The remaining switch is called the Output Impedance switch. This is usually the last switch you should

adjust, because the already huge diﬀerence in sound it makes will be even larger after you have the

previous switches set to your liking.

This switch, located here, is labeled “HiZ” and “LoZ” , short for High Impedance and Low Impedance with

regard to the type of headphones you have connected to it. Typically phones that are rated at 50 ohms

or less are considered Low Impedance, while everything else all the way up to 600 ohms is considered

High Impedance. The ZH-1 will driver headphones from 30 ohms to 600 ohms in the HiZ setting and

headphones from 10 ohms to 600 ohms in the LoZ setting. Because of this high overlap between the

two settings it is likely youʼll be able to use both. Choose the one that sounds best to your ears.

NOTE: In “HiZ” mode the output stage of the ZH-1 is direct coupled to the headphones and will sound

more accurate and dry. In “LoZ” mode, the output stage is capacitor coupled to the headphones and will

sound more juicy and spacious.
