Wiring for two pairs of speakers

For larger open plan areas, two pairs of speakers can be used to achieve an even distribution of sound.

A speaker wire (purchased separately) should be fitted between the first speaker and the second,

for both left and right as shown in the diagram. The speakers should be connected in series where

the negative (black) connector of the first speaker is connected to the positive (red) connector of the

second. The negative (black) connector of the second speaker is then connected to the negative

(black) cable to the E120 unit using a connector block, as shown in the diagram. This series method

of connecting two speakers will ensure a high quality and reliable sound performance of the speakers.

Antenna alignment:

An external DAB antenna is recommended, if that is not possible then E120 is supplied with a flexible

indoor antenna which should be aligned vertically as shown below.

Configurable Switches:

There are two small switches mounted on the lower PCB that adjust the audio mode

outputs. After making a switch position change you will need to power down the

E120.

SWITCH 1 OFF – Line output is variable, adjusts with amplifier volume.

SWITCH 1 ON – Line output is fixed at 100%

SWIITCH 2 OFF – Amplifier speaker outputs are in stereo mode with separate left

and right channels.

SWITCH 2 ON – Amplifier speaker outputs are in mono mode with both left and right

channels combined on both speaker outputs.
