user manual NuQ series System Requirements Passive loudspeakers and switchable loudspeakers used in passive mode NuQ series passive loudspeaker enclosures require only one amplifier channel for correct operation, the frequency splitting between the low frequency driver and the high frequency driver being accomplished by the internal passive crossover network built into each enclosure.
user manual NuQ series Amplifier Considerations Turbosound NuQ series loudspeaker enclosures should be driven by high quality power amplifiers designed for true professional use. Such amplifiers will have balanced inputs, DC and RF fault protection, and well designed cooling systems for reliability. The ‘program’ power, listed in the loudspeaker’s technical specification, is the best guide to the size of amplifier required for general purpose applications.
user manual NuQ series Self-powered Loudspeakers The Class D amplifier modules fitted to the NuQ-8DP and NuQ-10DP self-powered loudspeakers comprise one amplifier channel rated at 500 watts continuous, powering both low frequency and high frequency drivers through a passive crossover network.
user manual NuQ series Loudspeaker connections Passive systems NuQ series passive loudspeakers are equipped with a recessed connector panel housing two Neutrik Speakon NL4MP connectors wired in parallel and serving as both input and loop out connections to additional NuQ series loudspeakers.
user manual NuQ series total impedance of 4 ohms. Never connect loudspeakers whose total combined impedance is lower than the amplifier’s recommended minimum load impedance.
user manual NuQ series Networking Capability NuQ series systems—these can be either passive or active loudspeakers operating with LMS series digital loudspeaker management systems, or self-powered loudspeakers, or a combination of both—may be connected together over a BvNet network, enabling realtime control and monitoring of multiple operating parameters from a central location with a PC running TurboDrive™ software, or even remotely via a VPN (virtual private network).
user manual NuQ series TurboDrive™ Quick Reference Setup The following is a quick reference setup guide for networked systems. For more detailed setup instructions please refer to the TurboDrive™ User Guide, available from our web site at www.turbosound.com To create a network of NuQ systems follow the steps below: 1. Install the TurboDrive software from the CD supplied or download from the Turbosound website 2. Install the drivers If you are connecting via RS232 there is no need to install drivers.
user manual NuQ series 4. Using USB Connect your computer to the BvNet interface using a USB Type A to USB Type B cable. External power is not required when using USB. CONTROLLER IN LINK CONTROLLER IN LINK BVNET INTERFACE IN LINK RS-232 USB USB 5. Connect network devices in a simple daisy-chain fashion with CAT5 type cables in the order you want them to appear in the devices window. 6. Launch the TurboDrive™ software On the first launch, the application will prompt for an authorisation code.
user manual NuQ series Loudspeaker Placement Choosing the best location When using any loudspeaker system certain room parameters will affect the resultant sound quality and coverage. For example, any boundary like a wall or floor will lift certain frequencies. If you are placing speakers in a corner, then a lift at the bass end is to be expected and it may sound rather ‘boomy’. This can be compensated for by moving the speaker or cutting low frequencies with an equaliser.
user manual NuQ series Calculating the sound pressure level at a known distance from the PA Sound intensity reduces rapidly as the distance from the source increases according to the inverse square law which, predicts that a doubling of distance will result in a reduction of ¼ the original, equal to a drop of 6dB, providing there are no reflections or reverberation. For every 3dB increase of speaker output you need a doubling of input power.
user manual NuQ series System Configurations The NuQ-8 and NuQ-10 two-way enclosures are passive loudspeaker systems. This means that they require only one amplifier channel for correct operation, the frequency splitting between the low frequency driver and the high frequency driver being accomplished by the internal passive crossover network in each enclosure.
user manual NuQ series System 2 – Stereo Passive setup with Bass Units and Active Crossover MID/HI FROM MIXER L R LEFT EQ BASS LMS-D24 POWER AMPLIFIERS MID/HI RIGHT BASS In this case an LMS-D24 is used to separate the bass and mid / high frequencies and feed them to the appropriate cabinets. This system can be scaled up with the addition of further amplifiers and processors.
user manual NuQ series System 3 – Stereo Bi-amped setup with Active Crossover HIGH FROM MIXER L R LEFT EQ BASS LMS-D24 POWER AMPLIFIERS HIGH RIGHT BASS Note: Bi-amp mode must be selected on the rear panel of the loudspeaker before proceeding with this setup. The LMS-D24 is used to separate the bass and high frequencies and feed them to the appropriate components within the enclosure. An additional pair of cabinets may be connected. NB: The EQ shown is for tuning the system to the room / venue.
