8
ENGLISH
wf-u24 User manual
2. VOLUME-A:
It adjusts audio level in A balanced output (11).
3. RF-A:
When lit, this LED indicates the receiving on Channel-A. If RF-A is off, it means that
there is no signal from the transmitter; if ashing, it indicates that there are interfer-
ences or RF signal is low. In these cases we recommend using one of the other four
available frequencies.
4. POWER LED:
Indicates that the receiver is ON.
5. RF-B:
When lit, this LED indicates the receiving on Channel-B. If RF-B is off, it means that there
is no signal from the transmitter; if ashing, it indicates that there are interferences or
RF signal is low. In these cases we recommend using one of the other four available
frequencies.
6. VOLUME-B:
Adjusts audio level in B balanced output (10).
7. ANT-A:
Receives A-Channel radio signal.
NOTE: For proper operation, the antennas must be angled 45° towards the
outside. Never cover the antennas during use.
8. ANT-B:
Receives B-Channel radio signal.
9. MIX OUT:
This line-level unbalanced output with ¼” jack contains both A and B audio signals,
each with level adjusted according to VOLUME A and B knobs at points (2) and (6).
10. BALANCED OUT B:
It is the B-channel line-level balanced output with XLR connector, whose level is adjust-
ed by VOLUME B knob (6).
11. BALANCED OUT A:
It is the A-channel line-level balanced output with XLR connector, whose level is adjust-
ed by VOLUME A knob (2).
12. CHANNEL B:
It selects B-channel operating frequency. There are 4 different frequencies and can be
selected by moving the four switches according to following code:

available. Refer to the instructions provided at previous point.
14. DC INPUT:
It connects the unit to the supplied 17Vdc – 300mA power supply.
5.1. Receiver Operation
POWER CONNECTION:
Plug the supplied adapter into a 230-240V outlet and power cord to the DC INPUT
connector (14).
AUDIO OUTPUT CONNECTION:
You can use the two balanced outputs (10) / (11) if you want to separate the two audio
signals, or you can use the unbalanced mix output (9) if you don’t have a mixer, and
want to use the internal mixer.
POWER ON:
Press POWER on/off (1). POWER Indicator (4) will light, it means receiver is under nor-
mal working status.

6. HANDHELD MIC (WF-U24HH and WF-U24HP models)
1. GRILL:
Protects microphone capsule. Do not remove this
cap to prevent damage to internal components.
2. LED:
This LED lights up briey when you turn on the mi-
crophone. Under normal operating conditions - with
switch (2) in standby or ON position and batteries in
normal conditions, this LED does not light. It ashes
when batteries charge level is low and must be
replaced.
3. ON/OFF SWITCH:
It has 3 positions: when it’s all down, transmitter is
off. When it is in central position, the transmitter is
on but audio is disabled; nally, when it’s all up, the
transmitter is working and the audio is active.
NOTE: Standby central position allows the unit to transmitter without audio.
This option is important to prevent interference in the receiver due to the
absence of a radio transmitting signal. It is, therefore, suggested to ALWAYS
use this standby position when you temporarily don’t sing or play but wire-
less microphone is connected to an audio system (e.g. during a pause in a
show). You can move the switch to OFF position (all down) only when you are
sure that the sound system volume is low.
4 BATTERY SLOT:
Batteries are housed inside the transmitter. Use 2x 1.5V AA type batteries paying atten-
tion to their polarity.
5 BATTERY COVER:
For battery replacement follow the instructions below:
fApply a slight pressure at the top of the door (5) and pull down. Remove the cover.
fInsert or replace the batteries in the compartment, observing the +/- polarity marked
on the bottom.
fReplace the cover on the bottom of the battery slot.
fPush up the cover of the microphone in order to completely close it.
6 DIP-SWITCH:
This multi-switch allows you to choose one of the four available operating frequencies.
In order to work properly, please correspond with the channels combinations of receiv-
er (12) & (13).

10. WF-RACK KIT1 & KIT2
WF-U24 series receiver units can be mounted in 19” standard rack units using option-
al kits (contact your dealer or go to www.soundsationmusic.com for more details) to
adapt the receiver to any 19” rack. 2 different kits are available:
fWF-RACK KIT1: To set one SOUNDSATION WIREFREE series receiver in one 19” rack
unit.
fWF-RACK KIT2: To set two SOUNDSATION WIREFREE series receivers in two 19” rack
units.
NOTE: WF-RACK KIT2 is designed for use with different SOUNDSATION
wireless systems models. Normally, in the case of receivers with removable
antennas, this kit allows the installation of two receivers in two 19” rack units
(refer to previous image). In the specic case of WF-U24, however, since the
antennas are not removable, the two receivers can t only one 19” rack unit
with antennas folded in order to avoid them to touch each other and be as
much distant as possible.
10.1. WF-RACK KIT1
The kit includes:
A. 2x ¼ rack unit adapter
B. 2x Extension cables for Antenna

wf-u24 User manual
C. 4x Screws to fasten the receiver to the two rack adapters
NOTE: The kit doesn’t include screws to fasten the whole block (receiver and
adapters) to the 19” rack chassis.
WF-RACK KIT1 assembling
1. Remove the two plastic parts on two sides of the receiver.
2. Place the A adapter so that the two lateral holes match those on the receiver side.
3. Fasten the adapter using two screws as shown in the following picture.
4. Repeat steps 1 to 3 of this section on the other side of the receiver.
5. This hole is normally used to attach the extension cables supplied with the kit in
order to place the antennas of the receiver outside the rack. In the specic case of
WF-U24, however, these extensions and this hole are not used because the rear
antennas are not removable.
