  • Summing (or mixing) the output of a sub-chain with a parent chain.
  • Soloing the output of a sub-chain.
  • Muting the output of a sub-chain.


This unit allows you to mix the output of additional sub-chains into any chain at any position. The signal arriving from the left of the Mixer Channel unit is added to a panned and attenuated (or amplified) version of the output of the sub-chain associated with the 'gain' parameter. The following diagram depicts the signal flow of the Mixer Channel unit. Notice how the dB meter taps the signal before the mute choke and gain stage. Also, notice how you can chain multiple Mixer Channel units to create a standard mix bus.


The sub-chain that is mixed with the input signal to create the output signal is accessed by focusing the 'gain' parameter and pressing the S1 button:


In the above example, the incoming triangle wave signal has been added to the output of a sub-chain (containing a Manual Grains unit) which was attenuated -1dB and panned hard to the left.



Control Type Has Sub-chain? Fader Range Fader Scale
Simple Fader no -60dB to +12dB logarithmic gain

Controls the amount of gain applied to the signal coming up from the sub-chain before summing it with the input signal (coming in from the left). When this control is selected, the ER-301 sub-display will also show Solo (S2) and Mute (S3) controls. The solo/mute group is formed from all the Mixer units in the parent chain. So if you had 3 Mixer units in a given chain, pressing solo on one of them will mute the other two and so on.


In the above example, Mixer Channel #2 has been solo'ed so that the sub-chain signals going into Mixer #1 and #3 have been muted.


Control Type Has Sub-chain? Sub-chain Parameters Fader Scale
Gain/Bias yes gain (-10 to 10)

bias (-1 to 1)


This parameter only shows up when the Mixer Channel is inserted into a stereo chain. The pan amount for the left and right channels follows the behavior depicted in the following graph:


In other words, a value of -1 will hard pan to the left, a value of +1 will hard pan to the right, and a value of zero will pan to the center (no attenuation for both channels).
