FM30 vacuum tube tube amp headphone amplifier Frequency response: 26-38KHz 2db
Product parameters:
Input: one RCA input
Output: The output impedance of the rear power amplifier interface is 4 ohms, 8 ohms, two groups of interfaces 4w+4w
Front 6.35mm standard headphone output hole 19-600 Euro
·Frequency response: 26-38KHz+2db
Output Signal to Noise: >118dB ''A''-wtd
Output THD: <0.008% 10Hz to 20kHz
·Amp output peak: (about 1w) (Please correspond to the headphone impedance meter for the corresponding power
Calculate)
Features
The signal source may be a CD player and a computer audio source (there must be a cable on the computer sound card
output port)
1. Use all AC filaments to light the lights, listen to them with 102DB headphones, and hear nothing
Spot the hum noise, it feels as quiet as no boot
1 Adopt fM30 parallel class A amplifier circuit driven by 6n2, output 4w+4w power
Amplifying and promoting the speaker requires a two-way speaker with an impedance of .4-8 ohms, a sensitivity of more than 6.5 inches above 90db, and a headset of 19-600 ohms (about 1w).
3 The volume potentiometer adopts Taiwan-funded A100k fully sealed potentiometer to ensure clear positioning and left and right balance
4 Using metal film resistors with an accuracy of up to 1%
5 Adopt 0.8mm brushed stainless steel with wooden chassis structure,
