SE electronics ISIS II 2010 -

The sE Electronics ICIS II was a true tube condenser microphone known for its classic sound and robust construction, featuring a dual-mesh grille, a custom ECC83 valve, and a transformer-balanced output. While the original ICIS was discontinued around 2010, the ICIS II was a later iteration that maintained the all-tube circuitry, offering a sound reminiscent of classic microphones with smoothness and detail, while also being responsive to EQ. Key Features and Characteristics:

• Tube Design:The ICIS II utilizes a full tube circuit, not just for cosmetic purposes, with an ECC83 valve at its core, which is socketed for easy replacement. 
• Frequency Response:It covers the full audio range (20Hz-20kHz) with a gentle low-end roll-off starting around 100Hz and a smooth presence peak around 12kHz. 
• Construction and Finish:The microphone is built with a high-quality finish, using substantial metal and a dual-mesh grille for both electrical screening and physical protection. 
• Sensitivity and SPL:It has a sensitivity of 20mV/Pa and a maximum SPL of 130dB for 0.5% THD at 1000 Hz, which are typical for this type of microphone. 
• Sound Profile:Users describe it as delivering a sound that combines smoothness with detail, without being overly hyped or aggressive. It was praised for its warmth and rich tone, with good high-end sparkle. 
• Connectivity:It features a 3-pin XLR connector, common for professional microphones.
