1.1: INTRODUCTION

The Tannoy Reveal Digital range of near field monitoring speakers builds upon the success and worldwide reputation of the famous original Tannoy Reveal Active. Since the launch of the original Tannoy Reveal Active in 1998 there have been significant advances in digital speaker measuring techniques, acoustic CAD design and simulation, and precision manufacturing processes.

The Tannoy Reveal Digital range now provides greater bandwidth, significantly lower levels of distortion, smoother responses, more accurate phase control, and higher sensitivity levels; all within compact cabinet sizes. Also, much has been learnt about the near field listening environment - the effects of boundary walls, acoustic reflections from mixing console surfaces and the acoustic properties of often sparsely prepared PC/Mac post production editing situations.

The Tannoy Reveal Digital range of monitoring speakers can be optimised for far field, mid field and near/close field free space situations right through to far field, mid field and near/close field situations in difficult acoustic spaces such as meter bridge positions, adjacent to walls or reflecting surfaces and space restricted PC/Mac based sound editing environments.

Acoustic space environments are referred to as 4pi, 2pi and pi representing the solid angle in space (steradians) into which the speaker is radiating. These environments are frequently referred to as free space, half space and quarter space listening conditions . The type of acoustic space into which a speaker radiates, defined by nearby solid boundaries, affects the acoustic air load presented to the speaker and so the relative radiating efficiency at various frequencies. In different pi spaces the linearity of the amplitude response changes, especially within the band 50Hz to 800Hz.

Varying distances encountered between the monitors and the listener are generally referred to as far field (greater than 3m or 10 feet), mid field (2 to 3m or 6 to 10 feet), near field (1 to 2m or 3 to 6 feet) and close field (around 0.5m or 1.5 feet). The proximity of the listener to the speaker changes the way the listener perceives the sound balance from the speaker. At large distances from an acoustic source plane waves are perceived. At small distances from an acoustic source the waves appear spherical.

2.0: THE BASICS 2.1: UNPACKING AND VISUAL CHECKS

The Reveal 6D’s are packed in pairs and the Reveal 8D and 66D’s are packed singly. To remove the speakers from the carton without damage open the end flaps fully and bend them right back (remember they are packed in pairs). Turn the package upside-down on the floor and lift the carton vertically up to leave the speakers resting on their packing tray. Nothing on or in your speakers should rattle about. Inspect each speaker for signs of transit damage. In the unlikely event of this having occurred inform the carrier and the supplier. Keep all the packaging if damage has occurred, as this will show evidence of excessive handling forces. It is also a good idea to keep the packaging if possible for future transportation.

2.2: PRELIMINARY RECOMMENDATION

Initially we would like to give a word of warning on high sound levels, which these speakers are capable of generating over sustained periods of time. Levels over 95 dB for 8 hours per day can eventually cause permanent hearing loss. Because Tannoy monitors have very low levels of time, amplitude and frequency distortion it is not always obvious that the sound level is high while working with them.

For continuous exposure we recommend the occasional use of a sound level meter capable of integrating the sound level over a period of exposure according to noise control standards. This should be used just to check that noise levels are always within safety limits.

3.0: REVEAL D SERIES FEATURES

A set of DIP switches on the rear panel of each speaker can be set to choose the optimum speaker response for these real life and often difficult situations, so that the frequency response from the speaker is always substantially flat. We are not equalising the room modes due to standing waves or resonant structures, we are equalising the speaker to take account of the varying air load presented by the room and surrounding large structures such as the mixing desk.

The switches are arranged in groups according to their function and each switch can be set to the 'on' (down) or 'off' (up) position in various combinations to achieve a flatter, more balanced response within a wide variety of acoustic spaces and with far, mid, near and close field monitoring positions.

Figure 1 shows the range of equalisation available in the 50Hz to 800Hz region and also shows the degree of trim available in the bass, upper midrange and high frequency areas,

An A/V 80Hz high pass filter switch provides instant conversion to 5.1 and higher order systems where a separate subwoofer below 80Hz is required. Filter characteristics are according to the international standards for this setup. This response is also shown diagramatically in Figure 1.

Listening to well recorded male or female spoken word or vocals at the normal listening position is a good way to check and optimise the available settings. Difficult environments and variable listening distances produce varying degrees of boost from the flat position in the 50Hz to 800Hz area. Graphical representations of the responses available by setting the switches are shown below. The linear or flat response positions for the DIP switches are always clearly shown in the diagrams below and also on the rear panel of the speaker.

The Tannoy ActivAssist™ software package is available to help with the DIP switch settings. Using a standard laptop with the microphone and cables supplied in the pack, the performance of the speaker in a particular environment can be assessed and a recommended set of switches set up.

3.2: DIGITAL SPDIF INPUT

The input impedance is the SPDIF specification at 75 ohms and the 24 bit DAC supports 44.1, 48 and 96kHz sampling rates. Please use a high quality* SPDIF coaxial phono (RCA) cable to connect the source equipment (eg CD player, DAT/ADAT or PC sound card) to one of the speakers. Connect a second (phono to phono) high quality cable from this speaker to the second speaker of the stereo pair. Select whether each speaker converts left channel or right channel audio as appropriate using the switch adjacent to the SPDIF input connector. For true mono requirements set the switch to mono. If volume can be controlled from the source equipment, set the source equipment volume level to minimum and the speaker volume control to maximum (fully clockwise). If volume cannot be controlled by the source equipment (eg a simple CD or DAT etc) set the volume control on the speaker to minimum (fully anticlockwise) to prevent excessive sound levels. The volume control adjusts the analogue level after the DA converters to preserve the full digital dynamic range.

* In order to comply fully with EMC regulations, the SPDIF input and SPDIF thru should be connected using metal-shelled connectors and good quality shielded cable suitable for digital audio.

3.3: CONNECTING YOUR SPEAKERS

Having chosen an appropriate location for your monitors and arranged them accordingly, connect the power cord to the mains socket and turn the power on. The LED on the front panel will now glow red. Push the Tannoy logo on the front panel to operate the switch to bring the amplifier out of standby mode and into operational mode. Set the volume control on the rear panel to zero (fully anticlockwise). Connect the audio signal source (console output) to the input connector (combined XLR/jack socket) or SPDIF at the back of the monitor.

3.4: USER CONTROLS

A/V (80Hz): a switch to the bottom left of the bank of DIP switches sets the system high pass filter to either flat or –6dB at 80Hz. The 80Hz setting is used when the speakers are in combination with a subwoofer for low frequency effects such as Dolby Digital, AC3, DTS etc playback situations. For all other situations set this switch to flat. This response can be seen in Figure 1 above.

Left/Right/Mono: a switch at the bottom left of the bank of DIP switches sets the SPDIF DAC to sense the left, right or combined stereo information (mono) from the digital stream. Set the left hand speaker to ‘Left’ and the right hand speaker to ‘Right’ for 2 channel stereo, or to ‘mono’ for single speaker monitoring.

Analogue/Digital: a switch adjacent to the XLR/Jack combi socket selects whether the speaker is receiving a signal from the balanced/unbalanced analogue input combi socket, or, from the SPDIF phono (RCA) digital input. Both may be connected simultaneously but only one can be selected at any one time.

4.0: EQUALISATION POSSIBILITIES

Note: In the diagrams which follow, the corner frequency shown as 50Hz will vary according to the specification relating to the particular model which has been chosen. Please refer to the detailed specification section at the end of this manual for more details. Smaller models will have a slightly higher corner frequency and larger models will have a lower corner frequency. The diagrams have been prepared to make the visualisation of the EQ possibilities easier to understand. The transitions of the speaker amplitude response bewteen frequency bands will be gradual and not as sharp as the diagrams show. Note the +10dB and -10dB calibrations on the charts. EQ settings should never be at opposite extremes eg -8dB low mid contour with -2dB mids and +3dB highs.

There are 4 basic frequency bands that can be adjusted. The range of adjustment is purposely restricted so that although effective in the majority of environments, it is difficult to set the speaker to have a totally unacceptable response. A 'flat' setting means flat within specification as measured in an anechoic chamber, on axis, under free field conditions in the far field (3 metres away). The frequency bands are:

Bass Corner Frequency: The 'Q' value of the bass unit and cabinet volume alignment can be altered giving +3dB, flat, - 1.5, -3, and -4.5 dB relative to the -3dB point shown in the specification. This provides a degree of boost and cut in the 45Hz to 65Hz area. Figure 2 shows the range of adjustment available together with the DIP switch settings for the first 4 DIP switches. All other DIP switches are shown in the anechoic flat positions.
