Phonitor 2

Adjust Headphone Reproduction To Loudspeaker

Monitoring

The Phonitor 2 offers foremost a complete set of options required for

professional monitoring: Solo L/R, Phase Reverse L/R, Mono, Volume,

VU Metering.

In addition, new functions such as Crossfeed, Angle and Center Level

transform the Phonitor 2 from a traditional headphone amplifier into

a headphone monitoring amplifier, with which it is possible to achieve

reproduction equivalent to studio monitors, if essential factors of

music production are considered.

We recommend proceeding with the following five steps:

1. 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 2

setup to mix a pop production. Classic music stereophony record-

ing involves a much more restricted stereo width than pop or rock

music, where artificial “panorama stereophony“ often provides for a

much broader imaging. Compare and match the volume of speakers

and headphones.

2. Note that you should be able to switch quickly and smoothly be-

tween speaker and headphones when making comparison tests. It

is also important that you can switch off the loudspeakers quickly

to avoid crosstalk into the headphone. The degree of loudspeaker

crosstalk into the headphones will of course depend on whether you

have open, half -open or closed headphones.

3. As starting points, first choose the following adjustments:

Crossfeed: 3, Angle: 30°, Center Level: -1,2dB.

4. Activate Crossfeed, Anlge and Center. The audio channels will now

be mixed with time, level and frequency corrections calculated pre-

cisely to match what you hear when monitoring over loudspeakers.

You should now compare what you hear with headphones and loud-

speakers. First, whether or not you have the correct width in your

stereo image. If this appears too narrow or too broad with the head-

phone, you have always two ways for further adjustments.

Increase Crossfeed. With this approach more of each channel is

mixed to the opposing side, but the Angle remains unaffected.

Technically speaking, this process changes the interaural level dif-

ference. However, the interaural time difference on the contrary

changes only minimally.
