Product Description
Parameters:
1. RIAA phono part:
RIAA freq response 20hz-20kHz +/- 0.5dB, S / N ratio> 85dB
THD <0.05%, input sensitivity 3.0mV, gain 40dB
Nominal / max output 300mV / 1.8V
Output impedance 200 ohms, input 47k ohm / 220 pF
2. AUX part:
Input voltage: AC12 ~ 18V
Frequency response: 20 HZ - 20 KHZ
Input sensitivity 300 mv
SNR: 96 db
Total harmonic distortion <3% (1 KHZ)
Power range output: 0.2 W
Output impedance: 100K
Input impedance: 50K

Chassis size:
80×116×28mm

Net weight:
0.24Kg (0.55Kg with package)

Package includes:
1 x preamplifier
1 x power supply
2 x 6J1 tubes

What's more:
It will be better if its GND jack can be really connected to the ground, which can decrease the background noise to a very low level.
For MM turntables, please check whether your MM cartridge is the old version. If so. we suggest you to upgrade it as a new version one will bring much better sound.
Please keep T7 away from devices that can transfer signal like cellphones and routers.
