-
All wires are connected. Why is there no sound output?
1.Check if the circuit connection is correct and if the machine has started and switched to the corresponding input channel.
2.Ensure volume is not set too low; adjust if necessary.
3.Confirm audio source is not paused or muted.
-
Why does sound distortion occur?
Excessive input volume may cause distortion when both source and unit are at maximum levels. Reduce either volume to resolve.
-
Why doesn't the AlYIMA T20 Balanced preamp have bass and treble controls?
While tone controls are common in entry-level preamps, the T20 eliminates them for a cleaner signal path, lower noise, and uncompromised fidelity. This focuses performance on its advanced core circuitry, maintaining a true purist design.
-
Why does the digital display have a 20-second countdown upon startup?
The purpose is to protect the vacuum tube and extend their lifespan.The 12AX7 tube is a key amplification component.It requires a preheated cathode to emit electrons properly.Applying high voltage to a cold cathode causes stress and accelerates aging
-
What's the difference in sound between the T20 and traditional tube preamps?
The T20 employs a combination of ECC83 (12AX7) vacuum tubes and LME49720 operational amplifier chips. The resulting overall sound quality is particularly evident in the midrange, low frequencies, and high frequencies
