User manual AKG PT 300

[. . . ] The controls are easy to locate and recessed in the case in order to prevent accidental actuation. The PT 300 operates within a cannel bandwidth of up to 20 MHz in the high-band UHF range from 770 MHz to 950 MHz and lets you select one of 16 carrier frequencies within the channel bandwidth. The audio input on a lockable mini jack accepts dynamic microphones as well as condenser microphones for 5-V power supply. 2: 15 - Antenna 16 - MIC/MUTE/LINE switch for microphone power supply and mute function 17 - POWER 0/I power on/off switch 18 - Power LED 11 Optional Accessories RA 300 B: Antenna with integrated booster PS 300: UHF antenna splitter with 2 x 8 antenna outputs for SR 300 receivers MK PS: Antenna splitter connecting cable MK A10: 10-m (33-ft. [. . . ] We need this information to ensure your new equipment will be compatible with the original units. (Tabelle:) Schalter = Switch Kanal = Channel Important: Be sure to switch the transmitter off prior to selecting a different carrier frequency and back on afterwards. Important: Be sure to switch the transmitter off prior to selecting a different carrier frequency and back on afterwards. Unlock the battery compartment door (26) by turning the locking screw CCW through 90 degrees using a coin. If you insert the battery with reversed polarity the bodypack transmitter will not function. Close the battery compartment door (26) and slide it back inward against the direction of the arrow until it clicks shut. Set the POWER 0/I switch (7) to I to switch the power on and observe the red (3) and green (4) status LEDs to check that the transmitter operates correctly (see table below). Note that POWER 0/I (7) switches the power to the entire transmitter on and off and MIC 0/I (6) only switches the microphone capsule in and out. Remove the first two batteries and pull the battery ejector (12) toward the antenna. Push the battery ejector (12) back in and insert the new batteries referring to step 2 above. Lock the battery compartment door (26) by turning the locking screw CW through 90 degrees. Set the POWER 0/I switch (17) to I to switch the power on and observe the red (20) and green (18) status LEDs to check that the transmitter operates correctly (see table below). Note that POWER 0/I (17) switches the power to the entire transmitter on and off. SR 300 True Diversity Receiver The SR 300 receiver has been supplied to you with a remote power supply which is factory set for the AC voltage used in your country (110 V or 220 V). WARNING: Do not operate the remote power supply on any AC voltage other than the one stated on the type plate. Connect either the balanced XLR audio output (37) or the unbalanced audio output (38) (1/4" jack) to the desired input on the mixing console, amplifier, or other equipment. Check that the supplied remote power supply is the correct model for your local AC power voltage. Connect the power supply to the power input socket (39) on the receiver and insert the cable into the strain relief as shown in fig. With the transmitter switched OFF (if it were switched on it would suppress low-level unwanted sig14 Nals), check whether there is any audible RF noise at the receiver audio output. If there is, turn the SQUELCH control (28) CW to the point that the MUTE LED (29) illuminates red and the RF noise stops. The DIVERSITY LEDs A and B (32) illuminate to indicate which of the two antenna inputs is routed to the audio output at any time. At this setting the transmitter is driven to rated deviation and you still have 6 dB of headroom.
