INPUT: BALANCED

Each channel uses a separate 2-pin, 5 mm-pitch screw-terminal connector. Observe loudspeaker polarity: always connect all

'+' terminals together, and all '-' terminals together.

OUTPUTS

100/70 V line loudspeakers will generally include a tapped transformer with selectable power settings. When connecting

large numbers of loudspeakers, always choose the correct tapping for the volume required in the physical area where the

loudspeakers are fitted: e.g., speakers in quiet corridors will need a much lower power setting than those in noisy public areas.

The total power rating of all the loudspeakers connected to a single amplifier channel should not exceed the maximum power

that the channel is intended to provide (see section on "Power Sharing" on page 5) and should never exceed 500 W under

any circumstances.

Each channel has a switchable 65 Hz hi-pass filter, selected by rear panel DIP switches. Programme material with high levels

of low frequency may saturate the loudspeaker transformer cores, causing unpleasant distortion. We recommend that the

filters are left in their factory setting of ON (switches down) if the relevant channels are being used for loud music. It may be

possible to switch the filters OFF for other types of programme, but this should be assessed by listening tests. (Note that on

the CV6160, switches 7 and 8 are not used.)

The maximum volume in each area can be adjusted with the preset LEVEL controls: each amplifier channel has its own control.

Input routing

In common with other Cloud power amplifiers, each amplifier channel can either be fed with a signal from its own input (the

factory default setting), or with the signal feeding another channel. This allows the same input signal to feed several channels

without the need for input connectors to be wired in parallel. CV Digital models with fewer channels are obviously restricted

in the range of routing options available in comparison with models with more channels.

The rear panel INPUT ROUTING DIP switches are used to select input source for each channel, except Channel 1. The factory

default setting is with all switches UP, which connects the input of each amplifier channel to the same-numbered input

connector, as indicated on the upper row of numbers. Setting a switch DOWN parallels the input of that amplifier channel with

the input of the amplifier channel indicated below the switch.

Notes:

•

Switch 1 is inoperative on all models

•

Switches 7 and 8 are inoperative on model CV6160
