The active versions of the Precision range incorporate powerful digital amplification
and advanced electronic processing that together take full advantage of the drivers?
capabilities. The result is greater dynamic range and low-frequency extension, higher
output levels, lower distortion and enhanced reliability.
From the front:
40mm MDF sculpted baffle ? stiff, heavy and rigid and minimises diffraction.
Recessed drive units flush with the baffle surface ? minimises diffraction.
10 point fixing maximises contact between drive unit and baffle.
Drive unit development using Klippell? analysis equipment to minimise offsets
and linearise the suspension components.
Cast chassis Tannoy Dual Concentric? point source constant directivity driver.
Effectively two drivers properly merged into one, with the HF mounted on the back
of the LF unit so that both drivers are on the same axis, As a result sound energy
is propagated from the same point and delivered through the centre of the low frequency
cone providing a true point source. This integrated approach provides a constant time
delay over the frequency spectrum offering better transient performance and sound
quality with better harmonic alignment than a displaced source monitor design. The
crucial benefit at the mix position is the delivery of a more natural and cleaner sound
with greatly enhanced intelligibility.
A key benefit of the Dual design is a very wide ‘sweet spot’ with an exceptionally even
response throughout the listening area and extraordinary transient response. This phase
accurate Tannoy designed drive unit has, for all these reasons, been the choice of
professional studio engineers for decades.
Tannoy SuperTweeterTM extends the amplitude response beyond 20kHz audibility to
50kHz to correct the phase response from 8kHz to 20kHz within the audible band. This
preserves the harmonic structure of sounds and the stability of the stereo image.
Smooth tweeter faceplate contours prevent diffraction and cavity effects.
From the side:
18mm MDF cabinet construction provides stiffness and minimises colouration.
Internal construction braces the sides and rear of the cabinet against the rear of the bass
driver to provide a rigid reactive mass for the moving cone assembly. Ensures fast tight bass
response and clear midrange.
Front baffle and rear panel tongued and grooved into the cabinet as a mechanical interlock
for safety if wall mounted.
From the rear:
Double insulated to prevent ground loops ? no safety earth required.
CSA/CE/CCC/CB full safety approvals including China.
Spare fuse in IEC mains connector.
On/Off mains isolator switch.
Substantial heat sinking for long term cool running and 24/7 reliability.
XLR and _? jack Combi connector for balanced input.
Switch adjacent to XLR selects digital or analogue input.
RCA input for SPDIF with 75 Ohm terminating impedance.
2nd RCA for SPDIF output for slaving a stereo pair.
Yellow LED indicator lights up when digital lock is achieved.
3-way switch selects which channel of the SPDIF stream is decoded,
marked Left/Right/Mono. Switching is post 2 channel DAC.
Trim/Gain control over +6dB/-12dB range reference 0dBV (0.775V) input
for full rated output.
Trim/Gain control works on SPDIF input post DAC.
Switch selection of 12dB/8ve 80Hz hi-pass filter for use with AV subwoofers.
First bank of 10 DIP switches controls LF alignment, mid/near/close field and
half/quarter/eighth space compensation.
Second bank of DIP switches controls mid band and HF shelving trim.
Note that the DIP switch flat setting is shown on the back panel artwork.
Small hole to the right of the right hand switch bank allows the factory set HF trim
on test to be fine trimmed by a service agent if a tweeter needs to be replaced.
Frequency response (1) 44Hz-51kHZ
