<p>The board (1) has a pre-listening circuit for pre-listening sound signals of channels (2, 3) by a headphone of a player, where the sound signals are formed as output signals of the headphone. The sound signals are passed to an amplifier output (4) in parallel without amplification through a passive sound filter (10) and a passive cross fader (11) and to a headphone output (5) via switches (6, 7) of the channels, where the switches are provided for selecting the channels, and an amplifier is connected to the amplifier output.</p> |
