Frequently Asked Questions - 1201XT Azden

How do I set the frequency on my Azden 1201XT transmitter?

Press the MODE button with a paperclip tip to switch between frequency and channel display. Use the UP/DOWN buttons to select the desired frequency or channel. Ensure the receiver is set to the same frequency. There are 188 selectable frequencies.

What type of batteries does the 1201XT use and how long do they last?

The 1201XT uses two AA alkaline batteries. Battery life is approximately 8 hours with typical use, depending on whether phantom power is enabled. A low battery indicator blinks when voltage falls below 2.2V.

Can I use any dynamic or condenser microphone with the 1201XT?

Yes, the 1201XT accepts any low-impedance dynamic microphone via its 3-pin XLR connector. For condenser microphones requiring phantom power, enable the 48V phantom power switch. The XLR pinout is: pin 1 ground, pin 2 audio+/48V, pin 3 audio-.

How do I adjust the input gain on the 1201XT?

Use a small screwdriver to turn the input level adjustment trimmer (marked with a '*' or 'D'). Clockwise increases gain, counterclockwise decreases gain. Aim for 4-5 audio level segments on the display without constant full illumination.

What is the effective operating range of the 1201XT?

The typical operating range is 200 to 300 feet (60 to 100 meters) in open line-of-sight conditions. Range may vary due to obstacles, RF interference, and antenna placement.

How can I check the remaining battery life on the 1201XT?

The LCD displays up to 3 battery segments on the left side. Three segments indicate full charge. The bottom segment blinks when battery voltage drops below 2.2V DC, signaling it's time to replace batteries.

What does the 'STBY' switch do on the 1201XT?

The STBY (standby) switch mutes the audio output while keeping the RF carrier active. This prevents noise when you are not speaking, and you can quickly switch back to ON to resume transmission.

Can I use rechargeable batteries in the 1201XT?

Azden recommends using alkaline batteries only. Rechargeable batteries (NiMH) may have lower voltage and shorter life. If you must use them, ensure they are fully charged and replace them more frequently.

How do I clean and maintain the 1201XT transmitter?

Wipe the exterior with a soft, dry cloth. Do not use solvents or abrasive cleaners. Keep the XLR connector dry and free of debris. Store in a cool, dry place. Remove batteries if not used for extended periods to prevent leakage.

Is the 1201XT compatible with Azden 1201URX receivers?

Yes, the 1201XT is designed for use with the 1201URX series receivers, including 1201URX/AB, 1201URX/VM, and 1201URX/Si. Set both transmitter and receiver to the same frequency/channel for proper operation.

QUALITY YOU CAN HEAR

E. Display

In addition to showing the frequency and the channel number, the display [①] also shows other useful information.

The LCD segments on the left show the approximate remaining battery life (from 1 to 3 segments) with 3 segments meaning maximum battery power. The bottom segment will blink when the battery power falls to less than 2.2VDC and indicates that it is time to replace the batteries. Azden recommends the use of Alkaline batteries only.

Across the top of the display up to 5 segments will illuminate depending on the strength of the transmitted audio signal - From 2 (weak) to 5 (strong). The first (left) segment will light when the AUDIO switch is turned ON. The best audio is achieved when 4 to 5 segments are lit. If all 5 segments are lit continually, the signal is too strong and could overload the input of the receiver. Move the microphone further away from the sound source.

The display can also show the total number of hours of use (change to this display using the mode [5] button. To start, after choosing the TIME mode, press the UP [6] Button until the display shows 00:00. Then, each time the transmitter is turned ON the clock will keep track of the total hours and minutes used. This is a handy way of keeping track of battery life.

USING THE 1201XT TRANSMITTER'S CONTROLS AND DISPLAY

A. Power

The POWER ON/OFF switch [ ] Turns the 1201XT ON or OFF.

B. Audio

Prior to turning the 1201XT ON it is best to set the AUDIO switch [ ] OFF. When ready to begin transmitting, switch to ON. The OFF position acts as a "mute" maintaining the RF signal but turning off the audio.

C. MIC Connector/Locking Ring

This 3-pin XLR connector [ ] is the microphone input. Any low impedance microphone with a corresponding connector can be attached here. If the microphone requires external power (Phantom Power) the 1201XT can supply 48VDC. The XLR connector is wired with pin #1 as ground, pin #2 as audio + (and +48VDC when Phantom Power is ON) and pin #3 as audio -.

Once the microphone is plugged into the 1201XT the locking ring [ ]④ should be rotated clockwise until snug. To remove the microphone, first rotate the locking ring counterclockwise and then, while pressing the XLR release, pull the microphone straight away from the 1201XT.

D. Input Level Adjustment

This screwdriver adjustment [ ] controls the input level of the microphone. Counterclockwise rotation reduces the input gain while clockwise rotation increases the input gain.

RECEIVER SETUP/USE - 1201URX/AB or 1201URX/VM

As the RF signal from the transmitter gets stronger (or weaker) the number of illuminated LCD segments in the display will change - with 3 segments being the maximum and best. Similarly, the AF (audio level) segments will light from 1 to 3 segments as the audio gets stronger or weaker. In this case, the best level is achieved as the display shows between 2 and 3 segments. If all 3 segments stay illuminated for a continued period of time it is likely that you are over-driving the receiver's input and you should reduce the transmitting level by either moving the microphone further away from the sound source or reducing the input gain on the transmitter.

THE 1201URX/Si

The 1201URX/Si receiver is specially designed to work with specific Panasonic "Slot-In" or Ikegami "Uni-Slot" cameras. Once mounted in the camera, the DB-25 connector on the bottom provides the receiver with power directly from the camera's power supply (battery) while delivering audio directly to the camera's audio input. Items A. [⑪], C., D. [⑦] and G. [⑥] on pages 1 and 2 apply directly to the 1201URX/Si

1201URX/Si Top panel display and operation:

The MODE Switch [⑨] performs 1 of 5 functions.

Initial MODE display:

The initial MODE shows the receiving band shown as Group, Channel and Frequency. If there is no action taken with the MODE switch for 4 seconds the display will return to the Initial Display. Pressing the MODE switch for one second while showing the Initial Display will cause the currently set frequency to be displayed.

Mode #1 (GR):

From the Initial Display, quickly pressing the MODE switch once displays the Group Display. Pressing the UP or DOWN buttons will change the Group Number. There are 7 Groups, 6 of which have the best selection of frequency combinations when using multiple systems. Group 0 allows for choosing any channel/frequency. The last Group is memorized when the receiver is turned OFF. The chart on page 3 shows the Group vs Frequency combinations.

Mode #2 (CH):

To change the channel/frequency within the selected group, press the MODE switch a 2nd time. "CH" will be displayed. Using either the UP or DOWN button[] the desired receiving channel/frequency combination can be set (the chart on page 3 shows the relationship). Tapping the button steps the channel/frequency number one at a time while pressing and holding the button moves through the combinations rapidly. There are 188 different channel/frequency combinations to choose from "Group" allows you to select all of the combinations). Once the desired channel/frequency has been determined set both the transmitter and receiver to match. When the receiver is turned OFF the last channel/frequency chosen is stored in memory.

Mode #3 (SQ):

To change the squelch level, press the MODE switch for a third time. "SQ" will show in the display. There are 3 settings to choose from:

$$ \begin{array}{l} \text { on on } = \text { RF mute ON - Tone mute ON (default) } \ \text { on off } = \text { RF mute ON - Tone mute OFF } \ \text { off off } = \text { RF mute OFF - Tone mute OFF } \ \end{array} $$

You can cycle through these with the UP/DOWN buttons. The squelch returns to the default when the receiver is turned OFF.

Mode #4 (SQ Level):

There are four levels of Squelch to choose from:

0 = Default

3 = 3dB (RF) increase to the default
-6 = 6dB (RF) decrease to the default
-3 = 3dB (RF) decrease to the default

You can cycle through these with the UP/DOWN buttons.

See the discussion at the bottom of page 2 and the top of page 4 for information concerning the other parts of the display.
