Installation of TacT RCS 2.0 version 1.3 software
Important notice:
If the RCS 2.0 was previously programmed with software version 1.2, you should only
complete step 1. (This update will allow you to use the TacT-20 software with WIN2000 & NT)
If the RCS 2.0 was programmed with version 1.0 or 1.1 you should complete both step 1
and 2. (See page 3 for new features in the software)
Step 1:
• Connect the RS232 communication cable between the computer and RCS 2.0 and
turn power ON.
Remove the old software installation by 1) deleting the “TacT-20” folder in the
•
“TacT Audio” directory or 2) by using the Windows un-install utility “Add/Remove
Programs” under Windows “Control Panel”.
Insert the software disc, select your CD-Rom drive from windows desktop “My
•
Computer” and double-click on “Install-Tact-20 v1.3”. (If downloaded from webpage, locate the file and double-click on the “Install-Tact20 v1.3” icon)
Follow the on-screen instructions. *DO NOT CHANGE ANY OF THE
DIRECTORIES WHEN PROMPTED.
• Click “Finish” to complete and exit the installation
Step 2:
Launch the RCS 2.0 PC software
•
Loading of new software to 2.0:
1. Put 2.0 in standby, and switch it OFF from the rear-panel main-switch.
2. Hold down the Analog and Digital input selectors while turning the unit ON from
the rear-panel. The display will indicate: PROGRAMMING MODE.
3. From the RCS-2.0 software main screen, select “Add-inns”, select "Standard" and
press "Program". The software will ask you to confirm the programming sequence.
When programming is completed, TacT RCS 2.0 will return to normal display-mode.
4. Exit programming screen.
5. Select “PR” from the RCS-2.0 software main-screen – this will open a new
window. Click on “Clear” and press “S” while holding down the “Control” key. This
will open up two boxes. Check the “System” box and leave the “Parametric EQ” Box
un-checked.
6. Press “Program” and confirm by pressing “Yes”. Close the “PR” window when
finished.
The RCS 2.0 is now programmed.
After this the unit will have the new software which include the following changes:
1. 6 dB additional digital gain. Please note that this will give full volume on a fully modulated
CD when the main volume display indicates 93.9. So use the additional gain only for CDs
that are recorded at a low level, or to enhance a low level passage on a CD. In connection
with the M1 the level should normally be set at 93.9. ( on the left of the display you will see
the attenuation which will be 0.0 dB at 93.9 on the main volume display.)
2. In the menu system there will be an “OUT” sub menu. In this you can select if 2.0 should
play Stereo, Mono, Left channel signal on both channels or Right channel signal on both
channels. This will allow you to use 2 pcs of 2.0 in parallel for crossover applications etc.
3. One step further to the right of the OUT menu there is an analog menu. In this you can
adjust the output level of the analog section by +- 6dB. Use the higher setting for low input
sensitivity power amplifiers and the lower setting for high input sensitivity amplifiers. You
will get the best overall signal to noise level if you adjust so that the 2.0 will just drive the
amplifier into clipping at 93.9 on the main volume. So do not use more gain than necessary.
4. "Rem" menu is used for turning remote control on / off.
5. "ADDR" should be set to "001". This is the units device address and is used if multiple
TacT products is controlled by same computer.
Import of measurements to target curve screen:
This feature allows you to compare directly between the measured response and the target
response. To use this feature please follow these steps: From the correction screen select edit
left. This will bring up the target curve screen. Go to “File” and select “Import Measurement
M1”, select a measurement from the Windows file system ( The latest measurement will
automatically be suggested ). Pick the left channel measurement by double clicking on
msrl_l1. Then pick the right channel by clicking on msr_r1. Now the left and right channels
will be displayed together with the target curve. Align the levels of the measurement with the
up-down arrows for M1 and M2.
This will allow you see exactly how much your target curve differs from your measured
response. If – for instance – you do not want to change the overall tonal balancing of your
speaker system at the higher frequencies then just plot the target curve according to the
speakers natural response. Also you will be able to see directly how much correction will be
applied at any frequency.
Less than full correction:
On the correction screen in the middle a new window displays: “Full”. Click on the down
arrow and you have 3 options: “Full”, “Medium” and “Low”. This option will allow you to
select less accurate correction. This can be desirable for instance if the speaker system has
limited dynamic range or for very low playback levels. ( when you use the system for
background playback at very low levels then the fully corrected sound can appear too tight
and controlled )
The default setting is “Full” – this obviously will give you the complete correction of the
frequency inaccuracies. The level of correction must be selected before correction is
calculated. If you want to change one memory position from full correction to medium or low
correction, then just select the desired option and push the “GO” button on the lower half of
the screen. Then the system will re-calculate using the existing measurement and the selected
target curve.
