A universal audio product that can improve any system.  Here’s what it can do:


  It’s an adjustable high pass filter for driving a main speaker amp.

  It’s a high current, low impedance buffer for superior driving of interconnect cables.

  It has an isolated, adjustable output for driving a subwoofer amp.

  It’s a headphone amplifier

  It’s a noiseless, unity gain, master volume control for directly connecting a signal source to your amplifiers.


The Sub Buddy’s outputs can provide up to 20 mA RMS of drive current into a 30 ohm load.  It has been discovered that high current output greatly improves sound quality by properly driving interconnect cable capacitance.  The longer the cable, the greater the improvement, but substantial gains will be attained with cables of three feet in length.  The sound is clearer with more detail and presence.  The Class A high current tubes will add a layer of richness to the sound.  This is especially beneficial for use with solid state amps. 


The high pass filter improves the performance of speakers when used with a subwoofer.  By rolling off the lowest frequencies, the loudspeaker is relieved of massive cone excursions which reduces distortion and smearing in the midrange and treble.  Stock frequencies are: FLAT, 50 HZ, 70 HZ, 100 HZ, 150 HZ, and 220 HZ.  Rolloff is a gentle, but effective 6 dB/octave.  The FLAT setting allows comparisons with no rolloff and also let’s the Sub Buddy function as a dual amp driver with independently adjustable outputs.  The Sub Buddy is customizable.  By changing the timing capacitors, any rolloff frequency can be set.  For example, by making the capacitors ten times smaller, each rolloff frequency will be be ten times higher.   


The Sub Buddy will provide 15 milliwatts into headphones with an impedance of 32 ohms.  That is enough power to produce moderately loud levels but not be uncomfortably loud.  Output increases with rising impedance and it can make 40 milliwatts into 100 ohms for better performance. 


Controls are simple but versatile.  The MAIN control adjusts the volume of both outputs.  The SUB control further allows the subwoofer output to be adjusted independently.  Once the volume is set as desired, the subwoofer can be easily adjusted, up or down, from the front panel.  No longer is it necessary to get down on the floor to adjust the subwoofer amp for changing music tracks.  The SUB control also sets the volume of the headphone amplifier. 


Many systems have sufficiently strong signal source and gain that an active preamp is unnecessary.  These systems are good candidates for use with a passive preamp.  The Sub Buddy is an ideal choice for such systems as it has no gain, and the high current drive will greatly improve the sound by better driving cable capacitance.  Passive preamps, by their inherit nature, insert a high impedance into the signal path which greatly chokes off the supply of current.  Replacing a passive preamp with a Sub Buddy will reveal detail you never thought existed. 

The Sub Buddy is also ideal for use with an active preamp.  It can also be directly connected to a phono preamp on a pure vinyl system.  It has been designed to sit on top of our Grounded Grid Preamp.
