Q: Is volume control available in Bypass Mode?
A: No, in Bypass Mode, both volume and tone control are unavailable. The amplifier's volume is set to maximum by default. Please lower the source volume before switching to this mode to prevent hearing damage and speaker damage.

Q: What should I use the 12V trigger input for?
A: The 12V trigger input is for preamps or DACs with a trigger output to sync power on/off. Please do not use it as an audio input or connect to a power supply.

Q: Are there any specific requirements for the speakers connected to the A and B channels?
A: It is recommended to use speakers of 4-8Ω with matching impedance for each channel. For example, use two 4Ω speakers for channel A output and two 8Ω speakers for channel B output.

Q: Does the remote control include batteries?
A: For safer and faster delivery, the remote control may not include batteries (AAA*2). Please prepare the batteries yourself.

Q: Can the brightness and color of the VU meter be adjusted?
A: No, the brightness and color of the VU meter are fixed and cannot be adjusted.
