At , behind every innovation, there's a story. The birth of the ZA3 amplifier is just such a story, centered around our users. After the launch of the V3 amplifier, we gathered innumerable feedback from passionate philes. They expressed a desire for us to develop an even better amplifier based on V3.

SNR≥106dB; THD<0.006%; SINAD: 89dB

Delivers pure sound, initiating a high-definition auditory adventure with unmatched clarity.

More power output to elevate your stereo HiFi system to new heights.

Enabling superior sound and ultra-low distortion across the band with Class-D efficiency.

Easy one-click power management with smooth sync across devices, unifying your system.

Compatible with DIP8 dual op-amps. Roll them to get your preferred sound signature.

Enhanced cooling with larger chassis, whole-body heatsink, and side ventilation with dust covers.

Optimized circuit board layout protects core modules from interference for a purer sound.

Helps to achieve a fine volume tuning to match human ear's auditory characteristics.

1. Addressing Functional Issues 1.1 Left Channel and Mono Setup Problems: Mode Selection: Ensure you've selected the correct mode using the switch on the right side of the ZA3. For stereo sound, the switch should be in the downward position; for mono, it should be upward.

Cable Connections: Double-check all input and output cables for secure connections. Faulty or improperly connected cables can cause sound issues.

Power Supply: Make sure you're using the appropriate power supply for your device.

1.2 Power On/Off Issues: Power Switch Operation: To turn your ZA3 on or off, press and hold the volume knob for 2 seconds. This feature might be different from other devices you've used, so it's important to familiarize yourself with this operation.

2. Enhancing Sound Quality 2.1 Insufficient Power and Sound Output: Volume Adjustment: If the sound is too low, try turning the volume knob clockwise to increase the volume to an appropriate level.

Power Supply and Mode: Understand that the power output varies with different power supplies, speaker impedances, and operating modes. Adjust accordingly to achieve the best sound quality. 2.2 Not Meeting Expectations: Source Quality: For better sound, use high-quality files and avoid compressed formats like MP3, which can sound worse when amplified.

Speaker Placement: Position your speakers at least 30cm away from walls or corners to avoid muddy bass sounds.

Subjective Perception: Remember that quality can be subjective. Experiment with different sources and settings to find what sounds best to you.

3. Overcoming Compatibility Limitations 3.1 Incompatibility with Speakers or System: Check Impedance: Ensure your speakers' impedance is within the 2 to 8 ohm range supported by the ZA3 for optimal performance. 3.2 Lack of Additional Inputs and No Signal Output: Input Options: The ZA3 supports RCA and XLR inputs. It does not have a DAC function, so it won't provide a signal output. Make sure your source is compatible with these inputs. 3.3 Power Adapter Size: Adapter Purpose: The 48V/5A power adapter is designed to meet the higher power requirements of the amplifier, ensuring it delivers its full potential. Its larger size is necessary for this purpose.

Note: The product doesn't support Bluetooth.
