1.4. General information
The PROLOOP DCCplus amplifier has been designed for use in professional venues where high reliability and
safe operation are essential. The 100% short-circuit-proof amplifier with its extremely stable output power meets
these requirements.
1.5. How it works
The induction loop amplifier generates an alternating electromagnetic field around the loop cable. The loop con-
sists of an insulated wire, which is usually laid singly (or doubly) along the side of the room. When the hearing-
aidwearersetthehearingaidtothe“Tposition”,voltageisinducedintotheTcoil.Thisvoltagedependsonthe
amplifier’s input signal. Now the signals are amplified by the hearing aid and converted into sound. The alterna-
ting electromagnetic field inside the loop allows the hearing-aid wearer to move around freely in the room and to
receive the voice or music signals as high-quality, pleasant sound.
1.6. Notes on safe operation
This device complies with all the necessary EU directives and bears the CE seal of approval.

Tips
1. Before beginning to install the device, you should be sure to check the area for any magnetic
interference. Such interference can have a negative affect on the operation of the device or
make it impossible altogether. Interference can be caused by transformers, power lines, rein-
forced concrete or floor heating systems.
2. If the loop is to be installed in a pipe, then make sure that the pipe is made of plastic.
3. Do not lay any input signal cables parallel to the loop wire.
4. Avoid using dynamic microphones inside the loop. Always chose symmetrical electret or capa-
citor microphones to prevent acoustic feedback.

2.1 Cable cross section and wire diameter
The best audio quality can be reached if the DC (direct current) resistance of the induction loop is between 1
and 3 Ohm. The DC resistance depends on the wire diameter and the wire length. Please follow the steps
below:
1. Calculate the lenght of the loop wire. The wire lenght depends on the size of the induction loop.
2. Use the figure below to get the allowed wire diameter.
Example:
The wire lenght in a rectangular room with a width (W) of 10 m and a length (L) of 30 m is 80 m. According to
the figure below, the wire diameter must be between 0.77 and 1.34 mm. This corresponds to a cable-cross-
sectional area of 0.5 mm² and 1.5 mm².
You can use AWG 20 wire or a wire with a standard diameter of 1.00 mm (cable-cross-sectional area: 0.75 mm²).
Note
The inductive loop system works correct if the DC (direct current) resistance is between 0.5 ohm and
3 ohm.
2.2 Connecting the induction loop
Connect the ends of the loop wires to the terminals (28) on the rear of the amplifier.
Please note the following information

tom voltage. If you want to alter the standard setting please switch off the amplifier and set the switches on the
desired positions. After setting the switches please switch on the amplifier again.
2.4 Automatic Gain Control (AGC) / Limiter
2.4.1 General information
The automatic gain control (AGC) keeps the level of the audio signal on the connected induction loop constant.
The limiter makes sure that audio signals with a strenght of more than 0 dBV are not sent to the connected indu-
tion loop.
2.4.2 Switching the desired function on
Use the AGC/Limiter switch (24) to switch between AGC or Limiter function. If one function is set the other func-
tion is disabled.
AGC
AGC LIMITER
2.4.3 Setting the AGC range
You can set the AGC range with the AGC control regulator (25).
The correct AGC range depends on the audio input signals and the perceptions of the users of the connected
induction loop. If you set the AGC range too wide, soft sounds (e.g., undesired ambient noise) is amplified. If you
set the AGC range too narrow, desired soft sounds are lost.
2.5 Frequency range
You can set the frequency range with the 10K/5K switch (23).
To reach the most optimal results, set the switch on 5K position if the audio inputs contain speech.
If the audio inputs contain background music, set the switch on 10K position.

2.6 Voice activation
The voice activation (VOX) of audio input 2 can be switched on and off with the MIX/VOX switch (26).
If the switch is set to VOX, audio signals of input 2 override the audio signals of input 1. The audio signals of input 1
and input 2 are mixed if the switch is set to MIX.
2.7 Using the priority input (22)
You can use the priority input to connect the induction loop amplifier with a alarm system or a PA-system. The
priority of the priority input is higher than the one of the audio inputs. The signal on the connected induction loop
is replaced with the signal of the priority input if a signal is received at the priority input. Please use the volume
control to set the volume of the audio signal which the priority input sends to the connected induction loop.
Important note
Put the safety bracket on the priority input to make sure that it is not possible
to touch the priority input.

3 Setting up a LOS loop system with PROLOOP DCCplus
If you want to set up a LOS loop system you need two of the PROLOOP DCCplus. The first amplifier will be the
master unit and the second amplifier will be the slave unit.
3.1 Master and Slave configuration
- To define the first amplifier as Master amplifier the Master/Slave switch must be set on Master position.
- The second amplifier must be defined as Slave amplifier by setting the Master/Slave switch on Slave position.
Note
The slave amplifier can only send the signal that it receives from the master amplifier to its induction
loop. The audio inputs and the priority input of the slave amplifier are disabled.
3.2 LOS induction loops
The optimal designs and configurations are always dependent on the venue details, i.e. the floor plans and the
sizes of the rooms serviced, the number of internal induction loops and the demands made on low overspill.
To determine the corresponding values for the »tailored« low-overspill layout and the optimal level adjustments
in each case, it is necessary to use complicated calculation and installation methods. That’s why we recommend
that you use the services provided by HUMANTECHNIK. We support architects, technicians and installation ex-
perts qualified in the planning of LOS installations.
3.3 Installation of the induction loop
To use a LOS system, the induction loop must be installed in a special way. In detail, two separate loops are
used (master/slave), which consist of eight-piece segments lined up one after the other. The exact proportions
and the exact number of segments depend on the demands made on low overspill as well as the size of the
room. The smaller the segment, the smaller the overspill will be.
The master loop is laid over the entire area to be serviced. The slave loop is always one segment shorter than the
master loop and doesn’t begin until after the first segment half of the master loop. The individual segment lengths
should correspond to the distances between the seating rows.
We recommend using a single-strand cable, e.g. H07V-K or the copper ribbon cable (A-4937-0). Please refer
tosection“2.1Cablecrosssectionandwirediameter”fortheneededcablecrosssectionofthesingle-strand
cable.
3.4 Advantages of a LOS induction loop design
- No loss of field strength in the centre of the induction loop
- No horizontal overspill
- No signal holes inside the loop

3.7 Adjusting the amplifiers
In order to adjust a LOS system, you will require a field strength gauge, e.g. the FSMplus (A-4292-0).
1. Before you switch on the amplifiers, turn all the dials as far to the left as possible.
2. Plug in the power cords supplied with the amplifiers and switch the master amplifier on. The power supply
indicator (1) should now light up.
3. Before you adjust the line level, don’t forget to apply a test signal to the corresponding input. We recommend
using our test CD, which comes with the FSMplus (A-4292-0).
Use a 1kHz sine signal (track 3 on the CD) and set the volume control (master fader) on the mixing desk or
the audio amplifier as it is normally used at your events.
4. Adjust the input sensitivity regulator (6) of the LINE IN input used so that the control indicators (2) on the front
panel of the device lights up.
5. Turn the master power regulator (12) to the central setting. The control indicator (3) on the front panel should
now light up.
6.SettheFSMplusto“Norm”and“0dBscale”andholditverticallytotheinductionlooplevel.Theidealheight
depends on what the induction loop system is being used for; typically, this might be 1.20m (for seated au-
diences) or 1.70m (for standing audiences).
7. Check the average field strength by running diagonally over the induction loop area and determine the aver-
age of the values indicated. The average value has to measure 0dB (±3dB).
If you do not obtain this value, adjust the corresponding control until this value is reached. Please note that
every time you cross a cable, the field strength will drop briefly. This is normal as long as only one loop is in
operation.
8. Once the master amplifier is adjusted, switch off the master amplifier and disconnect the induction loop.
9. Now switch on the master and slave amplifier and set the slave amplifier up as discribed above.
Important: Do not alter any of the controls of the master amplifier.
11. If you have set up the slave amplifier, switch the master and slave amplifier off.
12. Re-connect the induction loop of the master amplifier.
13. Switch on the master and slave amplifer, again.
14. For the final check, use a normal audio signal, such as music or voice via the microphone and check the
field strength with the FSMplus. The value should read 0dB (±3dB) in the signal peaks.
If you do not read these values, repeat the measurement process starting from Step 3 and set the controls
higher than for the first test.
15. If the values lie within the stipulated range, the amplifiers are set to the ideal levels. Use the headphone jack
of the FSMplus to evaluate the sound of the signal with a pair of headphones.
