DD4MX890J3Wireless Desktop Base Microphone

Wireless Desktop Base The Shure MX890 desktop base for MX405 and MX410 gooseneck microphones offers cable-free installation for corporate boardrooms or other applications requiring flexible microphone configurations. The MX890 operates within the 518–865 MHz bands and is compatible with Shure SLX wireless systems. ©2007, Shure Incorporated 27EN3253 (Rev. 1) Model MX890 Printed in U.S.A. DRAFT 2 Features Sleek, low profile design Frequency agile, microprocessor controlled transmitter IR link to SLX receiver for automatic frequency synchronization Programmable frequency Group/Channel display Programmable mute function Operates on two AA batteries Compatible with all Shure SLX Wireless systems Supports Shure MX405 and MX410 Mini Gooseneck Microphones Commshield™ technology for protection from RF interference • • • • • • • • • DRAFT 3 Microphone Placement Place the MX890 no more than 25 cm (1 ft.) from the edge of the table. Aim the microphone toward the talker and away from loudspeakers and noise sources. Use one microphone for each talker. Pickup angle with a cardioid cartridge is 130° at –3 dB. Pickup angle with a supercardioid cartridge is 115° at –3 dB. Note: To minimize RF interference, maintain a distance of at least 0.3 m (1 ft.) between transmitters. In case of interference, increase the distance between transmitters or change channels. Receiver Make sure the receiver is within sight of the transmitter. Do not place receiver behind a metal barrier or any reflective surface. Refer to the SLX Wireless System User Guide for more information, or visit www.shure.com. 130º 30m (100ft) DRAFT 4 The low-cut filter attenuates frequencies below 150 Hz by 6 dB per octave. Low-Cut Filter Filter disabled (as supplied) Low-cut filter Connecting Gooseneck Align the pin on the microphone flange with the slot on the desktop base. Insert the gooseneck into the desktop base and lock it in place by rotating the gooseneck sleeve clockwise. 1. 2. DRAFT 5 Battery Installation Open the battery compartment as shown. Insert two1.5V “AA” batteries. Make sure the +/– terminals are properly oriented. Note: Alkaline batteries last up to 8 hours. Rechargeable, carbon- zinc and zinc-chloride batteries provide less operating time. 1. 2. Power Meter The battery meter on the LCD shows remaining battery life. Low Power Indicator Steady Red: Power low. Replace batteries immediately Pulsing Red: Batteries dead. Transmitter cannot be turned on until batteries are replaced. DRAFT 6 Press and hold the ON/OFF PROGRAM button for approximately 2 seconds. The LCD illuminates. To turn the transmitter off, press and hold the ON/OFF PROGRAM button again. Note: Use the button on the bottom of the transmitter to power it on without opening the battery compartment. 1. 2. Power On/Off DRAFT 7 Mute Button The mute button can be configured for toggle or momentary operation. Toggle (as supplied) The PUSH button toggles the microphone between active and muted states. NOTE: The microphone always powers up in the active state. Momentary There are two types of momentary operation: Push-to-Mute: The microphone is muted only while the button is pressed and held. Push-to-Talk: The microphone is active only while the button is pressed and held. To change between toggle and momentary: Hold the PUSH button and press the SELECT button. (Test the microphone to confirm the change.) To change between push-to-talk and push-to-mute: Set the button for momentary operation. Hold the SELECT button and press the PUSH button. 1. 2. Hold Hold DRAFT 8 Mute Indicator The desktop base illuminates the gooseneck microphone LED to indicate whether the microphone is active or muted. Refer to the following table: Microphone Status MX405 / MX410 Indicator MX405R / MX410R Light Ring ActiveGreenRed MutedRed/Flashing Green*Off/Flashing* + *To toggle between off and flashing, press PUSH and ON/OFF PROGRAM simultaneously. DRAFT 9 Microphone Status MX405 / MX410 Indicator MX405R / MX410R Light Ring ActiveGreenRed MutedRed/Flashing Green*Off/Flashing* Locking Settings Press ON/OFF PROGRAM and SELECT simultaneously to lock or unlock transmitter settings. When locked, the current settings cannot be manually changed. Note: Locking the transmitter settings does not disable IR frequency synchronization or the High Pass/Low Cut filter. To use with a logic enabled receiver, you must perform an automatic sync. The LCD flashes “log” during sync. Once in logic mode, the LCD flashes “log” when powered up. LOGIC MODE DRAFT 10 Power off all transmitters. Power on all receivers. Begin with the first transmitter. Open the battery cover and power it on. Aim the IR sensor at the first receiver IR port. The transmitter should be no more than 15 cm (6 in.) from the receiver. Press and hold the receiver SYNC button to send group and channel data to the transmitter. The red LED on the transmitter will stop flashing when programming is complete. Power off the first transmitter and repeat the synchronization with each additional transmitter and receiver pair. 1. 2. 3. 4. 5. Press and hold the transmitter SELECT button until the desired group number appears. Press SELECT again and release it when the desired channel number appears. 1. 2. Automatic Frequency Synchronization Manual Frequency Synchronization DRAFT 11 Troubleshooting If you encounter difficulty with the SLX Wireless System: Make sure both the transmitter and the receiver are turned on. Replace the battery if the battery LED is red. Make sure the Group/Channel settings for each transmitter- receiver pair are identical. Make sure there is an unobstructed line of sight between the transmitter and receiver. If necessary, reposition the receiver or decrease the distance between transmitter and receiver. Remove local sources of RF interference, such as computers or lighting equipment. Remove metal objects within 0.3 m (1 ft.) of the transmitter Note: Refer to the SLX Wireless System User Guide for complete troubleshooting procedures. • • • •…
