AC inlet and fuse holder. Use the supplied AC cord to connect the unit to AC mains. Make sure
voltage and frequency stated and set on the unit comply with your local AC supply. The fuse
can be accessed by the small drawer at the AC inlet. To change the fuse, unplug the AC cord
first, pull out the fuse drawer and replace the fuse ONLY with a fuse of SAME voltage and
rating. If the fuse blows again after replacement, hand over the unit to qualified service person­nel.

Stereo Main output. This is a balanced stereo ¼’’ TRS output carrying the main output signal
controlled by (25).

Stereo Main output. This is a balanced terminal block output carrying the same signal as
output (2)

Mono switch for main output. Sums the left and right channel to a mono signal when
pressed.The signal is then available on both the L and R outputs (2, 3).

Maximum level setting for Stereo Main output. This control allows to limit the maximum level
at the outputs (2)/(3) in order to match the connected sound system. Adjustments made on
this control will not be displayed by the output level meter (26). Adjustments shall be made
with a small screw driver. Note that the total angle is 300 degrees; do not apply excessive
force with the screw driver.

Talkover threshold adjustment for Stereo Main output. This controls allow to set the level at
which the talkover is enabled. The amount of damping which is applied once the talkover is
active (DPG) is set by a front panel control (24). Adjustments shall be made with a small screw
driver. Note that the total angle is 300 degrees; do not apply excessive force with the screw
driver.

Record output. This is an unbalanced stereo output carrying the same signal as the main
outputs (2)/(3), but not influenced by the main volume control (25). This is normally used for
recording the output to an external tape, CD or memory device.

Music Mute input. This is a terminal block input which allows to remotely mute the main output
by simply shortening the contacts.

Emergency input. This is an auto-sensing, balanced terminal block input which allows the
connection to an emergency evacuation system. Once a signal is present on this input, the
main output signal will be muted and the emergency message/signal from this input will
become audible instead. Note that the unit can be set to include or exclude the microphone
signals from this muting process, please see section “microphone emergency priority setting”.

Emergency volume control. This control allows to set the level with which the signal fed into the
emergency input (9) will be replayed at the two main outputs (2)/(3).

Priority microphone input “M”. This is a balanced ¼” TRS input with adjustable priority over
other signals by means of the talkover controls (6) and (24). Phantom power can be enabled
or disabled depending on the connected microphone type, see section “microphone phantom
power setting”.

GAIN control for priority microphone input. “M” This allows the sensitivity (input gain) for input
(11) to be adjusted to match different microphone output levels.

MICROPHONE input for CH1/2/3/4/5. These are balanced ¼” TRS connectors, which can
be internally set to either carry phantom power or not, thus these inputs can be used both with
condenser and dynamic microphones. Please see section “microphone phantom power
setting”. The signal of these inputs is controlled by the front panel controls (20)/(21).

LINE input for CH1/2/3/4/5. These RCA connectors provide inputs for line-level signals to
the assigned channels.

SOURCE selector switch for CH1/2/3/4/5. Allows to switch the input source between the
connected LINE signal (14) or microphone signal (13) of the respective channel.

GAIN control for input channels 1/2/3/4/5. This allows the sensitivity (input gain) for every
input to be adjusted, so that sources of different output level can be mixed at properly
balanced levels.

LINE input for channel A (FOH). This is a ¼’’ TRS balanced stereo input specifically designed to
allow the connection of the output of a stage mixer or any other balanced audio source at
larger distance, in order to use the connected sound system for the replay of such source‘s
signal. This is useful in applications where e.g. apart from stereo source replay also live music
is performed over the same sound system, or where a source signal from a different
room/area needs to be replayed. The volume of this input is controlled by a rotary front-panel
control (19). Note that this input is disabled when a connector is inserted into the front-panel
AUX jack (18).

AUX Input for CHANNEL A. This is a 3.5mm Mini-TRS stereo socket which allows to connect
sources like MP3 players etc. without removing the mixer from its mounting position. Once a
plug is inserted, the rear panel balanced line inputs for CHANNEL A (17) are disabled and the
connected source is active.

VOLUME control for channel A. Controls the volume of the signal inserted in the balanced
rear-panel input (17) or the front-panel TRS input (18) respectively.

VOLUME controls for channels 1/2/3/4/5. Control the volume of the signal inserted in the
rear-panel microphone inputs (13) or line inputs (14) depending on the setting of the source
selector switch (15). The maximum attainable volume is adjustable by the rear-panel gain
control (16).

EQUALIZER for channels 1/2/3/4/5. Allows the adjustment of the tonal balance for the
respective input in two frequency bands with an adjustment range of ±12dB.

VOLUME control for priority microphone channel. Controls the volume of the signal inserted in
the rear-panel prirority microphone input (11). The maximum attainable volume is adjustable
by the rear-panel gain control (12).

EQUALIZER

for priority microphone channel.

Allows the adjustment of the tonal balance for the

priority microphone in two frequency bands with an adjustment range of ±12dB.

Talkover Damping Control. This control determines the amount of damping applied to the
program signal when the priority microphone is spoken into. Being fully turned clockwise, once
speaking into the microphone, the program signal is completely suppressed. Being turned fully
counter-clockwise, the talkover function is off. Any position in between allows seamless adjust­ment of the amount of damping applied to the program signal. The threshold level from which
on this function is enabled can be set by the rear panel sensitivity level control (6).

A. Microphone phantom power setting

While most applications will work well with dynamic microphones, on certain occasions the use of a
condenser microphone may be required. To supply the necessary voltage to the microphone, the
IPM-1610V2 provides an internal option to activate phantom power, separately for the priority micro­phone (microphone channel “M”) and for all other microphone inputs (CH1...CH5). Please note that
the phantom power settings for channels 1-5 can only be made globally, not individually. Open the unit
and locate the rear PCB as shown above. Set the jumpers as required.

B. Microphone emergency prirority setting

In the case of an external emergency signal muting the unit’s outputs, an internal jumper can be set
to either mute the connected microphones (”off”) as well or to to keep them active (so that aside of a
emergency message broadcasted, additional instructions can be given by a local microphone - “on”).
To make the setting, locate and set the jumper on the rear PCB as shown above.

Operation

A. Connections

For connecting this unit to AC mains, please note:
Check whether the AC mains voltage and frequency is the same as this product is specified for (see

rear panel of product). Whenever the specified voltage or your AC plug should not match the local
conditions, do NOT plug the AC cord into the wall outlet and contact you dealer immediately.

Do not operate this unit without the line cord earth ground connected. To do so may increase the
risk of electric shock and increase line cord conducted emissions.

For making audio signal connections, always remember that good and reliable connections are a
basic requirement for good sound and reliable operation. Bad soldering of cables can result in inter­mittent audio signals or temporarily lost ground connections, hence always use good cables. In case
of doubt about making proper connections, please see check the standard pin assignments required
for proper operation in the following section of this manual.

B. Powering up

Following a proper power-up sequence protects your equipment – specifically speakers – and your
ears. Follow the below procedure:

Turn down all output volume controls of any equipment in your audio system.
Switch on your audio sources first (Tuners, CD Players, PC’s with soundcards, Tapedecks, etc.)
Switch on the audio mixer
Switch on any audio processor between the mixer and the amplifier(s) [if any].
Switch on the amplifier(s).
Turn up the audio level on your sources if such controls are provided.
Set the audio output of your mixer to a low level.
Set the audio output of any audio processor between the mixer and the amplifier(s) to a medium
level [if any such processors].
Turn up the volume controls of your amplifier(s) slowly.
Make adjustments to all volume settings as needed.

For switching off, follow the inverse sequence – always switch off your amplifier(s) first, then any
processors between mixer and amplifier(s), then the mixer, then the sources.

C. Use

Apart from using good equipment, good sound comes from using it correctly. Level setting mistakes
are one of the common reasons why even good equipment may not perform as desired. For setting
levels, please be reminded that two guidelines need to be followed:

Avoid distortion by leaving some headroom. Never overrun any audio-equipment’s inputs. Level
meters and displays allow you to make sure that signals do not enter critical levels.

Avoid unnecessary amplification by using as little attenuation as possible. For example, if you turn
down the input gain of a mixer to minimum, and then increase the main output of the mixer to maxi
mum to drive your amplifier properly, you will create unnecessary noise, as you first dispose of some
already existing signal level, and then later apply amplification (tainted with noise) to make it up.

Obviously, these two requirements are marking a levelling window that the operator must match to
achieve a good sound with as little distortion and noise as possible.

WARNING - HEALTH RISK

Excessive volume levels on headphones or other sound systems may cause hearing
damage. Always turn the volume control to minimum when you switch the unit on, and
avoid prolonged exposure to sound pressure levels exceeding 90dB.

Maintenance and warranty

While we have chosen the best components to make this product as rugged and reliable as possible,
some parts in audio products (potentiometers, faders, switches) are subject to wear which is a
matter of operation cycles, and not of time. While providing a full time-based warranty according to
the country’s of purchase requirements on the function of the electronic circuitry, we hence have to
limit the warranty on such electro-mechanical parts to 90 days from the date of purchase.

In many cases, malfunction of electro-mechanical parts occurs due to dust contamination, which may
require cleaning of such parts. As the inside of such parts is not accessible, a common practice is to
use cleaning fluids in the shape of sprays. Please be reminded that many of such fluids contain chemi­cals which may wash away the dust but at the same time corrode or damage contact surface and
may cause cosmetic damage to other parts. We hence explicitly exclude any claims for exchange of
damaged part due to mechanical or chemical impact.
