Thanks SO MUCH, ST! It’s all working well right now.
I appreciate all of your help!!
PS; does quality of the cable affect volume output?
Unless the cable is defective, the quality of the cable is not likely an issue with the volume. A poor quality cable will introduce line noise instead of volume issues.
If you are concerned, try a different cable.
It feels like the T1 isn’t pushing a lot of volume unless I crank the main up.
Is your concern that the overall volume is not high enough, or just the vocal?
On the L1 is the SIGNAL/OL light green with red flickers?
There are two LEDs on the PS1 Power Stand (Classic) / Model I near the Trim knob labeled Signal/OL -- one for Channel 1 and another for Channel 2.
These LEDs indicate when the signal level channel's preamplifier reaches certain important thresholds. The trim controls located near the LEDs adjust the amount of gain in the preamplifier.
- The LEDs turn from off → green when the signal level exceeds a small amount.
- The LEDs turn from green → red when the signal reaches a level that's about 10 dB below a level that would clip the preamp and cause objectionable distortion.
When the LED is off (but you are playing an instrument you think is connected to the PS1 or singing/talking into a microphone you think is connected): Increase the level of the trim control. If the LED still does not turn green or red, check the instrument/microphone and cables to the PS1.
When you see green only: This indicates that there's some signal in the channel but not enough. While singing or playing the loudest you ever plan to in the performance, increase the trim level until the LED is only flickering red. This is the optimal gain.
When you see red most of the time: Decrease the trim level until you see only flickering red. This is the optimal gain.
If the LED is green with red flickers, the cable from the T1 to the L1 is probably fine.
Or maybe that’s the Harmony Singer?
Is the Keyboard → Nano module loud enough? If yes, and your issue is with the vocals...
If you have a TC Helicon Harmony Singer (not Harmony Singer 2) try adjusting the MIC GAIN
