4 VXP Series Operation Manual rev 3.0.0

1. Introduction

Designed and engineered in a unique partnership between Tannoy and Lab.gruppen, the VXP Series comprises a range of powered (active) loudspeakers for demanding professional and commercial sound applications. Each incorporates acclaimed Dual Concentric™ driver technology in tandem with on-board powering by Lab.gruppen’s IDEEA™ (IntelliDrive Energy Efficient Amplifier) module.

All VXP Series loudspeakers are designed to perform with very high efficiency and exceptionally low distortion, even when operating near peak output levels. At the heart of VXP Series is the latest genearation of Dual Concentric loudspeaker technology, which combines a high frequency driver and a low-mid driver on a common axis to create a true point source for all reproduced sounds. Dual Concentric eliminates the time alignment problems inherent with all separated driver enclosures, ensuring outstanding definition, detail and intelligibility at all points in the listening area.

Paired with Dual Concentric driver technology is the new IDEEA powering module from Tannoy’s sister company in Sweden, Lab.gruppen. At the heart of the IDEEA module is a patented Class D output stage capable of sustained high power levels with very low distortion – all with near 90% efficiency. A universal switching power supply accepts any mains voltage from 100 - 240 V (+/- 10%) at 50 Hz or 60 Hz through the appropriate IEC cord. The power control selector supports two operational modes: in Auto mode, the system turns on with signal present and turns off after 20 minutes of no signal input; manual mode allows the speaker to be turned on and off as required. Also provided is a switchable 90 Hz high-pass filter for use when adding a subwoofer. To ensure a long and trouble-free service life, IDEEA modules incorporate extensive features to safeguard internal circuits and the driver complement.

Within the VXP Series, system designers can choose from a variety of sizes, power levels and coverage patterns to suit particular requirements. For extended bass performance, models with the “.2” designation augment the Dual Concentric LF driver with a second matched LF driver. The “HP” designation indicates extended power handling capabilities, while the “Q” suffix indicates incorporation on the new Q-Centric Waveguide (QCW™) for applications requiring an asymmetrical coverage pattern. The QCW horn can be rotated in a matter of minutes, allowing placement of the 75 x 40 degree pattern with either horizontal or vertical orientation.

All VXP models are enclosed in rugged birch plywood enclosures, with larger models equipped with doublechamfered Integrip™ recessed handles for easy oneor two-handed carrying. Reflecting Tannoy and Lab. gruppen’s common reputation for reliability, all VXP Series loudspeakers are backed by a five-year warranty.

2. Unpacking and Visual Checks

Each Tannoy VXP Series loudspeaker is carefully tested and inspected prior to shipment. After unpacking, please inspect for any exterior physical damage, and save the carton and any relevant packaging materials in case the loudspeaker again requires packing and shipping. In the event that damage has been sustained in transit notify your dealer and the shipping carrier immediately.

2.1. Preliminary Recommendation

VXP Series loudspeakers can produce high sustained output levels for long periods of time. If users are in close proximity, these levels could lead to permanent hearing damage. Because Tannoy loudspeakers have a natural-sounding, flat frequency response and very low distortion, users may not be aware of the potential hazard. For continuous exposure to high levels, we recommend use of a sound level meter to ensure noise levels are within safety limits. The meter should be capable of integrating levels over a period of exposure in conformance with noise control standards.

4. Operation

All loudspeakers in the VXP range are integrated designs which include system specific EQ and protection circuitry, without the need for external amplification. For room equalization, delay and other commissioning or setup functions, we recommend you use a VNET SC1 or TDX1 Digital Controller. Below are examples of common set-ups:

4. Operation

4.1. Preliminary Recommendation

VXP products are equipped with Neutrik powerCON mains connectors which mate with the Neutrik NAC3FCA Cable connector, quick lock with a securing lever for power-in. This AC mains connector is supplied with each VXP product.

The IDEAA™ module in VXP loudspeakers has a universal power supply. It will operate on any AC mains supply from 70 V to 265 V (+/- 10%) at 50 or 60 Hz, although with reduced power output capability at the low voltage extremes 100-240 V (+/-10%). The module will continue to function down to 70 Vac, but with reduced output power capabilities. This allows continued operation even when using long, thin power cables, or when powered from portable generators that are unable to maintain full nominal voltage.

4.2. Auto and Manual Power Modes

VXP loudspeakers are designed to meet the requirements of the Energy Star 2.0 specification. The IDEEA module is highly efficient in operation, regardless of levels or program material, and has a STANDBY power consumption of less than 0.5 W. It also offers two modes for power on/off.

AUTO mode – This is the default mode as delivered. AUTO engages the Auto Power Down (APD) feature which puts the IDEAA™ module in STANDBY if no input signal is detected for a period of 20 minutes. The Auto Power On (APO) turns the module on in less than 2 seconds after a signal is present at the input.

MANUAL MODE – The power mode may be switched to MANUAL to disable the APD and APO functions. This allows use of an external power sequencer or manual control. Because of the very low idle current consumption, good overall efficiency is maintained even when the MANUAL mode is selected.

4.3. Cooling

Do not install this equipment in an enclosed space. Do not limit free ventilation and movement of air around the back panel. Ensure that there is at least 100 mm (4”) of space around all sides of the product for ventilation. VXP products do not have cooling fans; the highly efficient switch mode power supply and proprietary Class D output stage have less current draw and therefore require only the convection cooling provided by the rear panel heat sink.

4.4. LED Functions

Limit LED - When illuminated this indicates that the system is approaching clipping. An occasional flicker of the red LED on the loudest peaks is acceptable. If this LED remains red for more than the duration of brief dynamic peaks, or lights continuously then the system is being overdriven. If the red LED illuminates excessively:

•Reduce the input level (see interface panel)

•Reduce the output level of the mixer, or other source to the speaker.

Signal LED – The Green LED indicates that a useable signal is present at the input.

Power LED – StandBy - Red

Active - Green

Temp Prot. - Amber

4. Operation

4.5. Audio Connections

The signal input & link connectors are fully balanced. When connecting a balanced signal be sure to wire to the following standard:

SIGNAL	XLR CONNECTOR
Hot (+)	Pin 2
Cold (-)	Pin 3
Shield (GND)	Pin 1

In a standard balanced interconnection there are two signal conductors and a shield. The shield is normally referenced to ground at one or both ends. Many times the shield is lifted at one end, usually at the input to eliminate “ground loops” or noise. This should be done only as a last resort; although it will reduce hum, the shields can act as radio antennas and pick up radio frequency interference from the environment.

Multiple enclosures may be driven from a single audio source; simply plug the signal source output into the first XLR input socket, and patch that speaker’s XLR link to the next speaker’s XLR input socket.

4.6. Gain Structure

The VXP gain structure is designed to allow a low-level source device to drive the loudspeaker to full output. Maximum specified SPL will be achieved with a 4 dBu input signal. There is sufficient headroom in the signal path to accommodate input levels of 10 or even 20 dBu, with high quality compression engaged as needed to maintain sonic integrity without clipping. To avoid any compression, or when a lower SPL output is desired, the input attenuator on the rear panel can be used to reduce gain/sensitivity.

5.7 Limiters

The limiters are carefully set-up to preserve the loudspeaker’s dynamic headroom by allowing short term transients to pass; audible degradation will only become apparent when the limit indication is on constantly. The limiting functions will protect the amplifier from long term overheating by attenuating voltage to the drive units. If used irresponsibly (constant hard clipping) sound quality will be compromised. In extreme cases drive units may also be damaged.
