Hafler TRM6.1, Installation & Operation Manual

Page: 23 / 36

BASS SHELVING
Bass Shelving is used to match the low frequency response of the monitor to the acoustic environment. Bass Shelving
uses DIP switches to control frequencies from 40Hz to 200Hz over an 8dB range and are 4dB, +2dB, –2dB,
and –4dB. When all switches are in the OFF (left) position, the bass level is at 0dB.
NOTE: When using the BASS SHELVING & TREBLE SHELVING, select only one switch configuration at a time.
Engaging multiple switch configurations (i.e., moving two or more switches ON) may cause undesirable operation and
is NOT RECOMMENDED.
TREBLE SHELVING
Treble Shelving uses DIP switches to control frequencies from 5kHz to 20kHz over an 8dB range and are 4dB,
+2dB, –2dB, and –4dB. When all switches are in the OFF (left) position, the treble level is at 0dB.

AC LINE
The TRM6.1 operates from a 115 VAC/60Hz power line. The TRM6.1CE operates from a 230 VAC 50/60Hz power line.
Connection is made by a 16 gauge, IEC Type 320, grounded line cord. For safety considerations only a properly ground-
ed (earthed) receptacle should be used. If a grounded circuit is not available, do not break off the ground pin; use the prop-
er adapter plug for a two wire receptacle with the grounding plug suitably connected to earth ground.
IMPORTANT: The power line fuse is mounted on the rear panel. If this fuse blows, replace it only
with the same type and rating as indicated in the parts list.
