Default Symetrix Compressor limitors for sale

Need to sell some stuff for some out of town $$$

I have 2 Symetrix Compressor limitors for sale.

Symetrix 421M
The Symetrix 421m is a single channel automatic gain controller with noise reducing downward expander, peak limiter and selectable `speech curve` filters. Input may be from mic or line. Use the 421m to increase intelligibility in public address and paging systems or in any application where constant audio levels are desirable.
The 421m AGC-LEVELER is a sophisticated audio gain controller, but what it does is simple: it makes quiet sounds louder and loud sounds quieter. Set the `target` output level and the 421m gently boosts signals that drop below your target, and smoothly pulls back those that rise above it. Operation is automatic, precise, and transparent.

Target oriented AGC-leveler
Final stage limiter
Downward expander with audio threshold
Line and mic inputs
125 Hz and 6 kHz speech curve filters
Parallel input and output metering
Stereo linkable

Asking $75.00

Symetrix 525 Dual Gated Compressor/Limiter
Description: The 525 Gated Compressor/Limiter utilizes Symetrix` program-controlled interactive dynamic range processing technique,
which combines the best attributes of both compressor/limiters and expander/gates.

Asking $50.00

I need to sell these this weekend if possible! Paypal only please!
