Description 2 Description Introduction Thank you for purchasing an AKG product. This Manual contains important instructions for setting up and operating your equipment. Please take a few minutes to read the instructions below carefully before operating the equipment. Please keep the Manual for future reference.
Description Front panel Figure 1: Controls on the front panels of the DSR 70 Dual and Quattro receivers The controls (2 and 3) and the LEDs (4 to 6) are the same for all channels. NOTE 1 On/off button: This button is lit green when the receiver is switched on and ready for use. It is sufficient to switch off the receiver to switch off the DMS 70 system. Switching off the receiver switches off all transmitters connected to this receiver.
Description Rear panel Figure 2: Controls on the rear panels of the DSR 70 Dual and Quattro receivers 8 AUTO CORRECTION switch: to adjust internal error correction. 9 Sum output/BALANCED (x1): Balanced audio output to 3-pin XLR connector. This output transmits the combined audio signal of all 4 channels and you can connect it directly to an active speaker. 10a CHANNEL OUT (x2): Balanced audio output to 6.35 mm jack. This output transmits the audio signal of the respective channel.
Description DHT 70 handheld transmitter The DHT 70 handheld transmitter operates within the 2.4 GHz ISM frequency range. The transmitter uses two antennas integrated within the housing. The capsule in the transmitter is the patented dynamic AKG D5 capsule with its hypercardioid directional characteristic. It provides low handling noise sensitivity, high gain before feedback and brilliant sound quality, as well as a built-in wind and pop filter to reduce wind and breath noise.
Description DHT 70 Perception handheld transmitter The DHT 70 Perception handheld transmitter has a dynamic standard capsule with a cardioid directional characteristic. The controls are identical to those on the DHT 70. Description of the controls (Page 27).
Description DPT 70 bodypack transmitter You can use the DPT 70 bodypack transmitter with both dynamic microphones and condenser microphones operating on a supply voltage of approx. 4 V. Naturally you may also connect an electric guitar, electric bass or keytar. The DPT 70 operates within the 2.4 GHz ISM frequency range. Controls 13 Status LED: Indicates the transmitter's operating status.
Description Microphones, guitar cables The following AKG microphones can easily be connected to the audio input of the DPT 70: • C 520 L, C 555 L, C 544, HC 577, CK 77 WR-L, CK97 • C 516 ML, C 518 ML, C 519 ML, C 411 L • The MKG L guitar cable from AKG lets you connect an electric guitar, electric bass or keytar to the bodypack transmitter. The MKG L guitar cable is included in the Instrumental Set and the Mixed Set and is also available separately as an accessory.
Installation and Connection 3 Installation and Connection Positioning the receiver 1) 2) Rack assembly Assembling the DSR 70 Dual in a 19" rack Always position the receiver near to where the action is taking place (e.g. stage). Check that you can see the receiver from where you will be using the transmitter. Figure 6: Assembling the DSR 70 Dual in a 19" rack For assembling one or more DSR 70 Dual receivers, the RMU 40 PRO rack assembly set is available in the current AKG catalogue/folder or at www.
Installation and Connection Connecting the audio outputs of the DSR 70 Connecting the receiver to a balanced input Quattro receiver Use an XLR cable to connect the BALANCED output (10) of the required channel on the back of the receiver to the balanced microphone input (XLR socket) on the mixer or amplifier. Connecting the receiver to a speaker Use an XLR cable to connect the sum output (9) of all four channels on the back of the receiver to an active speaker.

Switch on the receiver. Press Connect (3) on a free channel of the receiver and hold down until the status LED (5) starts to flash after approximately 2 seconds. You need to confirm with the transmitter within the next 30 seconds.
Setting up Connecting an instrument 1) Remove the battery compartment cover (22). 2) Plug the jack plug on the MKG L guitar cable into the output jack of your instrument and the mini XLR connector on the guitar cable into the audio input socket (19) of the bodypack transmitter. 3) Slide the slide cover (20) to the rear position and switch on the bodypack transmitter using the on/off switch (15). 4) Assign a free channel to the bodypack transmitter and receiver. 5) Play your instrument.
Microphone technique 5 Microphone technique DHT 70 handheld transmitter A handheld vocal microphone provides many ways of shaping the sound of your voice as it is heard over the sound system. The following sections contain useful hints on how to use your DHT 70 handheld transmitter for best results. Working distance and proximity effect Basically, your voice will sound bigger and mellower, the closer you hold the microphone to your lips.
Microphone technique DPT 70 bodypack transmitter CK97 lavalier microphone Fix the microphone to the supplied lavalier clip or to the optional H 41/1 tiepin. 1) Clip the microphone onto the speaker's clothing, as close as possible to his or her mouth. The closer the microphone is to the speaker's mouth, the less danger there is of feedback. NOTE 2) Make sure to aim the microphone towards the user's mouth. C 544 L headset microphone Putting on the microphone 1) Put the microphone on.
Cleaning 6 Cleaning Unplug the power supply unit from the socket. Clean the surface of the unit with a moistened (not wet) cloth. Never use caustic or scouring cleaners or cleaning agents containing alcohol or solvents, since these may damage the enamel and plastic parts. ATTENTION Internal windshield of handheld transmitter 1) 2) 3) 4) DMS 70 Quattro/Dual Unscrew and remove the wire-mesh cap of the handheld transmitter.
