Best way to mix 6 separate audio processors into a single stereo track

Hi, Ive been perusing the docs but Im still wondering whats the best way to approach mixing 6 separate audio processors into a single stereo output?

Each of the 6 channels is part of an audio chain which will has a pan and level control, following this will be another audio processor which will be acting on the mixed single stereo doing some eq and sound shaping. I feel like Ive got a solid handle on everything but the mixing of the 6 separate audio processors?

Is it as it as simple as using the MixerAudioSource and adding the 6 audio processor outputs that have has the pan and level set as you want them?

Or perhaps use a AudioProcessorGraph to connect the 6 processors together to the processor doing the eq and sound shaping?
