Applications and Accessories
The PULSE PA-40 combines a speaker system, an amplifier, and UHF wireless receiver for a wireless
microphone or a pocket transmitter (handheld UHF microphone supplied). An additional microphone
pack containing UHF beltpack, headset microphone and lavalier (tie clip) microphone is also available,
please order “PA-40 BP/LAV” from your local PULSE dealer.
Power is supplied from a mains socket via the power supply unit provided or via the integrated
rechargeable battery which allows mains-independent operation, the system has an internal charging
circuit for recharging the battery.
To cover larger areas & crowds, several PULSE PA-40 systems can be set up to receive and
reproduce the signal of one single wireless microphone. To do this set all units to the same UHF
frequency and adjust volume controls accordingly. It is also possible to connect the PA-40 to external
powered speaker systems via the audio output MIX OUT.
The system is supplied with a practical shoulder bag and a shoulder strap.
4 Operating the System
4.1 Power supply/recharging the battery
1) For operating the active speaker system via a mains socket and/or for recharging the internal
battery, connect the power supply unit supplied to the jack DC IN (14) and connect it via the mains
cable supplied to a mains socket (100 – 240 V~/50 – 60Hz). If the power supply unit is connected
to the mains socket, the green power LED will light up on the power supply unit.
2) As soon as the power supply unit supplies power to the active speaker system, the battery will be
recharged: The green charging LED CG (13) will flash. For charging, it is not necessary to switch
on the unit with the switch and volume control MAIN VOL (11), however, the unit can be used as
usual during the charging process.
3) When the battery has been fully charged, the charging LED CG will light continuously. In this case,
a mains-independent operating time of approx. 3 hours at maximum volume will be possible, if used at
lower volumes run times of up to 8 hours can be achieved.
4) The battery should be recharged when the red LED LO BAT (12) starts flashing while the unit is
switched on.
5) After operating or after recharging the battery, disconnect the power supply unit from the mains
socket to prevent unnecessary power consumption.
Notes
1. If the active speaker system is not used for a longer period, the battery should be fully recharged
every 2 – 3 weeks to ensure a long battery life.
2. As the rechargeable battery is subject to normal aging, the battery is classed as a consumable item
and covered by a 90 day warranty from point of sale.
3. The charging circuit is matched to the type of integrated rechargeable battery. Replace a defective
battery by one of the same type only – see specifications! Failure to do so will result in damage to the
unit and the battery.
4.2 Positioning & Transporting
For optimum setup the system is best mounted on a stand at a height of 1 – 1.5 m above the ground.
An optional stand “PA-40 STAND” can be purchased from your local PULSE dealer.
For mobile use, e. g. guided tours or outdoor events, the shoulder strap or the shoulder bag supplied
can be used. Fasten the strap to the eyes (1). For operation inside the shoulder bag, put the active
speaker system into the bag in such a way that the sound from the speaker will be radiated through
the mesh side. To access the operating elements and connections, open the lateral flap of the bag
(Velcro fastener).
4.3 Connections for Microphones & Audio Sources
Always switch off the active speaker system before connecting!
1) In addition to the wireless microphone, a cable connected microphone may be used. Connect the
microphone to the jack MIC IN (7).
2) Audio units with a line output (e. g. CD player, cassette recorder, MP3 player or laptop) can be
connected to the jack AUX IN (8). A cable-connected microphone and an audio unit should only be
connected at the same time if the output level can be adjusted on the audio unit; otherwise the volume
ratio between the microphone and the audio unit cannot be altered.
3) For sound recordings, connect a recorder to the jack MIX OUT (9). The output level is independent
of the position of the control MAIN VOL (11).
4) For PA applications of larger zones, connect an additional PULSE PA-40 to the jack MIX OUT (9).
More units can then be daisy chained from the mix out of the second unit etc.
5 Operation
1) Switch on the unit with the on-off switch and volume control MAIN VOL (11). During operation,
the red LED LO BAT (12) will light up. If it the light flashes, recharge the battery as per chapter 4.1.
2) If a microphone is connected to the jack MIC IN (7) or a unit to the jack AUX IN (8), adjust the
desired volume with the control MAIN VOL.
3) If a wireless microphone or a beltpack transmitter is used, switch on the receiver with the on/off
switch and volume control VOL (3). The red LED PW (5) will light up.
4) Leave the wireless microphone or the pocket transmitter switched off for the time being and
use the rotary switch (4) to select a channel which is free and interference-free.
If the green LED RF (6) lights up after the channel has been selected and with the microphone
or transmitter still switched off, interference or signals of other transmitters are received on this
channel. In this case, set the receiver to a different channel.
5) Switch on the wireless microphone or the pocket transmitter and set it to the same channel as the
receiver. The green LED RF (6) will light up to indicate reception of a radio signal.
6) If a microphone is connected to the jack MIC IN (7) or a unit to the jack AUX IN (8), use the control
VOL (3) to add the microphone signal received. If the wireless microphone or the pocket transmitter is
used on its own, advance the control VOL (3) to approx. 2/3 and adjust the volume with the control
MAIN VOL (11).
7) Adjust the sound with the TONE control (10).
