This is the Focusrite ISA Two, a classic 2-channel microphone preamplifier. I am selling it due to a change in studio equipment. **Usage Environment and Condition:** * **Purchased from:** Soundhouse, brand new. * **Storage:** Used for approximately 10 years, mounted in a recording studio rack since its introduction. It has been used in a completely smoke-free and pet-free environment. * **Usage Frequency:** Channel 1 was used for recording and streaming, but Channel 2 has never been used and is in unused condition. * **Maintenance:** All terminals and contacts have been polished and cleaned prior to listing. **Appearance:** Due to long-term rack mounting, there are some scratches as follows: * Photo 6: Scratches on the top panel. * Photos 7-8: Paint peeling and scratches on the rack ears (near the screw holes). There is no damage that affects the operation, and the front panel is in relatively good condition. Please check the photos for the exterior condition and purchase with your understanding. **Included Accessories:** * Main unit * Power cable (3-pin, with ground wire) * Bonus: 1 short microphone cable (CANARE cable + NEUTRIK connector) * Very convenient length for patching within a rack. **Operation Check:** Input/output of Channel 1 and the operation of each switch have been confirmed. You can immediately use the clear and full ISA sound provided by the traditional Lundahl transformer. As it is precision equipment, it will be carefully packed with bubble wrap and cardboard and shipped via Mercari's insured shipping service. Instant purchase is OK. Thank you. \#Focusrite \#ISATwo \#MicrophonePreamplifier \#DTM \#Recording \#HomeRecording \#PAEquipment
