SPL HPm Dual Headphone Amp
SPL HPm Dual Headphone Amp
The output stage of the headphone amplifiers is designed as a push-pull amplifier in Class AB mode. The bipolar transistors share the amplification of the positive and negative half-waves, which produces a higher gain and a higher output voltage than in Class A operation, where only one transistor amplifies both half-waves.
The output stage transistors are thermally coupled and thus run particularly coherently, which contributes to a consistent and stable sound image. The power supply has a buffer circuit with low source resistance, ensuring generous current reserves even when operating low-impedance headphones. Both headphone amplifiers provide individual volume control.
STEREO/MONO/MUTE
The audio signal can be switched between stereo and mono. In the Mute position, the headphone
outputs are muted.
PHASE INVERSE Ø
With the phase inversion switch, the phase of the left or right channel can be inverted (180°).
TIP: M/S – MID OR SIDE?
By using the MONO and the phase invert switch in combination, it is possible to only monitor the
M or S signal. When “Mono mode” and phase inversion is active, only the S signal is played back.
If the phase inversion is switched off, the Mono signal corresponding to the M signal is played back. Separate monitoring of the M and S signals has become a standard for many mixing and mastering engineers.
