Default Tone Control Stereo with preamp in bpa200

HI everyone,

Recently I build bpa200, and I'm satisfied with the performance.
but I want to make my project more functionality, that's why I bought stereo tone controller,

my question is:
it is OK if I connect the tone controller to my DIY amplifier without over-driving my DIY amplifier?

here the specification of tone controller:
the opamp is an6551.
Freq, range: 18hz to 18khz less than 1 dB
tone control: bass _15 dB at 40Hz - treb _ 15 dB at 16Khz
Total Harmonic Distorton: (THD) better than 0.05% at +=1khz/ v-out ivrms
input sensitivity: tuner, tape deck and other 200m vrms
output impedance: 60 ohms
s/n radio : better than 55 dB at any vol. setting / all flat

Please attach your pictures to the forum using the Mange Attachments tool under the Go Advanced tab.

This way we will be able to see them and they won't later get lost when your picture's dropbox or whatever you use goes defunct years later.
