Seller's description

The Shift Line Twin MkIIIS is the third revision of our tube guitar preamplifier which boasts a characterful sound, universal connectivity, and a compact enclosure. The dynamic range has been expanded to achieve more maximum gain. As a result, it can go from its renowned clean sound into crunch and overdrive without external boosting. The cabinet simulation is based on the Impulse Response Convolution technology, which provides a realistic and detailed sound while preserving the character of the power amp, cabinet and microphone used to record the impulse. The device comes with two impulses recorded from the Fender Twin combo amplifier. The microSD card slot allows users to upload their own cabinet impulses. Connections: IN is the signal source input. THRU is a buffered output for the unprocessed signal split from the IN jack. SEND/RETURN is a series effects loop for external processing. The SEND out can also be used as an additional output. OUT is the main output designed to connect the preamplifier to a power amplifier (RETURN or POWER AMP IN on combo amplifiers, INPUT on power amplifiers). AUX IN is an external audio input (the signal from the AUX IN is only heard through the PHONES output). PHONES is a headphones output. BALANCED OUT is a balanced output. POWER IN is a power supply input. The power requirements are 12V DC 650mA. MicroSD is a microSD card slot. Controls: GAIN controls input signal amplification. It can go from a crystal-clear sound all the way to a classic California-style overdrive. The BASS, MIDDLE and TREBLE knobs constitute a classic 3-band passive EQ with a mild frequency correction effect. MASTER controls the volume of the signal coming from the OUT jack. VOLUME controls the volume of the signal coming from the PHONES and BALANCED OUT jacks. The MASTER and VOLUME knobs work independently. The TOP switch controls the signal's high frequency harmonic content. The "+" position accentuates the highs and the attack. The "-" posi
