Signature 12 MTK is a 12-channel analog mixer. Price has been finalized. It is also listed on platforms like PayPay Flea Market, so it will end when it sells. The price may vary considerably depending on the sales platform. While the Signature 12 without MTK is sometimes seen used, this MTK model is a rare find. The difference from the standard Signature 12 is the USB audio interface function, which allows multi-track recording of each mixer channel to a PC. The mixer's configuration is luxurious, with a focus on sound quality, as the name Signature suggests. The microphone preamps feature the Soundcraft Ghost microphone preamps, the high-end console, built-in effects are Lexicon Pro, and channels 1 and 2 have DBX limiters. Built-in mixer effects are usually just a bonus, mainly reverb, but this model has 22 different effects, including tape delay, lo-fi, and tremolo, suitable for dub. There are also two knobs to change the effect parameters, allowing for a wide range of sound creation. There is a problem with only ch3; recording itself is possible, but the para-out to ch3 is not working. (Channels 1, 2, and 4-12 are all working fine.) Therefore, the eq, fader, and FX of ch3 cannot be used (even if the out is set to something other than ch3). Other than ch3, operation has been confirmed. Everything included is shown in the photos. Please judge the condition from the photos. 100V only. Hivino PSE sticker attached. Thank you.
