      FAQs

      How many Sparkos SS3602 op-amps do I need for the ZD3?


      For RCA output, replace one op-amp. For XLR balanced output, replace two op-amps corresponding to the left and right channels.

      How to replace the op-amps?

      Tools required: needle-nose pliers, tweezers, and an H2.0 hex screwdriver.

      1.Use the hex screwdriver to remove the two screws on either side of the rear panel.

      2.Remove the front panel knob, and with needle-nose pliers, unscrew the nut and washer from the potentiometer, then slide out the front panel.

      3.Disconnect the components near the notch of the circuit board by the front panel, which is connected to the Bypass mode switch.

      4.Carefully pull out the mainboard, and you will find three interchangeable op-amp chips.

      5.Replace one op-amp for RCA output and two for XLR output, corresponding to the left and right channels.

      6.Use tweezers to gently pry out the op-amp chip(s) from the side pin gap.

      7.Install the new op-amp chip(s) into the sockets. Ensure correct orientation by matching the '1' marking or the groove on the chip cover with the 'O1' position on the PCB. Incorrect installation may damage the op-amp.

      8.After installing the new op-amp(s), connect the amplifier, power, and speakers to test if the sound is working. If all is fine, reassemble the device.

      Can I get a video on op-amp swapping for the ZD3 DAC/Preamp?

      Please refer to the tutorial video for guidance on swapping op-amps: Watch Video.

      Can I use the Trigger Out from the ZD3 to control two ZA3 amplifiers?

      Yes, you can use a dual 3.5mm male splitter cable to control two ZA3 amplifiers synchronously.
