Dual Headphone Output Ports Supporting Both Single-Ended & Balanced Headphones
DD HiFi TC44C features two headphone output ports, one single-ended 3.5mm and another 4.4mm balanced port. Users can use their favorite IEMs/Headphones with the TC44C with their preferred termination option(Single-Ended or Balanced). Both of these ports, despite being different in size are aligned in a straight line providing an excellent aesthetic look with the device.
OCC Copper Internal Wiring
The circuit design of TC44C simplifies the internal wiring by separating the 4.4mm socket with multiple connection pins from the mainboard. For this, all the internal connections are done using high-purity OCC Copper wires. The soldering here is done using lead-free soldering tin with 3% silver.
If you follow DD HiFi products, you must be aware of their excellent craftsmanship. All their connectors and adapters have absolutely brilliant build quality, top-notch to put their build-in simple terms. The latest TC44C is no different here, it adopts their latest green and golden color combination with a full metallic build.
Multi-Color LED Indicator
The 4.4mm headphone output port on the DD HiFi TC44C is transparent. It has a multi-color led indicator built into it that glows into different colors depending on the active bitrate of the signal. Blue light here indicates PCM output, Green indicated DSD decoding. Do note that, when something is connected to this 4.4mm port, the LED light won’t be visible.
