manual carefully, and keep it in a safe place for future reference.
Features
• The EMX620’s six input channels support a wide
range of audio sources, including microphones,
instruments, and line-level devices. Input chan-
nels 1 through 4 feature lo- and hi-impedance
balanced inputs, with +15 V phantom powering
for use with condenser-type microphones on the
lo inputs, input channel 5 features two line-level
inputs, while input channel 6 features two
hi-impedance inputs for connecting instruments
such as electric-acoustic guitar and electric bass
directly.
• The built-in power amplifier offers a maximum
output of 200 W with a 4
Ω
speaker system,
135 W with an 8
Ω
speaker system, and a limiter
circuit prevents sounds distortion and speaker
damage.
• The 7-band graphic equalizer on the main output
allows you to tailor the sound for each particular
venue and reduce the risk of feedback by attenu-
ating troublesome frequencies.
• Also built-in is a digital effects processor, offering
three different programs for adding reverbera-
tion or ambiance to vocal or instrument sounds,
and remote on/off control using an optional
footswitch.
• External effects can be patched into the system
via the EFFECT OUT and AUX IN jacks, with
effects return level control.
• Separate outputs are provided for connecting
powered monitor speakers, headphones, or a ste-
reo recorder (cassette, DAT, or MD).

■
Channel Section
The channel controls are used to set the EQ,
MONI and EFFECT send levels, channel LEVEL,
and PAD for each channel.
1
HIGH & LOW EQ controls
The 2-band equalizer allows you to boost or cut
the low or high frequency range for each channel.
The frequency response is flat when the controls
are in the center (
▼
) position. Rotating clockwise
boosts frequencies, rotating counterclockwise
cuts them.
The center frequencies are as follows:
HIGH: 10 kHz ±15 dB shelving type
LOW: 100 Hz ±15 dB shelving type
B
MONI control
The MONI control determines the level of the
input signal that is fed to the MONI bus and sub-
sequently the MONITOR OUTPUT jack.
The MONI control is not affected by the chan-
nel’s LEVEL control, since the MONI signal is
sourced before that control.
C
EFFECT control
The EFFECT control determines the level of the
input signal that is fed to the EFFECT bus and
subsequently the onboard effects processor and
EFFECT OUT jack.
EFFECT bus signals are fed simultaneously to the
onboard effects processor and the EFFECT OUT
jack for use with external effects processors.
The EFFECT control is affected by the channel’s
LEVEL control, since the EFFECT signal is
sourced after that control. To send a channel sig-
nal to the EFFECT bus, both the EFFECT and
LEVEL controls must be turned up.
D
LEVEL control
The LEVEL control determines the level of the
input signal that is fed to the MAIN bus, MAIN
output section, and internal power amplifier.
E
PAD switch (1–4 only)
The PAD switch attenuates the input signal by
30 dB. When connecting a line-level source to
inputs 1 through 4, or if a microphone signal is
distorted, use the PAD switch to attenuate the
input signal.

Troubleshooting
The following table describes the possible malfunctions of this demvice, and the appropriate actions to be
taken in each case.
Problem Cause Action
Sound is no
longer out-
put from the
speakers.
The POWER
indicator is lit.
The load on the amplifier of this device
was too great, and the protection circuit
for the amplifier
has operated. Possible
reasons for the excessive load are an
excessive level setting in the channel
control section or main section, insuffi-
cient ventilation, or insufficient load
impedance of the connected speakers.
Please wait. When the device cools off, normal
operation will resume automatically. However,
please check the following three points to prevent
the problem from recurring.
If the level setting is excessive, lower it to the nomi-
nal level. You can refer to the peak level indicators
of the main section when doing so.
If the device is not ventilated sufficiently, refer to
the cautions given at the beginning of this manual
and take appropriate measures to insure adequate
ventilation.
If the load impedance (including a short) is too
low, refer to the chapter on rear panel (page 11)
and change the connections so that the impedance
is correct.
Other
Connections between devices have come
loose.
Inspect the connections, and correct any faulty
connections.
