The XP40iw Wireless Microphone
Using the Xp49i Wireless Microphone
1. Audio on-off switch – When set to the “ON” position, audio signal is transmitted. When set to the
“OFF” position, the audio signal is muted. Because the carrier signal remains during muting. No “pop”
or “thud” will be heard. Note that turning this off does not turn off the transmitter power – it is simply a
way to temporarily mute the transmission of audio signal. If you don’t plan on using the HT5 for
extended periods, turn off its power by using the power on-off switch. (see #3 below)
2. Battery level meter - This set of three multicolor LEDs indicates relative battery power, indicating
whether the installed battery is at low (red), mid (yellow) or high (green) strength. One or more of these
will light whenever the HT5 is powered on (see #3 below). When all three are lit, the battery is at
maximum strength. When only the red “low” indicator lights, RF performance is degraded and the
battery needs to be replaced.
3. Power on-off switch* -Use this to turn the HT5 on or off (to conserve battery power, be sure to leave
it off when not in use).
4. Gain control (trimpot) – This input sensitivity control has been factory preset to provide optimum
level for the particular microphone capsule provided with the system and so it is not to be adjusted.
5. Battery holder – Insert a standard 9-volt alkaline battery here, being sure to observe the plus and
minus polarity marking shown. WARNING: do not insert the battery backwards; doing so can cause
severe damage to the HT5.
* Be sure to turn down the WIRELESS LEVEL control before turning transmitter power on or off, or an
audible pop may result.
The basic procedure for setting up and using the wireless system takes only a few minutes;
1.
For the system to work correctly, both the receiver and transmitter must be set to the same channel.
2.
Physically place the unit where it will be used (the general rule of thumb is to maintain “line of sight”
between the receiver and transmitter so that the person using the microphone can see the unit.
3.
Make sure the Power on-off switch in your HT5 handheld transmitter is set to “Off”.
4.
On the HT5 handheld transmitter, unscrew the bottom section of the microphone by turning it
counterclockwise and then slide it off.
5.
Place a fresh 9-volt alkaline battery in the transmitter battery holder, taking care to observe the
polarity markings
6.
Turn the WIRELESS LEVEL knob on the XP40iw completely counter clockwise. Connect the
supplied AC adapter into any standard AC outlet. Press the rear panel POWER switch to turn on the
SP40iw.
7.
Turn on the power to the HT5 transmitter (using its Power on-off switch); all three Battery strength
LEDs will light if the battery is sufficiently strong. At this point, the RF LED on the rear panel of the
receiver will light. Replace the bottom section of the HT5 handheld microphone by sliding it on and
then screwing it back on. Leave the transmitter off for the moment.
8.
Now it’s time to set the audio level. Make sure that your HT5 transmitter is unmated by setting its
AUDIO switch to “On”. Speak or sing into the mic at a normal performance level and raise the
WIRELESS LEVEL control until the desired level is reached.
Bear in mind also that the HT5 microphone is unidirectional which means it picks up sound from
the front of the mic and rejects sound from the rear. This will help reduce the chance of feedback. In
general, you can avoid feedback by taking care not to use any microphone directly in front of a PA
speaker (if this is unavoidable, try using the equalizer to attenuate those high- or mid-range
frequencies which are causing the feedback “squealing”).
9.
If you hear distortion at the desired volume level, check the rear panel PEAK LEAD. If it is lit red,
turn down the WIRELESS LEVEL until it lights only occasionally. If you still hear distortion, do the
following:
•
The HT5 transmitter’s Gain control has been factory preset to provide optimum level of the
particular microphone being used so no adjustment is necessary. Any distortion present should
therefore simply be a matter of the microphone being too close to the mouth; try moving it further
away.
Note that following this setup procedure, you can always lower the Volume knob of the XP40iw in
order to further attenuate the output signal if necessary.
10. When first setting up the XP40iw in a new environment, it’s always a good idea to do a walk-around
in order to make sure the coverage is provided for your entire performance area. As you do s, the
“RF” LED on the rear panel of the XP40iw should always remain lit. Always try to minimize the
distance between transmitter and receiver as much as possible so that the strongest possible signal
is received from all planned transmission points.
