5. OUTPUTS
The HMA120 has a dual amplified output:

Low impedance (4

), for the connection of a speaker or set of speakers with an overall
impedance of 4

. In this case, use the 4

terminals (+ and -) on the back panel OUTPUT
section

High impedance, 70V or 100V, for the connection of a (large) set of speakers with 70V or
100V line transformers, and whose total required power is not greater than the rated power
supplied by the HMA120. In this case, use the 0V and 70V or 0V and 100V terminals of the
OUTPUT section on the back panel
The AUX OUT (38) provides a -6dBV signal level, which is an unamplified copy of the signal
delivered to the OUTPUT terminals. In this way, it is possible to use such output for the connection of the
HMA120 to one or more additional amplifiers in order to manage areas requiring higher power.
6. REMOTE CONTROL PORTS
The HMA120 has two control inputs on its rear panel for its integration with other equipment in a
setup:

REMOTE: allows the connection of a WPm-SR series or WPTOUCH wall control panel for the
remote selection of music sources and setting of the device output volume, using a 0 - 10 VDC
voltage:
o
The selection of sources with the 5-way switch of the wall control panel allows you to select
the music program input among the following options: OFF, LINE1, LINE2, LINE3, MEDIA
o
The volume adjusted with the wall control panel potentiometer affects the global volume of
the HMA120 output (mixing all the active inputs)

MUTE: total mute of the device using an potential free, external contact
