solid state relays

[kambo]

is there anything i should be aware of solidState relays when used in audio

ie:

look into on resistance and off state leakage,

What kind of "solid state relays"?

The big ones are Triacs. They have a 1.2V drop. This is "nothing" on 120V power, but put them in a speaker line you will hear nothing on soft signals, gross distortion in medium signals. In a line-impedance (not speaker impedance) circuit they may never come on at all.  Or they may leak badly.

i was referring to : link on my first post.

this is from their data sheet :

FEATURES :

2. Controls low-level analog signals
PhotoMOS feature extremely low closedcircuit
offset voltage to enable control of
low-level analog signals without
distortion.
3. High sensitivity and low onresistance
Can control max. 0.13 A load current with
5 mA input current.
Low on-resistance of typ. 25Ω
(AQY210EH).
4. Low-level off state leakage current of max. 1 μA
