Digital IEM System FCC Notice NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. The equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
QUADRA System Overview The Quadra system provides an entirely new level of audio and RF performance in a wireless monitor system. The combination of analog or digital input capability, ultra-low latency 24 bit, 48 kHz audio, digital RF modulation and discrete four channel mixing capability make the Quadra a truly unique IEM product for mission-critical, professional applications. The system is designed for line level analog audio signals and AES/EBU digital audio input signals.
Digital IEM System Receiver Operation Battery Insertion The receiver is powered by three AA batteries, either alkaline, lithium, or rechargeable types. Do not use “heavy duty” batteries from a drug store - they will not last long in the M4 receiver. Open the battery door by pressing on it while sliding it downward. It should then flip open allowing full access to the battery compartment. Carefully note the battery orientation as indicated by the diagrams inside.
QUADRA LCD The boot sequence will briefly display the company logo, model number and firmware revision. Selecting 2-channel or 4-channel Operation The Chan. Setup screen allows you to select whether the receiver operates in 2 ch., 4-ch. or split 4-ch. modes, and then how the knobs on the top of the receiver are configured as a mixer. Following the boot-up sequence, the receiver will revert to the Main Window, showing the following: • Operating frequency at the upper left (Frq1, Frq2, etc.
Digital IEM System 2-channel Operation 2 CHANNEL - Master (1,2) mode (factory default) NOTE: the transmitter must be also in 2 ch. mode for the receiver to operate in this manner. 2-ch. mode allows for three different knob setups: • Master(1,2) This is the factory default and is equivalent to standard IEM systems where only a stereo signal is used. The tall, thin knob is the stereo master volume.
QUADRA 4-channel operation 4 CHANNEL - Master (1,2) + 3,4 mode In this mode, all four audio channels fed to the transmitter are available at the receiver. AUDIO CH. 1 2 AUDIO AUDIO CH. 3 CH. 4 MASTER VOLUME NOTE: the transmitter must be in 4 ch. mode for the receiver to work in this manner.
Digital IEM System Split 4-channel operation Split 4-ch. mode allows you to use a single M4T transmitter to send two different stereo mixes to two different receivers or groups of receivers using a single radio frequency. NOTE: the transmitter must be in 4 ch. mode for the receiver to work in this manner. SPLIT 4 CHANNEL - Master (3,4) mode AUDIO CH. 3 4 NO FUNCTION MASTER VOLUME Split 4-ch.
QUADRA Tune Pan To select your operating frequency, choose Tune in the menu list, and press the MENU/SEL button. Here, you can choose between four operating frequencies in the 4-ch mode or Split 4-ch mode, or eight operating frequencies the in 2-ch mode. To select your overall stereo balance and stereo panning for individual audio channels, use the arrow buttons to highlight Pan in the menu list. Press the MENU/SEL button to enter the setup screen.
Digital IEM System Limiter This feature can be used in order to provide audio limiting at the receiver in order to prevent excessive levels at the headphones or earbuds. To set the amount of limiting, highlight “Limiter” in the menu list using the arrow keys. Press “MENU/SEL” to choose this function. Use the arrow keys to select the limiter threshold in 3dB increments. Test it with a known signal to determine the maximum sound level you are comfortable with.
QUADRA Receiver: Body Placement Receiver Accessories Position the receiver on a belt, guitar strap, wardrobe, etc. so that the antennas are oriented vertically and not touching a metallic surface. Make sure the antennas are on the outside of thick or metallic costuming so the antenna whips will be out in the open. It is also good practice to keep the antenna whips from contacting a person’s body directly for maximum receive sensitivity. 12 • Replacement wire belt clip.

QUADRA Rack Mount Hardware The M4T is delivered with a partial set of rack mount hardware, including bolts, a rack ear, connecting flanges, antenna cable and front-panel handles. With two M4T units, there is enough hardware supplied in the delivery to connect the two units together, front-mount the antennas, and prepare the units as a complete assembly ready for mounting in a rack enclosure. 4. Remove the hex head bolts from the rear of both units right where they contact each other.
Digital IEM System 8. Attach the antenna wires to the antenna ports on the back of the transmitters. 9. Attach the supplied antenna connector protectors to the sides of the transmitters right behind the rack ears. Secure them with the supplied screws. Note that this item will fit tightly and is meant to deform slightly during installation. The dual set of M4T transmitters is now ready for rack mounting.
QUADRA Single Rack-Mount Instructions (using optional RMPM4T-1 kit) 1. Remove the plastic end-caps from the front of the M4T transmitter. Pry out the metal inserts on each side of the transmitter with a small screwdriver Plastic guards snap out from corners. Pry out the aluminum inserts on the side panel with a small screwdriver. 2. Attach the antenna cable to the rack ear with the supplied nut and lock washer.
Digital IEM System Firmware Updates As new versions of the firmware become available, updates are accomplished with a software utility and simple procedure. In many cases, updates must be made to both transmitter and receiver to ensure compatibility and provide the latest feature set. The software interface operates with Windows 2000, XP and Vista operating systems. Configuring the USB Port 1) Remove any previous LecNet2 installation from your computer. 2) Install LecNet2 software.
