Passive headphone impedance matcher produced by Shanghai Laoye. Originally equipped with a 50 cm long single crystal copper cable, one end is a 6.5 headphone plug, and the other end is a Neutrik four-core male plug. There are two hand-wound output transformers inside the machine, and the internal wiring and the enameled wire of the transformer are all 5N purity OCC single crystal copper(The internal wiring of the special single crystal silver version is single crystal silver). The transformer silicon steel sheet is a 0.35mm product from Kawasaki, Japan.
The adapter itself has a Neutrik four-core input, as well as a 6.5 headphone output, a four-core balanced headphone output, and a dual three-core balanced headphone output. All sockets are imported original Neutrik products.
usage:
1. When connecting a transistor amp, the left input lever should be in the L position. When connecting to an OTL tube amplifier amp, the left input lever should be in the H position.
2. Whether the lever H or L on the right depends on the earphones inserted. Headphones above 300 ohms should be in the H position, and 30-60 ohm low-impedance headphones should be in the L position. It is recommended to listen to the earphones with a medium impedance of about 100 ohms.
Three recommended usages:
1. The 3.5mm headphone output of the mobile phone is converted to 6.5 through the conversion head and then connected to the adapter, and high-impedance headphones such as HD800 and T1 are pushed in the H output file. The effect is surprisingly full and thick, which is a world of difference from the direct push of the mobile phone. The connection method is shown in Figure 2 of the title.
2. OTL type tube amplifier amp, after connecting the adapter, push the low-impedance earphone in the L position. OTL tube amplifier amps are inherently not suitable for low-impedance earphones. Generally, they are not full, but through the adapter, a very full and thick effect can be obtained.
3. Connected to the speaker output end of the power amplifier, used to drive headphones such as K1000 and HE6 that are particularly difficult to push.
