TAI 190/300/550

It's certainly helped in my case (just put rubber feet on my TAI-300 yesterday; it sits on a hardwood, suspended floor) - sound cleaned up a lot.

I have applied the rubber legs to my TAI-300 but I have a problem with super-sensitive volume control on the sub. There is a certain point (maybe around the 10-15% imaginary mark - below it there is almost no output and just above it the vulume is way too much to the point of things rattling in the room. I have a good preamp Anthem so don't think the issue is in my system or settings.
Has anyone had this volume control issue also?

I have not had that issue with my TAI-300, but I can attest to the volume level being high even at low knob settings. When I reduced the volume of my active monitor L/R speakers a while ago the TAI-300 was overpowering the room. So I started cutting the sub gain on the plate amp...and cutting more...and cutting more. I think I'm currently at about 15% of the volume setting. So the gain seems to peak sharply as you turn the knob up.

If it is a real problem you can't solve, contact Chane and they will try to help you fix it.

You may want to post a final equalized plot too, jwskud.

hello Chane,

I have an issue with a super-sensitive gain knob on the plate of the 400 sub...so i was researching more and have another question regardng the built-in 80 Hz, 12 dB/octave, high-pass filter on the low-level outputs on the TAI-300...

assuming i set up the crossover control to 150hz does that mean that sound below 150hz wil goto sub and sound above 80hz will go to speakers? thus the range 80-150 is reproduced twice. both in the sub and in the speaker?

Low Level High Pass Outputs
These outputs provide the signal that goes to the power
amplifier that drives the main speakers in the system.
The signal from these outputs is high pass filtered
(80 Hz, 12 dB/octave) to remove bass sounds.

Crossover Frequency Control
This control sets the frequency of the low-pass filter,
and is fully adjustable from 50 to 150Hz. Bass sound
below the frequency set by the control are directed to
the Basis 300 / IC-Basis 300 amplifier and speaker

Typically you'd just leave the low pass filter knob turned all the way up to 150Hz. On your AVR set LFE to 120Hz and set your crossover to 80Hz. The speakers will begin to roll off above the crossover point at around 90Hz and the sub will begin to roll off below that point at around 70Hz. There will be a slight dip where the two intersect, but there's a boost in SPL at the dip because both the speaker and Sub will be recreating sound in that area. The sub will completely roll off at 120Hz.

So even though the knob on the sub is set at 150Hz, the sub will only be reproducing the signal its being fed from the AVR.

If you were to hook up your speakers using the high pass filter, which is the speaker wire hook-ups, it would be a different setup procedure that does utilize that knob.

thanks for the instructions mate! however, i should have clarified my set up first - I am using the sub to augment my front speakers lows:
- left and right channel RCA cable from preamp to sub and then RCA from sub to amp. And speaker wire from amp to speakers.

with that said, how should i be setting the controls on the sub plate amp?
