LM1876 arduino mute

hey guys

i am waiting for my arduino MEGA to arrive in a few days.

i need to switch a bunch of LM1876's op amps on/off. they have mute pins that mute the signals passing through by receiving 2.5v.

so i figured i could use the arduino pins to switch an array of amps on/off.

however, my question is - do i need to put some kind of resistors inbetween or something to avoid drawing too much power/frying my arduino while muting 10+ LM1876's??

i should add, by default ALL AMPS WOULD BE MUTED AT THE SAME TIME - meaning id continuously be sending 5v through at least 10+ pins most of the time.

also, another question - i have never tried the LM1876's mute function - its instantaneous, right? im building a musical instrument, so if the mute function is delayed, its useless.

thanks!
