Functional Description
The IPA200 is a convection-cooled stereo installation amplifier with a flexible input section to adapt it
to both stereo and dual mono applications with low-impedance speaker systems from full range to
limited frequency response,. The flexibility of the inpout section makes the IPA200 the right choice for
both full range background music systems as well as speech-range paging systems, both in main and
zone applications.

AC inlet. Use the supplied AC cord to connect the unit to AC mains. Make sure voltage and
frequency stated on the unit comply with your local AC supply.
Fuse drawer. To change the mains 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.
Speaker Outputs. Connect your speakers to these outputs. Note that these are low-impedance
outputs, not suitable to connect speaker with built-in 100V line transformers. Make sure that
the speakers or any combination of speakers have a minimum nominal impedance of 4 Ohms.
Avoid any short circuits between the plus and minus poles of the outputs, and be aware that
these outputs may carry voltages which represent a risk of electric shock. Consequently, only
connect your speakers when the unit is switched off.
Through connector. This connector carries the same signal as fed into the internal amplifier
blocks of the unit. This means that in case the switch (13) is set to “Stereo”, the through
connector (4) will carry the input signals of channel A and B independently, while in case the
switch (13) is set to “Parallel Mono” both through connectors will carry the input signal of
channel A.
Balanced channel A and B inputs. These are stereo inputs, which are internally summed to
mono. If the signal is alread a mono signal, or just one channel of a stereo signal, the L socket
shall be used for channel A and the R socket for channel B. Providing a stereo input is useful if
your feeding source is stereo but you wish to use it for a mono speaker zone. This way, the
IPA200 can for example be used as a regular stereo amplifier by feeding a stereo source’s
two outputs into channel A’s L socket and channel B’s R socket, and setting the switch (13) to
“Stereo”. The IPA200 can also be used as a dual mono zoner being fed from one stereo
source, with connecting the source to channel A’s L and R inputs, switching (13) to “Parallel
Mono” and then being able to adjust the levels for both outputs independently.
Balanced plug terminal channel A and B inputs. Same function as (5) with a standard 3.5mm
“Phoenix”-style plug terminal socket.
Unbalanced channel A and B inputs. Same function as (5) but unbalanced configuration with
RCA connectors.
HP (High Pass) Filter on/off switch. Engages or disengages the internal high pass filter. Engaing this filter can help to remove low frequency energy from the output signal, which can help
if the connected speaker system consists of speakers with limited low-frequency response like
very small cabinet speakers or open-back ceiling speakers. The roll-off frequency can be
chosen via switch (9).
HP filter roll-off frequency selector. Switches between a 40Hz and a 100Hz roll-off point in
case the switch (8) is engaged.
Equalizer. Allows the adjustment of the tonal balance for the channel A and B output signal
independently in two music-specific frequency bands with an adjustment range of ±12dB.

Maximum level setting. This control allows to limit the maximum level of channel A and B independently in order to match the connected sound system. Adjustments made on this control
will will limit the adjustment range of the front-panel volume controls (14). Note that settings
shall be made with a small screw driver; the total angle is 300 degrees; do not apply excessive
force with the screw driver.
Front volume control enable/disable switch. In certain installation situations, it may be sensible to avoid operators being able to change volume settings. Pressing this switch will disable
the front volume controls (14), making all level adjustments only depending on the rear-panel
maximum level controls (11).
Operation mode switch. Determines the signal routing inside the unit between two options.
Either the Channel A and B input signals are routed independently to the internal amplifier
blocks A and B (setting “Stereo”) or only the channel A input signal is routed to both internal
amplifier blocks A and B (setting “Parallel Mono”).
Front volume controls. Provided the switch (12) is engaged, these controls determine in combination with the rear maximum level setting controls (11) the total volume for each channel.
If the switch (12) is not engaged, these controls are disabled.
Output level meters. Display the output level.
Power indicator. Indicates whether the unit is switched on or off.
Power switch. Switches the unit on and off.

Operation
A1. Connections: AC
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.
A2. Connections: Input signals
Good and reliable connections are a basic requirement for good sound and reliable operation, hence
always use good cables. In case of doubt about making proper connections, please see check the
standard pin assignments required for proper operation shown below
A3. Connections: Speaker cabling
The choice of suitable speaker cables is an essential point of amplifier installation. Speaker cables,
specifically long ones, can significantly contribute to the load impedance of the amplifier, thus reducing the power output and turning some of the output power into heat instead of delivering it to the
speakers. The most important aspect is to keep cables as short as possible and to choose a sufficient
copper cross-section, with maximum length values as per below:

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 this unit, and set it to the desired audio source
Turn up the audio level on your sources if such controls are provided.
Set the MAIN and ZONE volume controls of this unit to a low level.
Make adjustments to all volume settings as needed.
For switching off, follow the inverse sequence – always switch off this unit first, then the connected
audio 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.
