INTRODUCTION Thank you and congratulations on your purchase of the HAFLER TRM10.1/TRM12.1 reference monitor, the world's finest brand in professional audio equipment. The TRM10.1 (Trans•ana Reference Monitor) is an amplified 10" subwoofer monitor. The TRM12.1 is an amplified 12" subwoofer monitor. Both models offer unmatched quality and performance in a truly professional grade product. The TRM10.1/TRM12.1 are great for Professional Studios, Digital Work Stations, Broadcast Booths, and Home Project Studios.
Amplifier MEHSA (Maximum Efficiency HeatSink Application) MEHSA is a proprietary process that yields up to 5 times better heat transfer than traditional FET mounting techniques using the exact same components. A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward and outward to quickly dissipate heat from each device across the heatsink.
Subsonic Filter The TRM series uses a Subsonic Filter to prevent the woofer from reproducing inaudible frequencies. Subsonic frequencies (known as infrasonic frequencies) are signals below the normal human hearing range and are generally considered to be below 20Hz. The subsonic filter reduces the energy of these frequencies and restrains the woofer from operating outside its optimum linear excursion.

INSTALLATION LOCATION The acoustic properties and size of the listening environment can drastically influence the SPL (Sound Pressure Level) and f3 (-3dB roll-off) of the subwoofer. However it's important to note that large or small acoustic spaces have little to no effect on the subwoofer cone excursion & box "Q." For the most part, we'll discuss the optimum location for two different installation methods: Studio Installation and Home Theater Installation.
INPUT SWITCH The unbalanced input uses a conventional RCA phone jack. Move the input switch to RCA UNBALANCED to use this jack. The balanced input jack is an XLR plug. The XLR jack is connected according to the IEC and AES standard. Move the input switch to XLR BALANCED to use this jack.
OPERATION AUTO TURN-ON / SLEEP MODE The TRM10.1/TRM12.1 subwoofers automatically turn on when they sense an input signal. When the signal being fed to the TRM10.1/TRM12.1 is turned off, the subwoofer's amplifier will turn off and go into "sleep mode." This feature eliminates the inconvenience of operating a mechanical switch. INPUT SENSITIVITY (GAIN) The Input Sensitivity is used to match the TRM10.1/TRM12.1 with signal levels from a variety of mixing consoles.
PHASE CONTROL The Phase Control switches allow the TRM10.1/TRM12.1 to be acoustically aligned with other speakers in your system. 0˚, -270˚, -180˚, or -90˚ of phase shift at 80Hz can be selected using DIP switches 2, 3, and 4. For 0˚ of phase shift, leave all three switches in the OFF (up) position. -270˚ of phase shift occurs when switch 2 is selected in the ON (down) position. -180˚ can be achieved by selecting both switches 2 and 3 in the ON (down) position.
AC LINE The TRM10.1 /TRM12.1 operate from a 115 VAC/60Hz power line. The TRM10.1SCE/TRM12.1SCE operate 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 grounded (earthed) receptacle should be used. If a grounded circuit is not available, do not break off the ground pin; use the proper adapter plug for a two wire receptacle with the grounding plug suitably connected to earth ground.

TRM10.1/12.1 FUNCTIONAL BLOCK DIAGRAMS Qualified Service Personnel Only INPUT CIRCUIT The stereo input signals are connected to the amplifier through balanced XLR connectors, or unbalanced RCA connector TP2. Unbalanced operation can be selected with switch DS1, which grounds the RCA shell through R37. Input buffers U1 and U10 provide a stable input impedance, dominated by R10, R4, R42, and R32.
Qualified Service Personnel Only CLASS-G TRANS•ANA AMPLIFIER The transistor Q8 is configured as a switch, which controls the current source Q5, of the input differential amplifier Q11 and Q12. If the power On/Off, Signal Sensing, and Thermal Protection circuits have all stopped pulling to -15V, the turn-on process begins, and the voltage at the emitter of O8 slowly ramps up to zero Volts according to the charging time of soft start components R13, C93, and C94.
Qualified Service Personnel Only POWER ON/OFF CIRCUIT The power on/off circuit is designed to turn the amplifier on slowly and off quickly. When AC power is initially applied to the subwoofer, AC signals on the secondary of the power transformer are negatively rectified through CR2 and CR7 into peak holding capacitor C31, and divided by R19 and R20. When the resulting DC voltage at pin 2 of U15A is lower than the -1.
Qualified Service Personnel Only CIRCUIT CALIBRATION Bias: The bias control establishes the quiescent Class AB output current of the amplifier. The bias should not need readjustment from the factory setting; however, if the amplifier is repaired and the output devices have been changed, calibrating the bias is necessary. Disconnect the power to the amplifier before removing the heatsink assembly from the speaker cabinet.
