THE 1200BT TRANSMITTERPowering the 1200BT TransmitterThe 1200BT uses two “AA” batteries for power. The batteries areplaced in the battery compartment by sliding the battery compart-ment door [k] down and placing the batteries in the compartment asshown in the illustration [♠]. When installing the batteries, be sure tofollow the correct polarity. DO NOT FORCE THE BATTERIES INTOTHE COMPARTMENT. Azden does not recommend the use of re-chargeable batteries.Setting the Transmitting Frequency on the 1200BTBefore the 1200BT can be used, it and the associated receiver haveto set to the same frequency. This can be accomplished on the 1200BTtransmitter by first setting the LCD display to one of two views - ‘Fre-quency’ or ‘Channel’. To do this, after installing fresh batteries, turnthe 1200BT to the ON position [e]. Next, using the tip of a ballpointpen, an unbent paper clip or something similar, press the MODEbutton [j] repeatedly until one of the two following screens appears.G. Display (continued)life (from 1 to 3 segments) with 3 segments meaning maximum bat-tery power. The bottom segment will blink when the battery powerfalls to less than 2.2V and indicates that it is time to replace the bat-teries. Azden recommends the use of Alkaline batteries only.Across the top of the display, up to 5 segments will illuminate de-pending on the strength of the transmitted audio signal - from 2 (weak)to 5 (strong). The first (left) segment will light when the ST.BY switchis turned to ON. The best audio is achieved when 4 to 5 segmentsare lit. If all 5 segments are lit continually, the signal is too strong andcould overload the input of the receiver. Either move the microphonefurther away from the sound source or reduce the microphone inputgain [♣].The display can also show the total number of hours of use (changeto this display using the MODE [j] button). To start, after choosingthe TIME mode, press the UP [l] button until the display shows00:00. Then, each time the transmitter is turned ON the clock willkeep track of the total hours and minutes used. This is a handy wayof keeping track of battery life.1234 5 678910♣♠14
Using either the UP or DOWN button [l] the desired receiving fre-quency or channel number can be set. Tapping the button steps thefrequency or channel number one at a time while pressing and hold-ing the button moves through the frequencies or channel numbersrapidly. There are 188 different frequencies or channel numbers tochose from. Once the desired frequency or channel has been deter-mined be certain to set both the transmitter and receiver to match.Using the 1200BT Transmitter’s Controls and DisplayA. PowerThe POWER ON/OFF switch [e] turns the 1200BT On or OFF.B. AudioPrior to first turning the 1200BT ON it is best to set the AUDIO switch[g] to ST.BY (standby). When you are ready to begin transmitting,switch to ON. The ST.BY position acts as a ‘mute’ that maintains theRF signal but turns off the audio.C. MICThis 4-pin Hirose connector [h] is the microphone input. Azden pro-duces a number of lapel, head-worn and neck-worn microphonesthat are specifically suited for the 1200BT. In addition, other exter-nally powered (5VDC) electret condenser microphones can be usedwhen they are properly wired with the correct Herosi connector (pin 1is for audio +, pin 2 is not used, pin 3 is for bias voltage and pin 4 isground). If you are using the 1200BT as a wireless instrument trans-mitter the connections are somewhat different (pin 1 is not used, pin2 is the audio +, pin 3 is for bias voltage and pin 4 is ground).D. Input Level AdjustmentThis screwdriver adjustment [♣] controls the input level of the micro-phone. Counterclockwise rotation reduces the input gain while clock-wise rotation increases the input gain.E. Belt ClipThe metal beltclip [c] provides a convienent method of attachingthe transmiiter to the user.F. AntennaThe antenna [d] should be kept clear of metal objects.G. DisplayIn addition to showing the frequency and channel number, the dis-play [i] also shows other useful information.The LCD segments on the left show the approximate remaining bat-tery2 3
