Tannoy Mercury V owner manual Connection, Single Wire Mode

CONNECTION V4

Single Wire Mode:

The terminal panels have captive link bars fitted as standard to link the positive and negative HF and LF terminals respectively. These must be removed to Bi-Wire the speakers - see section entitled Connection in Bi-Wire mode. (See fig. 2)

For optimum performance in single wire mode, loudspeaker cable connections from the amplifier should be made to the high frequency (HF) terminals of the loudspeaker:

Connect as instructed above for V1, VC & VR. (See fig. 2)

Bi-Wire Mode:

Please note in Bi-Wire mode that the link bars must be removed. Unscrew the knurled nuts on both the positive and negative HF and LF terminals and remove the link bar and then replace the colour coded nuts, as they will be required to clamp the Bi-Wire cables in place. Retain the link bars in a safe place for possible future use.

Be sure that the amplifier is switched off and then prepare the two sets of cabling for each ‘side’ of the system separately. Measure and cut four lengths of cable, two per speaker.

Label two of the cable lengths Left LF and Left HF (low frequency and high frequency) then repeat this process for the right pair.

If your amplifier is not equipped with separate output terminals for bass and treble information then, at the amplifier end of the cables, twist the Left LF+ (positive) and the Left HF+ (positive) together. Connect these to the amplifier Left channel positive terminal marked + (plus) or coloured red.

Twist the Left LF- (negative) and the HF- (negative) cables together and connect them to the amplifier Left channel negative terminal marked - (minus) or coloured black.

At the loudspeaker end connect the cables labelled Left LF+ and Left LF- to the left hand loudspeaker LF terminals, ensuring that you note the polarity markings on the cable sheathing.

Then proceed to connect the Left HF+ and Left HF- to the HF terminals on the same loudspeaker.

Repeat this process to connect the right hand loudspeaker to the amplifier right channel output, once again ensuring that polarity is correct throughout.

Switch the amplifier on with the volume control set at its lowest setting. Select a favourite source and slowly turn up the volume to a low level. Check that bass and treble information is being reproduced from both speakers - if not, switch off the amplifier and recheck the connections. (See fig. 3)

Bi-Amp Mode:

Bi-Amping extends the principle of Bi-Wiring one stage further. In this connection option separate power amplifiers are used for bass and treble signals in each loudspeaker. Four mono (or two stereo) amplifiers of the same type are required for a stereo pair of loudspeakers. Ensure that the cable links between the loudspeaker terminals are removed and that correct polarity is maintained throughout.

If two stereo amplifiers are used, it is recommended that one amplifier supply bass information to left and right loudspeakers and the other, the treble information. (See fig. 4)
