USER MANUAL - VMA1240 INSTALLATION MIXING AMPLIFIER
MUSIC source selector. This rotary 4-psotion switch allows to choose any of the 3 rear-side
Line inputs (16) to be the music source, or the internal media player. Additionally, a front-side
3.5mm TRS input (34) can be the source, which automatically replaces the Media Player
signal if a plug is plugged into the socket (34).
AUX (Line3) Front-side socket. This 3.5mm TRS jack has an auto-switching function which
replaces the internal media player signal automatically once a jack is plugged into the socket.
This is mainly suitable for MP3 players, smartphones etc. Plug the source into this socket and
set the selector switch (33) to MediaPlayer.
MUSIC volume control. Controls the level of the source chosen via the MUSIC source selector
switch (33). Note that the microphone volume controls (26), the chime volume control (32)
and this MUSIC volume control are all summed before the overall volume is adjusted by the
MAIN volume control (36).
MAIN volume control. Allows to set the level of the MAIN output signal, which is composed of
the music signal selected by the MUSIC source selector switch and volume control (33 & 34),
the microphone signals determined by its relative controls, plus the Chime signal.
MAIN Equalizer. Allows the adjustment of the tonal balance for the MAIN output signal in two
music-specific frequency bands with an adjustment range of ±10dB.
MAIN level meter. Indicates the MAIN output level in 5 steps via relative LEDs. Note that the
meter only indicates the signal strength after the MAIN volume control (36), but does not
account for level reductions set by the rear side maximum volume control (6). If the level meter
indicates full volume but the output appears low, check the setting of the rear-side maximum
volume control (6) first.
ZONE source selector switch. Determines the source for the ZONE signal. Available choice are
MAIN, Line1 and Line2. This signal is available at the Preamp/Zone output (10)
ZONE volume control. Allows to set the level of the ZONE signal, which is determined by the
zone source selector switch (39). This signal is available at the Preamp/Zone output (10).

the unit off when not in use.
SD Card slot. Insert a FAT32-formatted SD card of max 16GB with a one-level folder structure
for replay of MP3 files here. If both a USB memory stick is inserted into (43), and an SD card
is inserted in (42), the last inserted media will be given priority.
USB memory socket. Insert a FAT32-formatted USB memory stick of max 16GB with a one-
level folder structure for replay of MP3 files here. If both a USB memory stick is inserted into
(43), and an SD card is inserted in (42), the last inserted media will be given priority. Note: this
socket does NOT support USB hard drives, both for memory size and power requirements.
Media player display. Shows track/folder information, time information, play status, replay
mode settings and play sequence settings. Details are described under items (55...65)
