Noise
Ultra-low Noise Linear Power Supply
Customized HIFI Toroidal Transformer
Rectification and voltage regulation are designed into two modules, three independent rectification outputs. Reduce the mutual interference between the outputs and effectively reduce the noise floor.
CNC Machining
CNC machined from a solid block of aluminium, continuing the minimalist design of the QXD1 and QXA1. The surface anodizing process brings a very delicate touch.
After the LP1 is powered on, all indicators will light up and then go out to complete the self-checking process.

3. AC power input connector: Please use our customized three-phase power cable to get the best playback quality | |
4. Voltage selector switch: Please check the correct voltage before using LP1 and the wrong voltage will damage it • 110V for AC 100 ~ 120V @50/60Hz • 220V for AC 220 ~ 240V @50/60Hz | |
5. 5V2 output: 1.5 ~ 2A | 6. 5V1 output: 1.5 ~ 2A |
7. 12/15V output: 1A | |
Note:
1. Long press the "SET" button for 3 seconds, the indicator light will flash, outputs will be turned off after 1 hour; Continue to press and hold for 3 seconds, the indicator light flashes slowly, and outputs turns off after 2 hours.
2. Press the "SET"button once can cancel the timing output off setting and eliminate the flashing state of the corresponding indicator when the current isoverloaded (If there is no other operation after eliminating the warning state,the indicator light will continue to flash after 3 seconds).

FAQs
Q1: Can the three power outputs work at the same time?A1: Yes
Q2: How to switch between 12V and 15V output?
A2: Press the "12V/15V" button once and the output is turned on, then long press the button for 3 seconds to switch, while the warm white indicator light on is 15V output; the cool white indicator light on is 12V output.
Q3: What is the maximum output current of 5V USB?
A3: 5V1+5V2=3A
Q4: Does LP1 have a memory function?
A4: Yes The last state(on/off) of all outputs will be memorized after power off.
Q5: How to cancel the timing off output?
A5: Press the "SET" button once or power off.
Q6: Why does the output indicator light suddenly flash?
A6: When the current is overloaded,the corresponding output indicator will flash, and this output will be turned off after three seconds.
Q7: Can the outputs be set with a timer for automatic shutoff?
A7: Yes. Long press the "SET" key for 3 seconds; the indicator flashes, and the output will turn off after 1 hour. Continue long pressing for another 3 seconds; the indicator flashes slowly, and the output will turn off after 2 hours.
Q8: What voltage regulator chips does the LPI use?
A8: TPS7A4700 * 5.
Q7: Can the outputs be set with a timer for automatic shutoff?
