– 1 – I NTRODUCTION 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 ( T rans • ana R eference M onitor) is an amplified 10" subwoofer monitor .
– 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 oofer Santoprene Rubber Surround Santoprene is a very durable and temperature tolerant material which provides the consistent support necessary for the linear motion of the speaker cone. In addition, the damping capabilities eliminate the transmission of sonic disturbances between the cone and the frame of the speaker .

– 9 – LOCA TION The acoustic properties and size of the listening environment can drastically influence the SPL (Sound Pressure Level) and f 3 (-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.

– 11 – O PERA TION 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.
– 12 – PHASE CONTROL The Phase Control switches allow the TRM10.1/TRM12.1 to be acoustically aligned with other speakers in your sys- tem. 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.
– 13 – AC LINE The TRM10.1 /TRM12.1 operate from a 1 15 V AC/60Hz power line. The TRM10.1SCE/TRM12.1SCE operate from a 230 V AC 50/60Hz power line. Connection is made by a 16-gauge, IEC T ype 320, grounded line cord. For safety considerations only a properly grounded (earthed) receptacle should be used.

– 17 – INPUT CIRCUIT The stereo input signals are connected to the amplifier through balanced XLR connectors, or unbalanced RCA con- nector 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 imped- ance, dominated by R10, R4, R42, and R32.
