Either an 8 Ω speaker or amplifier (600 Ω min.) can be connected to the mes-
sage output jack of the Voice Unit.
If a low message output volume is required connect a speaker directly to the
message output jack and set the Voice Unit front panel line/speaker switch to
the speaker symbol.
To amplify the message output volume or make more than one speaker con-
nection, connect an external amplifier to the message output jack. Both bal-
anced and unbalanced amplifiers can be connected, however a balanced
amplifier is recommended for better sound quality and because the overall
interconnection cable length is longer. Set the line/speaker selector switch to
L when connecting to an amplifier.
