Plugging In Stereo Headphones
The headphone amp can only work with stereo headphones fi ed with a 1/8" (3.5 mm) TRS
jack plug. Headphones with impedance ranging from 16 to 64 Ohms are acceptable. In the case
of stereo headphones with a different plug, a proper adapter shall be used. Headphones and
adapters shall be purchased separately. One shall not use mono (TS jack) headphones or
headphones with an embedded microphone with a 1/8" (3.5 mm) jack with this instrument.
OMTP, CTIA, or similar TRRS jack plugs are also not usable with this bass.
Although a stereo headphone amp is a part of the instrument, one shall note that the bass
guitar is not a stereophonic instrument. For that reason, both channels of the headphones (le
and right) transmit the very same, monophonic pickup signal that is only split between the two
channels of the headphone amp.
