Details

Controls: Low freq boost (4 freqs, 0 to +14 dB) / attenuation (0 to -18 dB); High freq boost (10 freqs, variable Q, 0 to +18 dB / +10 dB) / attenuation (3 freqs, 0 to -18 dB)

I/O: Balanced, fully floating XLR-equivalent I/O via RM frame connectors, transformer-coupled

Notable use: Circuit equivalent to the PE 1C / classic Pultec EQP-1A, packaged as a modular unit

Notes: FLAG: this is Tube-Tech's proprietary 'Modular RM Series' format, NOT industry-standard API 500-series - it requires a dedicated Tube-Tech RM power/rack frame and is not interchangeable with standard 500-series lunchboxes. No standalone rack_units or price published on tube-tech.com; not found at major US retailers, so price_usd left blank per no-guessing rule.
