Which Aux sends have the potential for routing to Time-Based Effects on an analog console?

The potential for routing to Time-Based Effects on an analog console is primarily through Aux Sends. Aux Sends are specifically designed for creating auxiliary outputs from a channel, which can then be used to send audio signal to effects processors such as reverb or delay. This allows a sound engineer to add effects to a mix without affecting the original channel output.

Aux Sends can be configured to send a portion of the channel's signal to a separate effects unit, where time-based effects can then be applied. This setup not only provides flexibility in managing various effects but also allows for independent control over the level of the effect applied to the mix.

Channel strips refer to the individual input channels on a console that handle audio signals but do not inherently route to effects themselves without utilizing the Aux Sends. Main busses and subgroup masters are used for combining signals and routing them to the main output or submixes but do not specifically target effects processing. Therefore, while all these elements play important roles in a mix, Aux Sends are the key path for directing signals to time-based effects in the context of analog mixing consoles.
