2 Description
2.1 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. Have fun and impress your audience!

2.2 Packing List

1 SR 40 FLEXX receiver
1 AC adapter (see sticker on packaging)
1 Manual Supplement sheet
Check that the packaging contains all of the items listed for your system. Should any item be missing, please contact your AKG dealer. 2.3 Optional Accessories 2.4 SR 40 FLEXX Receiver For optional accessories, refer to the current AKG catalog or folder, or visit www.akg.com. Your dealer will be glad to help. The SR 40 FLEXX is a stationary diversity receiver for use with all WMS 40 FLEXX and Microtools Series transmitters. It features a half-rack case for mounting in a 19" rack. Operating in the 660 MHz to 865 MHz UHF range, the SR 40 FLEXX provides three selectable, quartz stabilized carrier frequencies within the 3-MHz-wide frequency band for which you ordered your WMS 40 FLEXX. This allows you to select a different frequency if one of the three frequencies does not provide adequate signal quality. The frequencies have been factory preset to make sure you can set up a multichannel system* with up to three channels with three kits operating in the same frequency band. Using a suitable combination of kits operating in different frequency bands you can even use up to nine channels simultaneously. The SR 40 FLEXX is a diversity receiver and uses two antennas in order to receive the transmitter signal at two different spots. The diversity electronics will automatically activate the antenna that delivers the better signal. An adjustable squelch will mute the receiver if the received signal is too weak so the related noise or the self-noise of the receiver will not become audible when the transmitter is switched OFF.
*Ask your dealer about usable frequency bands for WMS 40 FLEXX systems with more than three channels.
2.4.1 Front Panel Controls
Fig. 1: Front panel controls on SR 40 FLEXX receiver. Refer to fig. 1.

1 Antennas: Fixed-length UHF antennas permanently mounted on the front panel. The diversity circuit will automatically activate the antenna that provides the better signal. 2 ON/OFF: On/off pushbutton switch. If the DIVERSITY LEDs A and B flash alternately and the RF MUTE LED is lit constantly, the receiver is ON but receives no signal. If the RF OK, AF OK, and only one of the two DIVERSITY LEDs are lit, the receiver is ON and receives signal. When you switch the receiver OFF, all LEDs will extinguish. 3 RF LEDS: These LEDs indicate the quality of the received RF signal. SR 40 FLEXX

Seite 15

3a OK (green): This LED is lit to indicate that an RF signal of adequate strength is being received. 3b MUTE (red): This LED is lit to indicate that no signal is being received or the squelch is active. In either case, the audio output will be muted automatically. 4 DIVERSITY LEDs A and B: Indicate which of the two receiving antennas is active at any time. 5 Color code: The color indicates the carrier frequency band of the receiver. Transmitters and receivers tuned to the same frequency band are marked with the same color. Refer to the Manual Supplement sheet for a color code table. 6 AF LEDs: Indicate the received audio level: 6a OK (green): -30 dB to +3 dB 6b CLIP (red): >3 dB. This LED illuminates to indicate the audio level of the received signal is overloading the receiver's audio section. The green AF OK LED being lit and the red AF CLIP LED flashing occasionally indicate optimum modulation. If none of the LEDs is lit, the gain setting on the transmitter is too low. 7 VOLUME: This rotary control adjusts the receivers output level from microphone to line level for matching to the input sensitivity of your mixer or amplifier. The control range is 26 dB. 8 Frequency selector: This slide switch tunes the receiver to one of three different carrier frequencies within the receiver's carrier frequency band.
Refer to fig. 1 on page 14.

2.4.2 Rear Panel

Fig. 2: Rear panel of SR 40 FLEXX receiver. Refer to fig. 2.
9 Carrier frequency label: A label indicating the name of the carrier frequency band and the three carrier frequencies of your receiver is affixed to the rear panel of the receiver. 10 AUDIO OUT/BALANCED: Balanced 3-pin XLR audio output for connecting to, e.g., a microphone input on the mixing console. 11 AUDIO OUT/UNBALANCED: Unbalanced audio output on a 1/4" TS jack for connecting to, e.g., a guitar amplifier. 12 Strain relief for the feeder cable of the supplied AC adapter. 13 DC ONLY: Input connector for the supplied AC adapter. 14 SQUELCH: The squelch circuit switches the receiver off if the received signal is too weak, in order to suppress the related noise or the residual noise of the receiver while the transmitter is off. Set the SQUELCH control to minimum before first switching the receiver on.

3 Setting up

Important!

Before setting up your WMS 40 FLEXX, make sure to set the frequency selectors on the transmitter and receiver to the same frequency (1, 2, or 3). If the transmitter and receiver are tuned to different frequencies, no signal will be transmitted! Never use the two audio outputs (BALANCED and UNBALANCED) simultaneously! This may cause signal loss or increased noise. You can either use the receiver freestanding or mount it in a 19" rack using the optional RMU 40 PRO rack mounting kit. For instructions on how to rack mount the receiver, refer to the RMU 40 PRO manual. Reflections off metal parts, walls, ceilings, etc. or the shadow effects of musicians and other people may weaken or cancel the direct transmitter signal. For best results, place the receiver as follows: 1. Place the receiver near the performance area (stage). Make sure, though, that the transmitter will never get any closer to the receiver than 10 ft (3 m). Optimum separation is 16 ft. (5 m). 2. Check that you can see the receiver from where you will be using the transmitter. 3. Place the receiver at least 5 ft. (1.5 m) away from any big metal objects, walls, scaffolding, ceilings, etc.
3.1 Positioning the Receiver
3.2 Connecting the Receiver to a Balanced Input
Fig. 3: Connecting the receiver to a balanced mixer input. Refer to fig. 3.
1. Use a standard XLR cable to connect the BALANCED output (10) on the receiver rear panel to a balanced XLR microphone input on the mixer. 2. Turn the VOLUME control (7) on the receiver front panel all the way CCW to set the receiver output to microphone level.
3.3 Connecting the Receiver to an Unbalanced Input
Fig. 4: Connecting the receiver to an unbalanced mixer input. Refer to fig. 4.
1. Use a standard 1/4" jack cable to connect the UNBALANCED jack (11) on the receiver rear panel to an unbalanced 1/4" line input on the mixer. 2. Turn the VOLUME control (7) on the receiver front panel all the way CW to set the receiver output to line level. To avoid hum interference, do not use audio cables that are longer than 10 feet (3 m)!

3.4 Connecting the Receiver to Power
Fig. 5: Connecting to power. 1. Check that the AC mains voltage stated on the included power supply is identical to the AC mains voltage available where you will use your system. Using the power supply with a different AC voltage may cause damage to the unit. 2. Point the antennas (1) upward. 3. Plug the feeder cable on the included power supply into the DC ONLY socket (13) on the receiver. 4. Bend part of the feeder cable into a small bight, pass the bight through the strain relief (12) from above, and slip the bight over the hook on the strain relief (12). Tighten the cable. 5. Plug the AC adapter into a convenient power outlet. 6. To switch power to the receiver on, press ON/OFF (2). To switch power to the receiver off, press ON/OFF (2) again. Your receiver can only receive the transmitter signal if a) the transmitter and receiver operate within the same frequency band; and b) the transmitter and receiver are set to the same frequency within this frequency band.

Refer to fig. 5.

3.5 Setting Frequencies

Seite 18

1. Check that the carrier frequency (frequencies) of the transmitter is (are) identical to the receiving frequencies of your SR 40 FLEXX. The carrier frequency (frequencies) of the transmitter and the receiving frequencies of the receiver are indicated in MHz on the respective frequency stickers and in the respective Manual Supplements. 2. HT 40 FLEXX and PT 40 FLEXX: Set the frequency selector on the transmitter and the frequency selector (8) on the receiver to the same positions (1 - 1, 2 - 2, or 3 - 3). HT 40 PRO, PT 40 PRO, Microtools: Switch power to the transmitter and receiver ON. If the RF MUTE LED (3b) on the receiver is lit, set the frequency selector (8) on the receiver to a position where RF MUTE (3b) goes out and the RF OK LED (3a) comes on. 1. Move the transmitter around the area where you will use the system to check the area for "dead spots", i.e., places where the field strength seems to drop and reception deteriorates. If you find any dead spots, try to eliminate them by repositioning the receiver. If this does not help, avoid the dead spots. 2. The RF OK LED (3a) on the receiver going out means no signal is being received or the squelch is active. Switch the transmitter on, move closer to the receiver, or set the squelch threshold to the point that the green RF OK LED (3a) will be lit. 3. If the received signal is noisy, set the squelch threshold to a level where the noise will stop.
Never set the squelch threshold any higher than absolutely necessary. The higher the squelch threshold (-70 dBm = max., -100 dBm = min.), the lower the sensitivity of the receiver and thus the usable range between transmitter and receiver. The spacing between the three frequencies of each WMS 40 FLEXX transmitter and receiver is wide enough for operating three radio channels simultaneously within the same frequency band with no mutual interference. For systems with up to nine channels you will need WMS 40 FLEXX kits in up to three different frequency bands. Please ask your dealer which frequency bands are suited for multichannel use and approved for the place where you will use the system. Perform steps 1 through 6 for each frequency band separately. 1. 2. 3. 4. 5. 6. Switch power to all transmitters and receivers off. Set the frequency selectors on the transmitter and receiver for channel 1 to "1". Set the frequency selectors on the transmitter and receiver for channel 2 to "2". Set the frequency selectors on the transmitter and receiver for channel 3 to "3". Set up the transmitter and receiver for channel 1. Repeat steps 1 through 5 for channels 2 and 3.

Do not operate two or more wireless channels on the same frequency at the same time and location. This would cause unwanted noise due to radio interference. Prior to changing a carrier frequency, be sure to switch the transmitter off. To activate the new carrier frequency, switch the transmitter back on.
