Headphone impedance
You may have several headphone of different impedance. The
impedance commonly in the market is 16
Ω
, 32
Ω
and some may over
hundred. Our THA-21 caters for different headphone impedance to
provide best performance. You may select the impedance setting from
rear panel
; "L" for 16~30
Ω,
"M" for 32~90
Ω and
"H" for 100~300
Ω.
Cascade to following amplifier stage
If you wish to make use of the THA-21 Vacuum tube pre-amplifier stage
for your other amplifier. You may use THA-21 output
as tube
amplifier stage for following amplifier stage to your other instrument.
