Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems TacT/DEQX room correction

Rodney, the standard TacT unit isn't transparent (to my ears) so could be the reason you didn't like it even in bypass. Third-party mods can improve this and I guess the new Boz/Lyngdorf stuff will also be an improvemnet. Of course, you should be able to replicate the parametic EQ of the Z-sys RDP-1 using the TacT's own parametric EQ mode.

Rodney,

I recently bought a 2nd hand RDP-1, and find the behaviour of the remote control a bit erratic. It often increments by 2 when it should increment by 1, which is a pain when trying to select an input. Have I bought a duffer, or do they all do this?

Mark , mine does that too, I got a chip upgrade from Z-Sys that was supposed to fix this (musta been at least 6-7 yrs ago), but it doesnt. In fact mine suddenly jumps from one function to another at times.
I did a workaround , I use a Programmeable remote - an old Sony RM something or other and havent had a problems since. I also have the Z-sys right by my listening chair and just twiddle the knobs.
I have experimented with various dither patterns Z-sys provide with mine and have fount that non of the dither modes work well compared to undithered and have also found that 20 bits out is by far the best for my old DSP5500s (non 24/96)
What is also nice about the RDP-1 is that you can sperate L&R chans and apply different settings to each.
What is the pits with it is this : It promotes MAJOR "fiddlitus" in that one is forever tweaking on a CD by CD basis to optimise the sonics , IE you think like this "if this setting is good , maybe a little tweak here and there is better"
I initially used it to notch out a very nasty bass hump in a very narrow band at about 37 hz in my old listewning room , I moved subsequent to that and now use it as a glorified tone cotrol, I also always dial in about 3db attenutaion cos if you boost any frequency , you can get digital clipping. Evidently it works in boost mode , by dropping everything around the freq you boosting. I have also found that small changes in centre freq ,slope or boost/cut , even as small as .2 db actually seem to change the percieved sonics quite a bit , more than would be expected but this may be a self fulfilling prophesy as I know I am increasing or decreasing a specific band and thus "imagine" the change more??

I could not maintain reliable control between the Crestron and the Tact TCS. The communcations would regularly fail, and it often required a hard reboot to get the unit to work again even under manual control. The unit was sent to Tact for repair, and they could not get it working either. I spent 12 months going back and forth and back and forth and finally I gave up in frustration. What was extremely frustrating was that Tact kept telling me their units worked fine with Crestron gear, but could not (or would not) send me either reference code that worked or connect me with a programmer that had succeeded with the unit. I concluded that they didn't really have it working yet, despite assurances to the contrary.

Since I had one of the earlier units put out, I assume but do not know that they've fixed this since then.

I also had problems with the unit "freezing up" when under manual control, which was independent of the Crestron issues.

It was a nice unit sonically, but ultimately Tact lost me on real world useability.


That being said, for the application being contemplated in the first post of this thread I suspect the unit would function well.

Thanks for the info Rodney. I do find the RDP-1 ergonomics come a poor second to Meridian's, although strangely the manual is very well written, and puts M's efforts to shame.

My only problems with the RDP-1 are (1) that it is 2channel only and (1) that it is digital-input only. The former precludes using it with all the channels on the digital feed from the player to the pre/pro and the latter precludes using it on only the main L/R speakers after the pre/pro. Sigh.

Outside of lacking analog inputs and other external hardware features, does anyone know the difference between the Tact 2.2XP and the new Mini? The website is not clear about this. Do they have the same DACs, for example?

In users' experiences, is the Tact helpful at high frequencies, or is it pretty much mids and below?

I am living the densely populated city, Hong Kong; and have a even harsher living room that are full of glass panel. So, I have similar situation with rblnr.

I am looking forward to a room correction device for DSP. Hope that gentleman here can share your experience with G68, TACT and others.

Many thanks

I'm going to stop by Tact tomorrow and hear the new Mini. I'll report.

rblnr,

Any feedback on the Mini or 2.2XP?
