To release the lock so that you can check for alternative clean channels press and hold both Channel buttons in at the same time. After 3 seconds the Channel display will ash and you can change and check the channels using the up and down buttons. Once you have chosen a suitable channel to use leave it ashing for 15 seconds to lock it in as indicated by a solid chan-nel number. Now set the transmitter channel to match.
3Wireless Microphone System Operating Manual3. RECEIVER INSTALLATIONAudio output connectionThere are two audio outputs on the back of the U-Series SDR5716 Receiver, a Mic-level balanced XLR-M and Line-level unbalanced 6.35mm jack. We have supplied you with a balanced cable that goes from the XLR output into a TRS 6.35mm jack plug as used on the Fitness Audio Aeromix 2+2 and HRX-32 Mixers.This cable is a perfect match for an Aeromic/Cyclemic or E•Mic/V•Mic, the balanced cable connection will deliver the highest sound quality possible from any microphone, with more “body” in the voice being the main audible dierence. This audio connection is shown below.AF OUT 1 2 3 1. GND 2. + 3. - BALANCED ANTENNA-B ANTENNA-A DC-IN 10V-15V SQ However, if your mixer has an XLR input socket, then it’s best to purchase a balanced XLR-F to XLR-M cable to connect the receiver to the Mic Input. Some mixers will also ac-cept an unbalanced jack to jack lead mic connection with the receiver’s output volume control adjusted down to suit as an alternative connection, but a balanced cable con-nection is the better one to use.Rack Mounting the ReceiverThe Fitness Audio SDR5716 Receiver is a 19” half-rack mount design and is supplied with a specially designed 19” rack mount adapter so can be bolted into equipment cabinets. Assemble as shown in Fig 3. We have also supplied you with a pair of antenna extension cables so that the two antennas can be mounted into the holes on the rack ears out front in the air and not trapped inside a steel box.
4Wireless Microphone System Operating ManualA double receiver rack mount kit is available as an optional extra if required (Fig. 4).Positioning the ReceiverFor best operation, the receiver should be at least 1m above the ground and at least 1m away from a wall or metal surface to minimize RF reections. 4. THE BELT-PACK TRANSMITTER (SM716)Channel Selection and GainThe channel selector and gain adjustment are located under the battery cover as shown in the picture below. To make channel selection remove the cover and select a channel by turning the Channel Selector(6) with a small screwdriver. Gain adjustment for Lavalier and Headset microphones can be done by adjusting the MT trimpot(5), whereas GT trimpot(4) is for the gain adjustment of an Electric Guitar or other high impedance line level inputs. If you’re using the Transmitter with an Aeromic then turn down the MT trimpot to minimum. If using an E•Mic or V•Mic then leave the MT trimpot at full and turn down only if distortion is evident.Due to minor variations in the casing sizes of many brands of 9V batteries, the trans-mitter battery compartment is designed to accommodate the preferred 9V size battery made by Eveready - the Energizer 9V Alkaline – but other brands may also work well. Re-chargeable Ni MH batteries @ 170-190mAH ratings may need to be re-charged after about 1.5 – 2.0 hours of continuous use, whereas Alkaline 9V Bat-teries will generally be suitable for about 6 – 8 hours of airtime with the Aeromic or E•Mic/ V•Mic wireless microphones.1.

5Wireless Microphone System Operating ManualA range of transmitter Pouchbelts in dierent styles and colours which can be worn un-der or over your clothes are available for many dierent users, including tness instruc-tors, actors, musicians and professional presenters. For more details please consult your FA System supplier or visit our website: http://www.tnessaudio.com.au/Pouchbelts shown L - R: Standard, Hipster, Zipster, Grey Zipster, Beige Theater belt.5. MINI TRANSMITTER (MT-U8)If your system has been supplied with a Mini Trans-mitter then it will already be wired to an Aeromic or Cyclemic, E•Mic or V•Mic either attached to the frame or with an Arm Pouch or Waist Pouchbelt to suit.To select the matching channel to the Receiver rst remove the battery cover and with the small screwdriver supplied change the channel to match the one shown on the LED screen. Please note that the MT-U8 is an 8 channel transmitter and will normally be supplied lining up with channels 01-08 on the receiver, in some countries a “B” group of channels may also be available (Ch. 09-16). In both cases the channels line up with the same number on the receiver and then repeat so that channel 00 is also channel 08. If you wish to use multiple MT-U8/SM716 systems under the one roof then at least 4 channels are ne to use without interference from each other, in the case of the 630-650MHz range it is channels 1,4, 5 or 8 and of course, if you are also using a beltpack transmitter in the same or another room nearby, then it can be set to a channel in the 09-16 group of which channels 10, 12,14 or 16 will work best with channels 1,4, 5 or 8.
6Wireless Microphone System Operating ManualThere will be dierent, non-conicting channels in other frequency groups supplied around the world so please check with your dealer or national supplier for this informa-tion. Fit an Alkaline AAA battery into the battery compartment, re-t the lid and push the sealed on/o button. A tiny blue LED illuminates to let you know it’s on. When that LED starts ashing then the usable power is running low and it’s time to change the battery. One AAA battery will supply over 5 hours of air time. Re-chargeable AAA bat-teries can also be used.Using Multiple Transmitters At One Location Please note that the MT-U8 is an 8 channel transmitter and will normally be supplied lining up with channels 01-08 on the receiver. In some countries a “B” group of chan-nels may also be available (Ch. 09-16). In both cases the channels line up with the same number on the receiver and then repeat - so that channel 00 is also channel 08 on the MT-U8. If you wish to use multiple MT-U8/SM716 systems under the one roof then at least 4 channels can be used without causing interference with each other. In the case of the 630-650MHz range, channels 1,4, 5 or 8 can be used together. If you are also us-ing a beltpack transmitter in the same or another room nearby, then that should be set to a channel in the 09-16 group, of which channels 10, 12,14 or 16 will work best with channels 1,4, 5 or 8. There will be dierent, non-conicting channels in other frequency groups supplied around the world so please check with your dealer or national supplier for this information.6. REMARKSRF InterferenceIf you encounter receiving interference (from other than an operating TV station), it can often be overcome by adjusting the receiver’s squelch control, as described below. Please note that wireless frequencies are shared with other radio services, and according to FCC regulations wireless microphone operations are unprotected from interference from licensed operations in the band. If any interference is received by any Government or non-Government operation, the wireless microphone must cease operation. (The above statement is valid for the U.S.A.)Receiver Squelch controlThe squelch control on the back panel of the receiver is preset at the factory, but can be adjusted if you must use the system in a high RF interference area. If there is audio output from the receiver when your transmitter is OFF, adjust the squelch control so the system will receive the signal from your transmitter but squelch or eliminate the un-wanted background RF noise. This adjustment can cause a reduction in usable range of the wireless transmitter, so set the control to the lowest position which reliably mutes the unwanted RF signal.
7Wireless Microphone System Operating ManualBatteriesMany batteries are known to leak conductive and/or corrosive liquid when not used for a period of time. Please remove the batteries from the transmitter if it is not to be used for a period of a few days or more.7. THE OPTIONAL HANDMICThe Fitness Audio SDR5716 Receiver is compatible with certain models of Chiayo handheld microphones such as the SQ-1016 pictured below. For more information please consult your Fitness Audio supplier. Please note that you can only use one mic transmitter at a time with the FA Series Receivers so make sure your other transmitter is turned o before using a handmic transmitter.
