3. Connections
HTM61 S2
All connections should be made with the audio equipment
switched off.
There are 2 linked pairs of terminals on the back of the speaker.
For conventional connection, the terminal links should remain in
place (as delivered) and just one pair of terminals connected to
the amplifier. For bi-wire connection the terminal links should be
removed and each pair of terminals connected to the amplifier
independently. Bi-wiring can improve the resolution of low-level
detail.

Ensure that the positive terminals on the speaker (marked + and
coloured red) are connected to the positive output terminal on the
amplifier and the negative terminals on the speaker (marked – and
coloured black) are connected to the negative output terminal on
the amplifier. Incorrect connection can result in poor imaging and
loss of bass.
Ask your dealer for advice when selecting speaker cable. Keep
its total impedance below the maximum recommended in the
speaker specification and use a low inductance cable to avoid
attenuation of high frequencies.
