QUADRA 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.
Digital IEM System 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 capa bility 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.
QUADRA 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.
Digital IEM System Body Placement 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. For maximum receive sensitivity, it is good practice to keep the an tenna whips from direct contact with a person’s body.
QUADRA 2 Channel Operation In this mode, two channels are fed to the transmitter and are available at the receiver. Master(1,2) mode AUDIO CH. 1 2 MASTER VOLUME NOTE: the transmitter must be also in 2 Channel 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.
Digital IEM System 4 Channel Operation In this mode, all four audio channels fed to the trans mitter are available at the receiver. Master(1,2)+3,4 mode AUDIO CH. 1 2 AUDIO AUDIO CH. 3 CH. 4 MASTER VOLUME NOTE: the transmitter must be in 4 Channel mode for the receiver to work in this manner.
QUADRA Split 1,2 Operation Split modes allow you to use a single M4T transmitter running in the 4 Channel mode to send two different 2 channel stereo mixes to two different receivers or groups of receivers using a single radio frequency. Split 1+2 mode delivers audio channels 1 and 2 to the tall, thin knob and the lower concentric knob. The knobs can be set up to function in three different ways. Master(1,2) mode AUDIO CH.
Digital IEM System Split 3,4 Operation Split modes allow you to use a single M4T transmitter running in the 4 Channel mode to send two different 2 channel stereo mixes to two different receivers or groups of receivers using a single radio frequency. Split 3+4 mode delivers audio channels 3 and 4 to the tall, thin knob and the lower concentric knob. The knobs can be set up to function in three different ways. Master(3,4) mode AUDIO CH.
QUADRA Single Channel Operation The Single mode allows you to use one M4T transmit ter running in the 4 Channel mode to send up to four mono mixes to up to four different receivers or groups of receivers using a one radio frequency. This delivers the selected audio channel to the tall, thin knob as the master volume. Any one of the four audio channels sent to the transmitter can be routed to the master knob. The other three knobs have no function. M(2) MASTER VOLUME AUDIO CH.
Digital IEM System Additional Setup Options Pan Tune To select your RF operating frequency, choose Tune in the menu list, and press the MENU/SEL button. Here, you can choose between four operating frequen cies in the 4 Channel mode or one of the Split modes, or eight operating frequencies the in 2 Channel mode. To select your overall stereo balance and stereo pan ning for individual audio channels, use the arrow but tons to highlight Pan in the menu list.
QUADRA Limiter Treble Shelf This feature can be used in order to provide audio lim iting 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 ar row keys. Press MENU/SEL to choose this function. Use the arrow keys to select the limiter threshold in 3 dB increments. Test it with a known signal to deter mine the maximum sound level you are comfortable with.
Digital IEM System Factory Defaults This is used if you intend to reset the receiver back to factory settings. Select Defaults on the main menu and press MENU/SEL to select the two choices. Using the Presets Presets can be used to store all user settings includ ing Channel Setup, knob configuration, panning, and operating frequency. Five factory presets give you the most common starting configurations, while eight user presets allow you to customize your receiver and store those detailed settings.
QUADRA The first five presets, A - E, are permanently loaded with the most common channel setup and knob con figuration combinations: Factory A: 4-channel, M(1,2)+3+4 (see p. 9) Factory B: 4-channel, M(1)+2+3+4 (see p. 9) Factory C: 2-channel, M(1,2) (see p. 8) Factory D: split 1, 2, M(1,2) (see p. 10) Factory E: split 3, 4, M(3,4) (see p. 11) Factory presets can be modified by changing the knob setup, panning or any other parameter and then saved as a user preset for later recall.
