– 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 . The TRM12.1 is an amplified 12" subwoofer monitor . Both models of[...]

– 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. A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward and outward to quickly d[...]

– 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 . This greatly imp[...]

– 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." For the most p[...]

– 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." This feature eliminates the inconvenience of operating a mechanical sw[...]

– 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. -270 ˚ of phase shift [...]

– 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. If a grounded circuit is not available, d[...]
