Tact-2.2 XP RCS/DRC Quick Start

This quick start will guide you through the entire room correction process. The

quick start is divided into four steps.

Step 1 Explains how to prepare 2.2 XP for the correction process.
Step 2 Deals with room measurement.
Step 3 Explains how to perform standard room correction based on one reference target

curve.
Step 4 Explains how to perform dynamic room correction based on one reference target

curve and eight additional dynamic target curves.

Before continuing with the room correction process it is strongly recommended
that you connect your 2.2 XP to your audio system and that you make sure that it
properly plays music on all connected channels.

In this example we assume a 2.2 system with two main loudspeakers and two
subwoofers. We also assume that the subwoofers need to have a crossover filter of 200
Hz.

The subwoofer to main loudspeaker crossover frequency is usually provided by
the loudspeaker manufacturer. If you do not have this information you can perform a
system measurement, load the measurement data, and based on the loudspeaker response
easily determine this parameter. There is no definition for what the exact value of the
crossover frequency is, but rather there is a range of frequencies that you can use to
experiment with. The Tact 2.2 XP allows for on-the-fly crossover and target curve
adjustments which makes the process of selecting this parameter easy, fast, and extremely
accurate.

If your subwoofers are self powered they usually have a built in crossover

network. To take full advantage of the 2.2 XP crossover feature, it is recommended that
you disable the subwoofer internal crossover filter or set it to its maximum value.

Step 1 - Preparing the Tact-2.2 XP for Correction

Before using the 2.2 XP as a correction system make sure of the following:

1. Tact-2.2 XP is powered and properly connected. The PC RS232 port has to be
connected to the Tact-2.2 XP RS232 INPUT connector and not to the Tact-2.2 XP
RS232 AUX port connector.

2. Place the microphone at the listening position and connected it to the Tact-2.2 XP
microphone input.

3. Start the Tact-2.2 XP program. Click on the COM button (1 in Fig.1) to enter the
RS232 Connection to Tact-2.2 XP screen. Verify that RS232 communication is
functioning properly and then exit this screen.

If all of the above is correct, click on the RCS/DRC button (2 in Fig.1) to enter the
correction screen.

Step 2 - Measurements

Click on the

BP

(bypass) option (1) on the

As soon as you enter the RCS/DRC screen the 2.2 XP status data will be uploaded and
displayed on the screen.

The next step in the room correction process is the room measurement.

• Select bypass correction preset and disable crossover filters

Action panel. This will place the 2.2 XP into

bypass mode.

Fig. 2. Action panel.

Note that if system measurement is performed in correction preset other than BP,
the measured response will include room response combined with correction and
crossover filter response. If the measurement is performed in BP with enabled
crossover filters, the measured response will include room response and crossover
filters response.

Use the

Tools

pull-down menu and

select the Crossover menu option.
Uncheck Enable CRO check box
(1) to disable bypass preset
crossover filtering. Click on OK to
close this window.

Fig. 3. Crossover filter selection.

When crossover filters are disabled “None” is shown in both the CRO-SUB and CRO
filter description fields (see Fig. 5 panel 2). You can also enter Cro Filter screen by
double clicking in any of these fields.

Note that all measurements that are intended to be used for correction purposes
must be done while the 2.2 XP is placed in bypass correction mode with the crossover
filters disabled. If measurements are performed in a correction preset different than
bypass, the measurements will then include correction filters in the measured response.
Also, if crossover filters in bypass mode are not disabled, their response will be
included in the measured response.

• Enter the Measurement screen

On the Action (Fig. 2) panel click on the MSR button (2) to enter the measurement
screen (see Fig. 4). The measurement screen is used to perform room response
measurements. There are only a few measurement parameters that need to be set before
starting the measurement process.
