What is the input signal level?
Is the input signal DC, a single frequency or is it swept frequencies?
What are the power supply voltages?

The voltage gain of the first opamp is 100k/20k= 5.0. So an input of 1.0V results in an output of 5.0V. It has no input capacitor so it amplifies AC and DC.

-120dB is the reduction of a signal to one part in one million.
-180dB is one part in one billion.
-240dB is one part in one trillion.
Something is seriously wrong with your simulation.

The output transistor has its base grounded. It doesn't have a load so its output is nothing. The peak detector capacitor has a DC voltage that is the peak voltage of the filter circuit.

for simulation purposes I put a switch to simulate the output of the 4017
the input is audio from various sources-TV, stereo, Ipod, radio
should I add a cap in series with the input?
power supply is 5v split supply (see batteries)
I will try the simulation w/ a capacitor on the input.

audioguru

The generator in the simulator should feed swept frequencies from about 100Hz to about 10kHz at about 200mV RMS into the input.
Then the first opamp will have a flat response and the filter will have a peaked response. The output is a DC level that is pulsed by the transistor.

If all 200 LEDs are lighted brightly then their total current will be about 2A to 4A and batteries are not suitable. If the LEDs are dim then many AA Ni-MH rechargeable cells will last for a while.

utilizing 7812 and 7912 (going to run the unit at 12 v not 5v (my bad for simulating w/ 5v battery)
the leds are going to be multiplexed so only 20 leds posiable o be lit at any one time.
will recheck the input generator properties.

audioguru

Of course! Multiplexing reduces the average current and the average brightness. Then many AA rechargeable cells will power it for more than 24 hours with pulsing sounds. The 12V regulators need a minimum input voltage of 15V. A lot of battery cells. The 24V total supply voltage might fry something.

batteries argnt even going to be used in the bigger 10 band eq unit. Only the pocket unit which will use a stereo TILT circuit and 2-lm3916's with 10 smd leds per display.
I need to redo my TINA simulation with proper ps voltages. What should I use for the audio input properties?. just been setting at 5v sinewave

audioguru

The big EQ unit doesn't have many LEDs so its power consumption is very low.

The little pocket unit has many LEDs so its power consumption is high.

I recommended an audio input in the simulator of "swept frequencies from about 100Hz to about 10kHz at about 200mV RMS".
