100/70 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-46T 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.

CXL-46T Installation Instructions v1.02

INTRODUCTION

The CXL-46T is an optional transformer for the 46-120 and 46-120MEDIA Multi-Zone Mixer Ampliers, to permit the Mixer
Ampliers to directly drive 100 V-line or 70 V-line loudspeaker systems. The transformer is rated at 120 W output, and is mounted
internally. Up to four CXL-46Ts (one per output channel) may be tted to a 46-120 or 46-120MEDIA. The outputs are available on

the 8-pin 5 mm-pitch screw-terminal SPEAKER OUTPUTS connector on the host unit’s rear panel.

Speaker Outputs

NOTE: unlike other Cloud multi-channel ampliers, all 46-120 models use a single output connector for both low impedance and

70/100 V-line operation. Thus it is NOT possible for any channel of a 46-120 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.

FITTING THE CXL-46T TRANSFORMER

The CXL-46T transformer is a toroidal type, and is supplied pre-terminated with 2-pin and 3-pin connectors as shown:
