Speaker Mode - NHT M-60 Xd Owner's Manual

SPEAKER MODE:

The XdA is programmed with four different filters for each of the two channels. Each of these filters is
designed for a particular application or acoustic setting. For example one filter might have a bass rolloff
at 80Hz for use with a subwoofer. Another filter may have rolled off high frequencies to compensate
for a very reflective room, while another may cut the low frequencies of the M-60 Xd sharply to allow
it to produce higher SPLs. The combination of these eight filters is called a filter set. Contact NHT or
visit our website at www.nhthifi.com to find out what other filter sets are available for your M-60 Xd
system.
The ability of the M-60 Xd system to change performance characteristics simply by changing the filter
set is one of the great advantages of DSP processing that the M-60 Xd system offers. What follows
below is a description of the stock filter settings in the M-60 Xd system as shipped from NHT and how
to access them.
Each filter setting is accessed by the mode buttons on the front panel of the XdA. The left mode
button accesses the four filters for channel 1, the right button accesses the filters for channel 2. To
change the filter setting for one of the channels, simply depress the mode button for that channel until
the appropriate icon is illuminated. The top icon is for filter setting #1, the next icon down is for filter
setting #2 and so forth.
Set 1:
In this filter setting, the system has a flat
frequency response that rolls off slowly below
70Hz.
Set 2:
In this filter setting, the system has a flat
frequency response that rolls off sharply below
45Hz.
