I NTRODUCTION – 1 – Thank you and congratulations on your purchase of the HAFLER TRM6.1 reference monitor , the world's finest brand in professional audio equipment.
Amplifie – 2 – MEHSA ( M aximum E fficiency H eat S ink A pplication) MEHSA is a proprietary process that yields up to 5 times better heat transfer than traditional FET mounting techniques using the exact same components.
– 3 – W ave Guide The wave guide is a proprietary axis-symmetrical form of horn mounted to the tweeter to increase efficiency . The wave guide improves the transition of sound waves (from planar to spherical) smoothly from the throat of the wave guide to the mouth.

LOCA TION The location of your reference monitors in addition to the acoustics of the listening room will influence the system frequency response. In the near field environment, our ears are more sensitive to direct sound rather than the reverberation of sound.

INPUT SENSITIVITY The Input Sensitivity adjustment is used to match the monitor with signal levels from a variety of mixing consoles. The Input Sensitivity uses DIP switches to match input levels over a 15dB range and are marked +1dB, – 2dB, – 5dB, – 8dB, and – 1 1dB.
BASS SHEL VING 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 marked +4dB, +2dB, – 2dB, and – 4dB.
POWER SWITCH The POWER switch is located on the front panel. The LED will illuminate GREEN, indicating the respective amplifiers are on. It is possible to leave the power switch in the ON position and switch the monitor remotely through a power distribution block or switched outlet.

CIRCUIT OPERA TION trans • ana Implementation The transistor Q24 is configured to operate as a switch that controls the constant current source Q21 of the differ- ential amplifier Q27 and Q28.
The input signal is connected to the amplifier through the balanced XLR connector J1, or the unbalanced RCA connector J2. Balanced/unbal- anced switch DS1 will ground the inverting input buffer , allowing operation with an unbalanced signal on either connector .
W oofer Crossover The input signal at U4A pin 1 connects to the 3200Hz 2nd order low-pass filter at U1 12B. Approximately 2dB of additional gain can be added to this stage by adjusting R136 against the divider resistor , R137. The next stage is a 30Hz – 60Hz switchable sub-sonic high-pass filter .
– 23 – Clipping Indicator The CLIP indicators are driven by the comparator U5A and U5D. The voltage divider R56, R57, and R51, R61 establishes the reference voltage for the Clipping detector at pin 7 of U5A and pin 9 of U5D. Excessive drive sig- nal at pin 6 or pin 8 will trigger its comparator low and light the CLIP/THERMAL indicator red.
