Loudspeaker comparator
Connecting speakers
With the LSC4S, you can compare up to 4 stereo or mono speaker
sets. To connect mono speakers, leave outputs B not connected and
only use a mono source, connected to input A.
The following speakers can be connected:
• Small - medium sized
• Impedance: 6 - 12 Ω
The following speakers CANNOT be connected:
• 70 V, 100 V speakers
• Active speakers
• Subwoofers
Make sure to connect the plus from the speaker to the plus from
the output and the min from the speaker to the min from the
output. Never connect speakers in parallel or in series.
To compare speakers in an objective way, make sure that:
• All speakers have the same impedance. If not, the volume will
be different and this will influence the perception of the quality.
• Place the speakers at ear height.
• Use cables from LSC4S to the speakers with sufficient diameter
(minimum 1.5 mm²) and keep all cables as short as possible and
at same length.
• Use a high quality source (CD player) with original CD
recording, no copies.
• Choose a dynamic track with good low – mid – and high
frequencies.
