System 2013

The System 2013 PLL enables the successful integration of people with hearing problems
in schools and universities, at the workplace and during leisure activities.

The design and control details have been optimally adapted to this target group.
Operation is simple and easy to learn. The units are small, light-weight and inconspicuous.

Units

• Transmitter SK 2013 PLL for the speaker

• Receiver EK 2013 PLL for the hearing impaired

Operating principle

The speaker, e.g. the instructor, wears the Transmitter SK 2013 PLL. The hearing
impaired person wears the Receiver EK 2013 PLL. Headphones or a connecting cable to
hearing aids can be connected to the EK 2013 PLL. The student can now hear the
instructor as if he/she were sitting directly next to him/her - without wires and with
retained freedom of movement. For the time during which the instructor speaks, the
surrounding noises are considerably reduced. If the instructor is not speaking, the hearing
aid or the microphone built into the EK 2013 PLL is completely effective; now fellow
students can be heard. Yet the dialogue between the instructor and the student is always
given priority.

The System 2013 PLL also remains a dependable aid under difficult conditions. The
transmitting output reaches over great distances. Loud secondary noises and poor room
acoustics can be faded out with the use of the additional microphone MKE 2013 on the
Transmitter SK 2013 PLL. The wide range of accessories allows connection of the
receiver to nearly any type of hearing aid; the connection to the hearing aid can be either
electrical or inductive.

2.4

SK 2013 PLL
or EK 2013 PLL

The Transmitter SK 2013 PLL and the Receiver EK 2013 PLL are supplied with current
by attachable RECHARGEABLE battery packs, type BA 2013. These battery packs are
charged over night separately or in conjunction with their unit in the Dual Charging Unit
L 2013. One battery pack has sufficient power for a normal working day (up to 12 hours).
It is completely recharged over night.

Standard (non-rechargeable) battery packs allow operation far from an electrical system
(maximum operating time: over 40 hours). They replace the rechargeable battery packs.

Common characteristics for transmitter and receiver

• up to 40 hour operating time, interchangeable standard and
rechargeable battery pack

• built-in microphone in transmitter and receiver

Frequency selection

D

Setting channels on transmitter and receiver

The transmission frequencies are set with the rotary switch (D) on the transmitter and
receiver. The assignment of a switch position to a frequency is listed on the back of the
unit on the information plate. Depending on the model, up to 16 frequencies are available.
This allows multi-channel operation, e.g. in schools.

Important information:

• The transmitter and receiver of one transmission unit must be
set to the same frequency!

• One transmitter can be used with several receivers set to the same frequency.

• One receiver cannot be used with several transmitters set to one frequency! This

type of incorrect setting can be noticed from crackling and chirping noises at the receiver.

Receiver EK 2013 PLL

3.5 mm dia. Stereo jack
High-level output (2 x 0.7 V / 32 Ω)

2.5 mm dia. Stereo jack
Low-level output (2 x 3 mV / 2 kΩ)

Characteristics

• Up to 16 PLL-controlled frequencies

• Highly visible indicator lamp for all important functions

• Child-proof due to lockable cover of adjustment elements

• Integrated automatic fade-in feature

• Built-in microphone. The receiver becomes a hearing aid

if required. - even without additional accessories -

Connection possibilities on receiver EK 2013 PLL

There are two stereo cinch jacks on the left side of the unit: a large jack with 3.5 mm dia.
and a small jack with 2.5 mm dia.

Only stereo cinch plugs may be inserted into the two jacks! Mono plugs lead to
malfunction or short circuit. Mono headphones must be equipped with stereo cinch plugs.

Integrated antenna

In both jacks the inserted cable is simultaneously used as an antenna. Only use original
Sennheiser cables!

Operation on hearing aid with audio input

The small jack (2.5 mm dia.) supplies the output signal for a hearing aid with an audio
input. Hearing aid dealers carry suitable connection cables.
(also see „CABLES“)

Operation on hearing aid without audio input

The „Tele-Loop“ ETZ 1011 or the Induction Disc EZI 120 for hearing aids without an
audio input is connected to the large jack (3.5 mm dia.).

Operation with headphones

Stereo headphones (impedance > 32 Ω) are connected to the large jack.

2.8

M

S

Lockable cover on receiver

In order to reach the operating elements, a slide (S) is located on the right side of the unit.
This protects the operating elements against unauthorized or accidental use. It is secured
with a set screw (M), which is screwed in completely in order to open the slide.

After removing the slide two potentiometers are accessible:

• The lower potentiometer (P1) adjusts the receiver volume, i.e. regulates the volume
of the signal from the speaker.

• The upper potentiometer (P2) adjusts the basic volume of the built-in microphone.

Automatic fade-in and microphone adjustment

The receiver is equipped with an automatic fade-in feature. The connected hearing aid
microphone or the microphone built into the receiver are turned down for the duration
of speech transmission. This enables the signal of the speaker to be given preference at the
wearer of the receiver.

In addition, the automatic fade-in is complimented by a speech filter. As a result,
disturbing noises (doors banging etc.) do not trigger the automatic fade-in feature.

The automatic fade-in and the basic volume of the faded-in microphone can be set
separately.

Setting automatic fade-in

This adjustment is made exclusively by the hearing aid dealer!

An adjuster (E) for the reduction depth of the automatic fade-in is located at the top behind
a hole in the housing. It can be turned with a 1.6 mm dia. screwdriver. Turning clockwise
increases the reduction depth of the connected hearing aid microphones.

Switching automatic fade-in and built-in microphone on/off

This adjustment is made exclusively by the hearing aid dealer!

Two toggle switches (S1/2) are accessible in the unit between the potentiometers for
switching on the automatic fade-in and microphone. They can be actuated with a small
screwdriver (2.6 mm).

• If the switch (S2) is tipped toward the back of the unit, the automatic fade-in
feature is switched on.

• If the switch (S1) is tipped toward the upper side of the unit, the built-in microphone
is switched on.

(The EK 2013 PLL is delivered with this setting).

Indicator lamps on the receiver EK 2013 PLL

l1

l2

Two LED indicator lamps are located on the front of the unit.

Automatic fade-in, green led

L1 indicates that the acoustic signal is being correctly transmitted. If it lights up, the
automatic fade-in feature is activated. The transmission path has preference over the
surrounding noises transmitted by the built-in microphone.

In addition, L1 also serves as an adjustment aid for the microphone sensitivity at the
Transmitter SK 2013 PLL. (Also see Page 14)

Squelch and battery check, red led

L2 has the dual function „squelch indicator“ (activated squelch) and „LowBat“
indicator for battery check with tendency recognition:

• constant red light Squelch switched on = no reception

• flashing red light slow flashing: The battery voltage is dropping!

rapid flashing: The battery voltage is no longer

Both indicator lamps are arranged on the front of the receiver so that they can also be
dependably seen over a greater distance by the person equipped with the transmitter.
In this way it is easy to ascertain whether the speech connection exists.

25 cm

The 3.5 mm dia cinch jack (B2) is available for the connection of high-level sound sources,
such as tape recorders, TV and Hi-Fi components.

The connection cable of the connected additional microphone MKE 2013 acts as an
antenna. If the additional microphone MKE 2013 is not used, the included additional
antenna must be inserted in the microphone jack.

Indicator lamps

The transmitter is equipped with a red indicator LED (L3) for monitoring the battery
output. The end of the operating period is announced with flashing approx. 15
minutes before the end of operation, so that there is sufficient time to replace the
RECHARGEABLE or standard battery pack.

2.12

R

Setting microphone sensitivity on transmitter SK 2013 PLL

The microphone sensitivity should be set high enough on the regulator (R) that, on the
one hand, the green LED on the Receiver EK 2013 PLL does not go out during normal
speaking and, on the other hand, low enough that normal surrounding noise does not
activate the LED display.

The optimum setting is usually between 5 and 7.
