TC-5 is a 4 way speaker switch control designed to enable 4 pairs of stereo loudspeaker to be connected
to a Hi-Fi power amplifier and make it possible to control them individually or all 4 pairs together. It will select
the most appropriate series or parallel configuration automatically to suit the number of speaker selected to
ensure a safe load impedance for the amplifier

Features:

• Switch-able between any loudspeaker combination when all 4 pairs of speakers are connected up.
• Power rating 200W music power per channel.
• Quickness and quick connection by screw terminals.
• Stylish strong metal cabinet.
  　

Technical informations:

TC-5 using the parallel and series switching circuit to protect the connected amplifier, regardless of which
loudspeakers are switched on, the amplifier load will not fall below half that of the loudspeakers in use.
For instance, If using 8 ohm loudspeakers the minimum load will be 4 ohms, Nearly all amplifiers will accept
a load of 4 ohms.
Following is the series & parallel switching loading chart using 8 ohms loudspeaker speaker selected
