Adjusts the left-to-right channel volume ratio.
Connect your speaker cables to the binding posts on the rear. Ensure the positive (+) and negative (-) terminals match your speakers perfectly to avoid phase cancellation.
Ensure no stray wire strands cross over to touch the chassis, which could cause a short circuit. Source Inputs jadis da30 manual
The DA30’s VU meters are driven by the output signal. If they are stuck, the meter driver board may have cold solder joints. Solution: This is not covered in the manual. Resoldering the small PCB near the meters usually fixes it.
Match the numbers marked on the tube boxes to the corresponding socket indicators on the chassis.
starts with its raw data. It is a Class A integrated amplifier designed for purity and musicality. 30W RMS per channel. Tube Complement: Power Tubes: 4 x 6550/KT88/KT90. Preamp/Drivers: 3 x ECC82/12AU7 and 2 x ECC83/12AX7. Sensitivity: 115 mV.
Use a clean cloth or wear gloves to handle the tubes; skin oils can bake onto the glass and cause premature tube failure. 3. Rear Panel Connections [Left Speaker] [Right Speaker] + - - +

Like all high-performance audio equipment, the DA30 benefits from periodic maintenance. The most common tasks involve tube replacement and fuse checks.
A failing power or driver tube can introduce a severe hum. Try swapping the left-channel and right-channel driver tubes to see if the hum moves to the other speaker. 2. Loss of Volume or Soft Distortion in One Channel This is a classic symptom of a weakening tube.
Ensure the DA30 volume control is turned completely down (fully counter-clockwise).
