Operation
This section describes how to operate the Jasmine LP3.0MK1
Phono Pre‐Amplifier.
MM or MC mode setting
Please set the correct running mode according to the phono
cartridge type which you are using by the Cartridge type
switch on the front panel.
For some high output MC cartridges, it need 47K Ω load
impedance. In this situation. Please select MM running model.
In MM model, the impedance of Jasmine LP3.0MK1 is
fixed at 47K Ω.
Setting Load Impedance
The load impedance switch is only available for MC running
model.
Please refer to your cartridge parameters to choose a right
impedance value by Load Impedance switch on the front
panel. The load impedance have to be greater than 5 times
of the internal resistance value of the cartridge at least.
Inappropriate load impedance value will cause a distorted
sound.
Setting Gains
Jasmine LP3.0MK1 supplied two gains mode, Low and High,
Low:
RCA Output
：
MM=40dB, MC=60dB
XLR Output
：
MM=45dB, MC=65dB
High:
RCA Output
：
MM=45dB, MC=65dB
XLR Output
：
MM=50dB, MC=70dB
You could select an apposite gain mode according to your needs.
Before you turn the Gains switch, please turn the volume switch
of your amplifier to minimum, or change the input to another
channel, to avoid the bang bang noise from speakers.
