ifi Pro series iCAN - Tubes and Gain Selection; 3 D Holographic for Loudspeakers (cont.)

iv.
60˚
+: This matrix corrects (’+’) the spatial distortion caused by the recording/mixing/mastering process and adds an
approximate 60˚ to the apparent width of the soundstage. This is close to the ‘wide’ placement preferred by some
audiophiles.
The Holographic circuit for loudspeakers corrects a distortion of the sound eld caused by recording via microphones
and playback via loudspeakers. This sound eld distortion was rst described by Alan Dower Blumlein (the Inventor of
Stereophonic sound) and corrected by EMI in early ‘Stereosonic’ recordings.
However, the original Stereosonic circuit tended to result in a narrower soundstage than if recorded straight and often
overcompensated distortion of the soundstage perspective. iFi’s Holographic systems avoid this and instead, allow an
expansion of the width of the sound stage.
Tip: These modes can also be used to enhance the imaging of recordings that oer poor spatiality.
NOS GE5670 Tubes
New Old Stock ‘Made in the USA’ General Electric 5670 x 2.
Tip: Each GE5670 tube has undergone a special rejuvenation process and the tube circuit is specially-designed for long life.
Combined, the tubes should oer many years of enjoyment.
Gain Selection
0dB (Default)/9dB/18dB.
Tip: Use the lowest gain possible for the best sound. At normal listening levels, the volume control should be around 12 o’clock.
Increase the gain if the 12 o’clock position does not provide satisfying listening levels.
Note: Please be aware that the Pro iCAN can output >10V in Single Ended mode and over 20V in Balanced mode. For comparison,
