Yamaha TF Series Tutorial Video: Output Sound Tuning


On the day of a show, after the equipment is in position and connected, the first thing a sound engineer does is to tune the outputs. You need to tune the system to find a best match between the speakers and the acoustics of the venue, using EQs, dynamics and so on. This can be time consuming, and really boring for the musicians who are just hanging around and waiting for the sound check. So with TF, we have a simple solution: Output Channel Presets! The TF Output Channel Preset Library contains optimal parameter sets for Yamaha powered speakers, with several variations depending on the type of room,
its size, and the application. There are even presets for in-ear monitors too. They are a great starting-point for manual fine tuning, or use them just as they are when time is limited! The presets will be added to with firmware updates and web downloads, and you can even create your own. So if you return to a familiar venue, you can recall exactly the same setting as before! So let’s take a look at how to do your own output tuning. On TF, all the output buses have parametric EQ and compressors. Use the multi-touch screen to intuitively shape the sound. For quick adjustment, and for less experienced users, there are the “1-knob EQ” and “1- knob COMP” facilities. They provide a simple “one knob does it all” adjustment for the sound. For example, create a good EQ curve that suits the situation, and then use the “1-knob” “Intensity” mode to adjust the feel, perhaps as the room fills up with people. Alternatively, set the output EQ to “Loudness Mode”, and use the 1-knob function to increase the sound pressure level
as you turn it clockwise. This is a new and unique feature that’s going to
save a lot of time and hassle, for both experienced and novice users alike! The “1-knob COMP”, like the EQ, also allows one knob to
control a whole bunch of parameters. It takes time to learn how to use a compressor effectively,
with the attack, release, threshold and ratio parameters all shaping the sound in different ways. The “1-knob COMP” makes it easy: just turn it clockwise to apply stronger compression, and it takes care of all the parameters automatically! You can get a polished, controlled sound on stage and through front-of-house so easily now! The eight mono AUX buses and the main Stereo output have an additional feature, very useful for controlling the sound during live events:
the Flex12 GEQ. This is a full 31-band graphic EQ,
from which you can adjust up to 12 bands. Use it for fighting feedback and for making last minute adjustments to the sound. By the way, the Sub bus has a Low Pass Filter available, to ensure the subwoofers only receive the required low frequencies. If you touch the frequency graph while using the parametric EQ or the graphic EQ, a real-time analysis of the sound is displayed. This is an incredible tool to help you adjust the sound. You can see which frequencies are producing feedback,
so you quickly know how to fix it. A piano keyboard is displayed on the lower part of the RTA display, to make it easy to communicate with the musicians about which notes on their instruments may be causing feedback, buzz, or other resonance. Just another tool in the TF to help the sound engineer achieve impressive results!
