1. Introduction Safety Guidelines Thank you for your purchase of Miu-Audio MKTP-2 Class-T stereo Headamp, Preamp and power amplifier. Important safety instructions Miu-Audio introduces the mini-size Class-T stereo amplifier MKTP-2 providing up to 2x15W output with the bundled AC power supply unit.
7 Climate The equipment has been designed for use in moderate climates and in domestic situations. 8. Cleaning Unplug the unit from the mains supply before cleaning. The case should normally only require a wipe with a soft, lint-free cloth. Do not use chemical solvents for cleaning. We do not advise the use of furniture cleaning sprays or polishes as they can cause indelible white marks. 9.
3. Overview 1. Volume Controller and Pre-Amp Power On/Off. 2. 3.5mm Headphone socket 3. Power Indicator WARNING: When plug in your headphone or MP3 into the mini jack (2), always plug in a vertical way. NEVER shake the mini jack as this will permanently damage the internal structure of the socket causing bad contact of signal. -7- 4. Audio signal line output. 5. Audio input. The audio signal input (LEFT/RIGHT) connects from audio source (e.g. CD player) to the amplifier by the RCA audio cable. 6.
3.1 Connection 4. Specifications The mini series is easy to use product.

4.3 Specification of the Pre Amplifier Unit 5. Technical Notes (for professional user only) Vacuum Tube Miu-Audio has already pre-set the jumpers and fine-tuned the DC bias voltage of each MKTP-2 with the packaged vacuum tube before shipping. However, changing different tubes to taste for different sound is the great fun for many audiophiles and also a great feature of MKTP-2. Signal-to-Noise Ratio (SNR) THD + Noise Input Audio 6DJ8/6922 series or 12AU7 series (exchangeable) 92dB 0.05% @ 10k ohm 0.
6. Troubleshooting 5.1 DC Bias Voltage Tuning Since each tube might derivate a bit in parameters, especially from different series, it needs to re-tune the DC bias voltages to guarantee the machine is working in the best point and performing the best sound quality. There are two blue precise adjustable potentiometers (P1, P2) for tuning the DC bias voltage of each channel. The DC bias has been tuned in factory.
