Symbols and Notes Symbols And Notes IN THIS MANUAL A LIGHTNING SYMBOL WITHIN A TRIANGLE WARNS YOU ABOUT THE POTENTIAL FOR DANGEROUS ELECTRICAL SHOCKS – WHICH CAN ALSO OCCUR EVEN AFTER THE MACHINE HAS BEEN DISCONNECTED FROM A POWER SOURCE. AN EXCLAMATION MARK (!) WITHIN A TRIANGLE IS INTENDED TO MAKE YOU AWARE OF IMPORTANT OPERATIONAL ADVICE AND/OR WARNINGS THAT MUST BE FOLLOWED. BE ESPECIALLY ATTENTIVE TO THESE AND ALWAYS FOLLOW THE ADVICE THEY GIVE.
Important Security Information Please note and retain this manual. Carefully read and follow all of the safety and operating instructions before you use the machine. Be doubly careful to follow all warnings and special safety instructions noted in this manual and on the unit. Connections: Only use the connections as described. Other connections can lead to health risks and equipment damage.
Important Security Information Air Circulation: Chassis openings offer ventilation and serve to protect the machine from overheating. NEVER cover or otherwise close off these openings. NEVER place the machine on a soft surface (carpet, sofa, etc.). Make sure to provide for a mounting space of 4-5 cm/2 inches when mounting the machine in racks or cabinets. Controls And Switches: Operate the controls and switches only as described in the manual.
Hook Up Be very careful to check that the rear chassis power selection switch is set to the correct local line voltage position before using the unit (230 V position: 220-240 V/50 Hz, 115 V position: 110-120 V/60 Hz)! When in doubt about a source, contact your dealer or a professional electrician. Before connecting any equipment make sure that any machine to be connected is turned off. Follow all safety instructions from page 5. Place the unit on a level and stable surface.
Introduction There is more than meets the eye in working with headphones. A reason for this surely lies in that modern audio production often necessitates decentralized processes. In turn, production phases following such plans more often take place in acoustically questionable rooms.
Introduction Applications Aside from its outstanding abilities as loudspeaker substitute the Phonitor offers well equipped studios a fully functional monitoring alternative. In addition one can take along the Phonitor into an unfamiliar studio or production environment that always provides the engineer’s own monitor sound. Furthermore, with the Phonitor one can simply enjoy music as it was originally mixed, namely for playback over loudspeakers.
Introduction With And Without Magnifiers, The End Of Ear Fatigue On loudspeakers such analyses are much more difficult, as such problems just are not as apparent when one is working without being able to “zoom in” aurally. Conversely, loudspeakers provide monitoring with the advantage of spatial balance in a (definable through placement) stereo width, which in turn provides the illusion of an acoustic stage.
The End Of Ear Fatigue Introduction For some years, now, SPL has addressed this issue in all of its mastering product series through its own specifically developed 120 volt technology. Consoles and signal processors of the SPL Mastering Series appear as central elements in installations of today’s most renowned mastering houses (z. B. Bob Ludwig’s Gateway Mastering & DVD in the USA, Simon Heyworth’s Super Audio Mastering in Great Britain or the Galaxy Studios in Belgium).

Connections & Switches Rear Panel/Connections Voltage The rear panel voltage selector switch serves to let the user switch to the local line voltage standard. IMPORTANT ADVICE: Before you use the Phonitor, make sure that this switch setting reflects the correct local power line voltage (115 V position: 110-120 volts/6o Hz, 230 V position: 220-240 volts/50 Hz). Power Connection Connect the included power cord to the rear Mains Input.

Control Elements Crossfeed, Speaker Angle Crossfeed The Crossfeed switch allows you to adjust the frequency-dependent crossfeed simulation of both channels by adjustments of interaural level difference – as if this characteristic would be heard from monitors when in their own room ambiance. One can compare variations in crossfeed values as approximating the influence of different room sizes and characteristics on a given loudspeaker setup.
Crossfeed, Speaker Angle Control Elements Interaural Level and Time Differences as Related to Crossfeed Setup The following two diagrams show, respectively (on the left), the frequency response of interaural level differences and (on the right) the interaural time difference at maximum Crossfeed value and at a Speaker Angle of 30 degrees.
Control Elements Crossfeed, Speaker Angle Interaural Level and Time Differences as Related to Speaker Angle Setup The following two diagrams show (on the left) the frequency response of interaural level difference with respect to the interaural time difference (on the right) at maximum Crossfeed value and a Speaker Angle of 75 degrees.
Control Elements Crossfeed, Speaker Angle Crossfeed and Speaker Angle Parameters Speaker Angle Switch Crossfeed Switch Level Difference Time Diff. (µs) Speaker Angle (Result) The accentuated lines show at which Crossfeed values the Speaker Angle most precisely matches the theoretically determined time difference values. These, of course, are mainly a starting point to reproduce a real monitoring setup. Formulae for calculations from http://www.sengpielaudio.
Control Elements CROS./SPK., Center Level, Center Off/On CROS./SPK. With CROS/SPK. you switch on or off Crossfeed and Speaker Angle functions globally. This provides for direct A/B comparisons. $& Center Level E# Your impression may at first be that the results are not so spectacular as expected – until you consider that the Phonitor is not an effects machine.
VU Meter, Signal LED, Overload LED Control Elements VU Meter The VU meter displays the input level for each channel. The gauge indicates levels from -20 dB to +5 dB. If necessary you can lower the sensitivity by 6 dB so that the gauge goes up to +11 dB output level (see “Meter Cal.“ on page 22). The VU meter is custom made to meet SPL specifications and assures a balanced optical perception thanks to it’s optimized ballistics.
Control Elements Meter Mode .&5&3 .0%& 76 11. With this switch you can change the sensitivity of the VU display. If you choose the +6 dB position, the range of the display is extended by 6 dB. With the +6 dB switch activated and the needle at 0 dB, a value of +6 dB input level is displayed. Dim %*. 0'' The Meter Mode switch allows to switch the VU metering characteristics from VU display mode to PPM display mode.
Solo, Phase ø Control Elements Solo You can engage the solo switch to monitor only the left or right channel of the stereo signal. The Solo switch has three positions: L, R and OFF. The middle or OFF position allows monitoring the stereo signal. Switched to L or R, and you will hear only the left or right channels, respectively. A selected solo channel defaults to retain in its respective left or right position, and we call this function “Solo-in-Place”.
Control Elements Mono, Volume Mono The Mono switch creates a sum of the stereo channels. If, per the above description, you employ this Mono switch along with the Solo, the overall signal level will be approximately 6 dB below a stereo signal and mono-switch only. This is normal, since in Solo mode only a single mono channel is active.

Operation QUICK GUIDE To Monitoring Functions You should now compare what you hear with headphones and loudspeakers. First, whether or not you have the correct width in your stereo image. If this appears too narrow or too broad with the headphone, you have always two ways for further adjustments: A. Increase Crossfeed. With this approach more of each channel is mixed to the opposing side, but the Speaker Angle remains unaffected. Technically speaking, this process changes the interaural level difference.
Operation QUICK GUIDE To Monitoring Functions 5. After you have set up Crossfeed and Speaker Angle, you can then determine your Center Level setting. Although at normal hearing levels over headphones the center signal generally seems too quiet, after Crossfeed and Speaker Angle processing it then can seem too loud. Therefore the center level can be lowered to avoid this effect.

High THD values can be perceived as rough sounds and overemphasized highs. In usual operating ranges around 0 dBu, the Phonitor‘s THD values are extremely low. With a 0 dB input signal and 600 Ohm headphones the SPL is at ca. 83 dB (stereo signal in 3 cm distance).
