Monitoring real time reverb while recording on the Tascam dp-02cf. I am using the DP-03sd for this, but this can apply to other effect devices as well. Run an (RCA) cord from the DP-02cf line outs to the two A/B ins on the DP-03sd. Then, run the headphone out from DP03sd (I used the left headphone line/plug on a stereo mini to a split y cord) to the (b) record input on the dp-02cf to monitor processed signal. Use the DP-03sd to set level. Be careful of potential feedback loop if levels are set too high. Record your track as usual and hear the real time reverb.
It won't get recorded
I have the normal effect loop hooked up with an effects processor to handle the recorded tracks.

Yes, the setup you've described for monitoring real-time reverb on your Tascam DP-02CF using the DP-03SD as an external effects processor is a valid method, with proper caution regarding levels to avoid feedback loops.
Here's a breakdown of your approach and some important notes:
Your Setup:
Sending Audio to DP-03SD: You're correctly routing the audio from the DP-02CF's line outputs (RCA) to the DP-03SD's A/B inputs. This sends the unprocessed signal to the DP-03SD.
Using DP-03SD for Processing: You're using the DP-03SD to apply reverb or other effects.
Returning Processed Signal for Monitoring: You're cleverly utilizing the DP-03SD's headphone output, splitting it to a single line/plug, and routing it back to the DP-02CF's (b) record input. This allows you to monitor the processed sound in real-time.
Level Control: You're adjusting the effect level on the DP-03SD.
Caution with Feedback: You are aware of the risk of feedback loops and emphasize being careful with levels.
Important Notes:
Real-time Monitoring Only: As you mentioned, the processed signal is for monitoring only and won't be recorded.
Built-in Reverb vs. External Effects: The DP-02 has its own built-in reverb, but this can't be recorded directly during tracking, only during mixdown. Your method allows real-time monitoring of reverb during recording.
Effect Send/Return: The DP-02 uses a send/return loop for applying effects like reverb. The individual channel's effect send knob controls how much of that track's signal is sent to the effects processor.
Feedback Loops: Feedback occurs when a signal from the output is sent back into the input, causing a positive loop. This can lead to a loud, damaging oscillation. Your caution is well-placed.
Alternative Approach (for Recording Effects):
While your method provides real-time monitoring, if you wish to record the effect, you would need to:
Utilize the DP-02's built-in effects send/return: Send the track to the DP-02's effect send.
Connect an external effects processor to the send/return jacks: The DP-02 may have dedicated effect send and return jacks.
Route the external effects processor's output to a free input on the DP-02: This allows you to record the processed signal on a separate track.
Summary:
Your described setup is a clever way to monitor real-time reverb while recording on the DP-02CF using the DP-03SD. Remember to manage levels carefully to avoid feedback and to utilize the standard effect send/return loop for recording the effect onto your tracks during mixdown or using a separate track for recording the processed signal.
