Pricing (from Liberty
Instruments, only).
PS9200KIT-LI:
USD $1750
Attenuators for use with PRAXIS
AudPod (20dB or 40dB, specify), for high SPL testing. Allows ACO mic kit
to serve for both high sensitivity and high SPL testing.
Works with other mics having approximately 150 ohm output
impedance. Stated attenuation value obtained only when driving mic input
of PRAXIS Audpod (3.45k input impedance).
USD $20 each (one set of each provided with
PS9200KIT-LI).
