DBX Compressor Limiter

I got a dbx 166xl compressor limiter for sale
its 9/10 condition
its going for 19000 neg
Features

• Goof proof operation to smooth uneven levels, add sustain to guitars, fatten drums or tighten up mixes
• New gate timing algorithms ensure the smoothest release characteristics
• Program-adaptive expander/gates
• Great sounding dynamics control for any type of program material
• Separate precision LED displays for gain reduction, compression threshold and gate threshold allow quick, accurate setup
• Stereo or dual-mode operation
• Balanced inputs and outputs on 1/4" TRS and XLR
• Side Chain insert
• Classic dbx® "Auto" mode
