The SPL PASSEQ Passive Mastering Equalizer is designed for professional audio applications.

The SPL PASSEQ Passive Mastering Equalizer is designed for professional audio applications. It features a passive equalizer with 144 total filters. The unit has a maximum input level of +32.5 dBu and an impedance of 20 kOhms, balanced. The maximum output level is also +32.5 dBu with an output impedance of < 600 Ohms, balanced. Noise levels are -91.8 dBu (unweighted), -95.2 dBu (A-weighted), and -86.2 dBu (CCIR). Common mode rejection is -60 dBu at 1 kHz.

THD & noise exceed 102 dB. The transmission bandwidth ranges from 10 Hz to 200 kHz with a -3 dB drop. Frequency range extends up to 35 kHz. Power consumption is 0.06 A at 230 VAC / 50 Hz, 9.5 W, 13.6 VA, or 0.09 A at 115 VAC / 60 Hz, 9.5 W, 13.6 VA. Fuses are 0.5 A for 230 V / 50 Hz and 1 A for 115 V / 60 Hz. Dimensions are 19 x 7 x 12.3" (4 RU).
