■ Tube preamplifier / direct box
■ Input: Phone
Output: TRS phone, XLR balance (2nd HOT), headphone
■ Vacuum tube: 12AX7A / ECC83 used
■ Circuit form: High voltage class A
■ GAIN: 6dB step with switch, MAX GAIN + 24dB
The gain that boosts low-powered instruments corresponds to various levels of equipment, and produces a variety of tones. In addition, it uses a click-type pot, so it is easy to remember the settings.

■ Maximum input level: Unbalanced + 23dBu
■ Maximum output level: TRS: + 21dBu, XLR: + 2dBu
■ Frequency characteristics: 20Hz-100kHz -1dB
Power supply: Internal AC supply
■ Dimensions and weight: 215.9W × 44.4H × 215.9Dmm, 2.27kg

[Front Direct Out]
Outputs the signal input to INPUT as it is.
[Ground lift]
Noise from ground loops can sometimes be reduced.
[LOADING]
This is used to adjust the impedance of the signal input to INPUT between 10kΩ and 2MΩ to match the impedance of the instrument to the TD100. Use it as a kind of tone control and set it to the sound you want.
[Headphones Out]
The volume is controlled by the output gain and the volume of the instrument.
[TRS phone line level OUTPUT]
Used when connecting to recording equipment without using a preamplifier
[XLR / MIC level / OUTPUT]
Used when connecting to equipment equipped with a preamp such as a mixer

~ Quick Start ~
① Connect instrument to INPUT
② Connect TRS phone or XLR output on rear panel to recording equipment
③ Adjust OUTPUT gain to optimal level
④ Adjust to the best sound with LOADING on the front panel
⑤ After that, just play!!
