Page 6: Introduction
Introduction Phonitor When we brought out the first Phonitor — the first ever headphone amp with 120 Volt technology — back in 2008, the professional audio world seemed to have been eagerly awaiting it. The success of this unique headphone preamp was overwhelming. In hindsight, we also had to wonder how none of us had come to the idea of com- bining basic monitoring options, speaker simulation capabilities and a headphone preamp. -
Page 7: Phonitor 2
Introduction Phonitor 2 Many Phonitor users told us they wished they could also use the unmatched signal quality that the Phonitor provides to feed their speakers. And so began to take form the idea of making its successor a full- fledged stereo preamp that could become the heart of modern pro- fessional and home systems alike where headphones have a pree- minent importance. -
Page 8: Phonitor Mini
Introduction Phonitor mini The outstanding technical and sonic characteristics of the Phonitor 2 were translated into a more compact and less-expensive format to create the Phonitor mini. Its ease-of-use, small and sturdy housing and affordable price, make the Phonitor mini the perfect headphone amp for home studios, hi-fi enthusiasts and mobile recording and mixing. -
Page 9: Home Listening
Introduction Home Listening Home users can now get — for an unheard-of value for money — a headphone amplifier to enjoy an authentic sound reproduction with headphones. 0° Headphones usually provide a 180-degree stereo image (the Super 30° 30° Stereo effect), and that‘s exactly where the problem is rooted. Generally speaking, music is mixed so that all instruments are repro- duced correctly in their position when the loudspeakers form a ste- reo triangle. -

Page 11: The End Of Ear Fatigue
Introduction The end of ear fatigue The initially impressive „Super Stereo effect” with headphones can become tiring with time. Besides the unnatural ambience impressions, other disadvanta- ges also lead to an early ear fatigue when mixing or listening with headphones. A cheap headphone amplifier can also be a good reason for early hearing fatigue. -

Page 21: Hook Up
Hook Up Connecting to the mains Be very careful to check that the rear chassis power selection is set correctly before using the unit (230V/50 Hz = 220-240 V, 115V/60 Hz = 110-120 Volt). When in doubt about a source, contact your dealer or a professional electrician. -
Page 22: Placement
Hook Up Placement Place the unit on a level and stable surface. The unit’s enclo- sure is EMC-safe and effectively shielded against HF interference. Nonetheless, you should carefully consider where you place the unit to avoid electrical disturbances. It should be positioned so that you can easily reach it, but there are other considerations. -
Page 23: Before You Begin
Hook Up Before You Begin Make sure the Volume control is turned hard left before you power up the unit. Now control Volume. Note that too high levels can damage headphones and hearing! Always MUTE the input before plugging in or unplugging a pair of headphones. -

Page 25: Control Elements
Control Elements Input: XLR or RCA The Phonitor mini provides two different source connections. Use the Input switch to select one. Both switches are named after the inputs on the rear. The RCA input is usually used to connect consumer products. Do note, however, that the XLR inputs can also be used to connect any unbalanced outputs . -
Page 26: Matrix: On Or Off
Control Elements Matrix: On or Off With Matrix On/Off you switch on or off the Phonitor-Matrix globally. On activates Crossfeed, Angle and Center, while Off deactivates them. A/B comparisons can be made directly. Phonitor mini... -
Page 27: Mode: Stereo, Mono Or Mute
Control Elements Mode: Stereo, Mono or Mute The standard setting of the switch is „Stereo,“ to play back stereo signals. The mono switch sums the two channels that make up the stereo signal. The mono switch is important to check the mono compatibility of the mix. -
Page 28: Crossfeed: Low, Med Or High
Control Elements Crossfeed: Low, Med or High The Crossfeed switch determines the volume-dependent, frequency- corrected channel crosstalk, which is something that occurs natu- rally with speakers, due to their sound projection into a room. This is called „Interaural Level Difference“ (ILD). The different Crossfeed values could be compared to the influence of different room sizes and characteristics on the same loudspeaker settings. -
Page 29: Angle: 30°, 22° Or 40
Control Elements Angle: 30°, 22° or 40° With the Angle switch you define the frequency-corrected channel crosstalk. In this case, we are dealing with „Interaural Time Difference“ (ITD). The influence of the point in time at which the signal reaches the opposite ear corresponds to the variation of the angle at which a real loudspeaker pair is placed. -
Page 30: Center: -0,6 Db, -1,2 Db Or Off
Control Elements Center: -0,6 dB, -1,2 dB or Off Normally, when using headphones, the mid signal is lower than the side signals, which seem louder due to the Super Stereo effect. When you adjust the stereo image of the speakers with the Crossfeed and Angle settings, the mid component may drop quite intensively. -
Page 31: Volume
Control Elements Volume The Volume level control allows you to decrease the signal level from between 0 and -80 dB. If the volume control is hard right, it is not set to -0 dB but rather to +7 dB. Always MUTE the input before plugging in or unplugging a pair of headphones. Otherwise, your headphones, ears or the power amplifier of the Phonitor may result damaged.. -
Page 32: Headphone Connection
Control Elements Headphone Connection Connect headphones to the standard 1/4“ (TRS) stereo plug on the lower left front panel. The layout is: Tip =left channel, Ring = right Channel, Sleeve = ground When connecting headphones, make sure that the plug is completely in and that is firmly attached. -
Page 33: Headphone Connection
Control Elements Headphone Connection Reduce volume level before you remove or plug in the headphone (or when switching headphones). That way you avoid loud crackles from reaching your ears or the power amplifier of the Phonitor mini being damaged due to the brief short circuit when plugging in or unplugging. -
Page 34: Rear Panel: Power
Rear Panel: Power Voltage Select Before connecting the Phonitor mini to the mains, make sure that the voltage selection corresponds to the values of your local power grid (230 or 115 volts). In German-speaking regions, it is usually 230V. The mains connector on the rear panel integrates a fuse box that inclu- des fuses for both voltage ranges. -
Page 35: Voltage Select
Rear Panel: Power Voltage Select Open the power connector lid with a small screwdriver. There are two tiny slots on the outside. Use the screwdriver to lever the red fuse box from above until you can grab it. Take the fuse box out, turn it around 180 degrees and place it back again. -

Page 39: Operation
Operation Setting up the Phonitor Matrix in three steps Initially choose your audio material from sources you know well, and in a first production, that which is similar to what you wish to mix. It is not sensible to listen to classic music while planning a Phonitor mini setup to mix a pop production. - Page 40 Operation Setting up the Phonitor Matrix in three steps Activate Crossfeed, Anlge and Center In order to hear the same as with loudspeakers, the audio chan- nels receive now precisely calculated time, level and frequency corrections. First of all, you should check the correct stereo width. If the stereo image on your headphones seems too narrow or too wide, you can always apply two corrections: Angle or Crossfeed.
- Page 41 Operation Setting up the Phonitor Matrix in three steps Angle: First of all, you should approximate the desired stereo width with the Angle control (which corresponds to the positioning angle of a real loudspeaker set), and then adjust the Crossfeed (which corresponds to the influence of the room size and damping on the loudspeaker).
- Page 42 Operation Setting up the Phonitor Matrix in three steps Crossfeed: If you increase the Crossfeed value, a higher amount of signal is added to the opposite side. Which results in a smaller Interaural Level Difference. Phonitor mini...
- Page 43 Operation Setting up the Phonitor Matrix in three steps Center: After you have set up Crossfeed and Angle you can then determine your Center Level setting. When simply playing back audio material (home use), the Center function can usually be set to Off. When mixing, the phantom center is usually too low.
