70/100 V Transformer

Installation Instructions

Important Safety Notes

It should be recognised that 100 V-line or 70 V-line speaker systems have the
potential to deliver an electric shock. Install the CXL-80T only in accordance
with these instructions.

In all cases, the external wiring and associated speakers will need to comply
with local electrical regulations for AC voltages up to 100 Vrms (141 Vpeak).

Do not expose the transformer to rain or moisture.

The transformer module must be installed in a safe manner.

Cloud Electronics Ltd. accept no responsibility for hazardous installations.

INTRODUCTION

Speaker Outputs

The CXL-80T is an optional transformer for the 46-80 Multi-Zone Mixer Amplifier, to permit the Mixer Amplifier to directly drive
100 V-line or 70 V-line loudspeaker systems. The transformer is rated at 80 W output, and is mounted internally. Up to four
CXL-80Ts (one per output channel) may be fitted to a 46-80. The outputs are available on the 8-pin 5 mm-pitch screw-terminal
SPEAKER OUTPUTS connector on the host unit’s rear panel.

46-80 Rear Panel

NOTE: unlike some other Cloud multi-channel amplifiers, the 46-80 uses a single output connector for both low impedance and
70/100 V-line operation. Thus it is NOT possible for any channel of a 46-80 to drive both low impedance speakers and
70/100 V-line systems simultaneously. The check boxes below the connector should be used to indicate the standard each output
is set for.
