Page 6: Introduction
Introduction Thank you and congratulations on your purchase of the HAFLER series of Subwoofer, the world's finest brand in professional audio equipment. The VRM series is comprised of three modules; the VRM10s, VRM12s, and VRM15s. The VRM10s is an amplified 10" subwoofer. The VRM12s is an amplified 12" subwoofer and the VRM15s is an amplified 15"... - Page 7 MOSFET Devices HAFLER is one of the few manufacturers in the sound community to utilize MOSFET devices in the amplifier output stage. MOSFET (Metal Oxide Semiconductor Field Effect Transistor) devices offer sev- eral important inherent advantages over older bi-polar designs. These advantages include: thermal sta- bility, fast switching speed, ultra low output impedance and wide bandwidth linearity.

Page 13: Operation
Operation Auto Turn-on / Sleep Mode The VRM subwoofers automatically turn on when they sense an input signal. When the signal being fed to the VRM is turned off, the subwoofer’s amplifier will turn off and go into “sleep mode.” This feature eliminates the inconvenience of operating a mechanical power switch. -
Page 14: Phase Control
Operation Phase Control The Phase Control switches allow the VRM subwoofer to be acoustically aligned with other speakers in your system. 0˚, -90˚, -180˚, or -270˚ degrees of phase shift at 80Hz can be selected using DIP switch- es 2, 3, and 4. For 0˚ degrees of phase shift, leave all three switches in the OFF (up) position. –270˚ degrees of phase shift occurs when switch 2 is selected in the ON (down) position. -
Page 15: Ac Line
AC Line The VRM10s/VRM12s/VRM15s operate from a 115 VAC/60Hz power line. The VRM10sCE/VRM12sCE/VRM15sCE 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. -
