George, thanks for bringing up the 'low to high impedance transformer' adapter option. Because Tyros2 includes both a mic trim on the back of the keyboard, as well as a separate mic volume knob up front, I've never experienced insufficient mic signal input (and using a variety of Dynamic low impedance mics from EV, Shure, AKG, to Sennheiser) coming directly into my Tyros keyboards (T1 & T2), using the simple 1/4" to XLR cable setup that I've use for years (as shown above). With my setup, both mic trim & mic volume knobs are maintained at around the 1:00 setting. I detect no noticeable added signal noise from the Tyros mic trim signal boost.
I'm really curious now though, if using a low to high impedance transformer such as the SignalFlex model# SF8021
, 'how much' of an increased mic signal input gain will be noticed. Assuming that the transformer adapter doesn't create signal noise, I would expect that this would mean being able to significantly lower the Tyros2's 'mic trim' setting, and effectively reduce any potential mic trim gain induced noise, right? I'm curious to find out by how much. As my mic trim is currently set at 1:00, what might I expect to be able to lower my Tyros2's mic trim setting to: 12:00, 11:00, 10:00, 9:00, 8:00, 7:00?
If there really is a noticeable performance gain adding a low to high impedance adapter, I'm probably add this as well, especially when recording.
Thanks. - Scott
PS: George, hope your back's feeling a lot better now. Best wishes in your recovery.
