Introduction
Thank you for purchasing Tannoy SGM-series monitors. These are professional
mid-field reference monitors which provide unrivaled musical articulation and
outstanding dynamics and accuracy. Using advanced dual concentric drivers,
they offer the advantages of point source operation in a very cost-effective
design. The attractive wood panel cabinet and front panel contribute to their
excellent acoustic performance. Due to the point source operation, they will
perform
equally well in both landscape and portrait orientation.
This quick start guide is intended to provide the user with some useful advice
on how to install and use the loudspeakers, as well as technical information
about how the system is designed and its detailed specifications. We hope you
get the best results from your monitoring system.
Once you have set up your new monitors as described in this document, please
register your product online at www.tannoy.com – this
does not limit your legal rights.
Unpacking
To get the speaker out of the carton without damage, open the flaps fully and
bend them right back. Turn the package upside-down on the floor and lift the
carton vertically up to leave the speaker resting on its packing tray.
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 force. It is also a good idea to keep the carton for future
transportation.
Caution
These monitors are capable of generating high sound levels over a sustained period of time. Because of their low levels of distortion, it is not always obvious that the sound level is high when working with these monitors. Please be aware that exposure to excessive levels over a sustained period of time can lead to permanent hearing damage.
Operation
Consult the product specification section within this manual as this clearly
shows the acceptable power range for amplifier matching to your speakers. As
with all loudspeaker systems, the power handling is a function of voice coil
thermal capacity. Care should be taken to avoid overdriving any amplifier, as
this will cause output overload resulting in ‘clipping’ or distortion within
the output signal. This can cause damage to the speakers if done for any
extended period. Generally an amplifier of higher power that is running hard,
but free of distortion, will pose less risk of damage to the loudspeaker than
a lower power amplifier continually clipping. Remember also that a high
powered amplifier running at less than 90% of output power generally sounds a
great deal better than a lower powered example struggling to achieve 100%.
Always use the best quality of cable available within your budget.
High quality audio signals passing from the amplifier to the loudspeaker are
unusual in their demands on the cable. Wide dynamic range and wide bandwidth
information has to coexist with the ability to transmit peak currents of at
least 10 amps, without incurring any loss or signal impairment. We would
recommend that you always keep the cable runs the same length for each
speaker. Remember that cable construction can affect the sound quality so be
prepared to experiment to find a cable that suits your ear and audio system.
Single Wire Mode
First link the HF+ terminal to the LF+ terminal and HF- terminal to the LF-
terminal, using the links provided in the accessories pack.
The positive (plus) terminal on the amplifier left channel (marked + or
coloured red) must be connected to the positive HF terminal on the left
speaker. The left speaker is the one on the left as you look at the stereo
pair from your listening position. The negative (minus) terminal on the
amplifier left channel (marked – or coloured black) must be connected to the
negative HF terminal on the left speaker.
Repeat this connection process for the right speaker. Remember that the
positive (+ or red) on the amplifier must be connected to the positive (+ or
red) on the speaker and the negative (- or black) to negative. Select a signal
source, such as a CD player, switch on the amplifier and slowly turn up the
volume control to check that both loudspeakers are reproducing bass and treble
information.
Earth Connection
To optimise performance further, use a shielded or screened loudspeaker cable in order to reduce unwanted radio frequency interference. The screening termination should be connected to the earth or ground (white) terminal on the loudspeaker and to the ground or earth connection on the amplifier. Alternatively, if you are not using a screened loudspeaker cable but wish to utilise the earthing facility, run a single cable between the loudspeaker and amplifier earth terminals.
Bi-wire Mode
Please note in bi-wire mode that the link cables should not be used.
Best results will be obtained with a specially designed bi-wire speaker cable.
If your amplifier is not equipped with two sets of output terminals, twist the
Left LF+ (positive) and the Left HF+ (positive) together at the amplifier end
of the cables. Connect these to the amplifier Left channel positive terminal
marked + (plus) or coloured red.
Twist the Left LF- (negative) and the HF- (negative) cables together and
connect them to the amplifier Left channel negative terminal marked – (minus)
or coloured black.
At the loudspeaker end, connect the cables labelled Left LF+ and Left LF- to
the left hand loudspeaker LF terminals, ensuring that you note the polarity
markings on the cable sheathing. Then proceed to connect the Left HF+ and Left
HF- to the HF terminals on the same loudspeaker.
Repeat this process to connect the right hand loudspeaker to the amplifier
right channel output, once again ensuring that polarity is correct throughout.
Bi-amp Mode
Bi-amping extends the principle of bi-wiring one stage further.
In this connection option, separate power amplifiers are used for bass and
treble signals in each loudspeaker. Four mono (or two stereo) amplifiers of
the same type are required for a stereo pair of loudspeakers.
If two stereo amplifiers are used, it is recommended that one amplifier supply
bass information to left and right loudspeakers and the other, the treble
information. It is important not to use the link cables on the terminal panel,
otherwise amplifier damage may result.
Operation
Installation
When choosing a suitable location for the monitors, bear in mind that the
physical mounting of loudspeakers can have a large influence on performance.
For best results, the monitors should be mounted on a rigid structure,
supported on pads making contact with the laminated panel. Self-adhesive foam
pads are provided with the loudspeakers for that purpose. If you intend to
arrange the monitors in landscape format, detach the whole pad from the
backing paper and stick it on the large side to become the bottom of the
cabinet;
for portrait arrangement the pad is pre-cut so that one half can be easily
detached to match the smaller size of the bottom panel.
We recommend location of the monitors so that the drive units are toed
inwards, with their axes oriented towards the listening position.
The distance between the two speakers should be 2 to 3 metres, depending on
the monitoring position. The distance between the monitoring position and each
speaker should be slightly greater than the distance between the speakers. If
the speakers are placed too close to each other, the full stereo image may not
develop. On the other hand, if you place them too far apart you will notice a
hole in the middle of the stereo image.
Ensure that the console position does not obscure the direct sound radiation
from the Dual Concentric drive unit when sitting down.
The engineer and producer should have a clear, uninterrupted view of the
monitor loudspeakers.
Adjustment
Each loudspeaker model features two controls labeled Treble Energy and Treble
Roll-Off, and the SGM 15 has an additional control called Presence Energy.
These allow the high frequency response to be tailored to your listening
environment.
To make adjustments, each speaker should be operated one at a time in mono.
Pan the output from your source audio so that the full signal passes only to
the left or right speaker. The Treble Energy control increases or decreases
the HF driver over its entire frequency range from 1 kHz to 20 kHz, while the
Treble Roll-Off only affects the highest frequencies above 5 kHz. Presence
Energy boosts or cuts frequencies
between 1 and 5 kHz.
All controls should be set to the ‘Level’ position initially. If the sound is
too bright or dull, the Treble Energy can be used for broad adjustments. After
this setting has been established, further fine tuning with the Treble Energy
(and Presence Energy for the SGM 15) can be made as necessary. Changes to each
control can be fairly subtle and may not be heard at all if the audio being
monitored has little energy in the spectrum being adjusted. Keep in mind that
speaker
positioning and room acoustics also affect a speaker’s response.
Servicing
Cleaning the cabinet
To remove marks and scuffs, use a medium soft brush. If necessary, a little
warm water and detergent can be used, but under no circumstances use a solvent
or abrasive cleaner. The surface will change colour when wet but will return
to normal when dry.
Dual Concentric driver removal
Before any servicing operation, the amplifier should be disconnected from
signal input and mains power. Lay the cabinet on its back, taking care to
protect the rear plate. Remove the four hexagonal bolts and set aside. Ease
the driver from the front of the cabinet, taking care not to mark the front
surface.
Use a piece of stout cardboard to lever against if necessary. Remove the
driver and disconnect the internal wiring, taking care not to damage the
moving parts of the LF driver.
To refit the driver, connect the cables from the wiring harness to the LF (red
+ve and blue -ve) and HF (white +ve and black -ve) terminals.
Fit the driver into the mounting hole, fasten the bolts finger tight and then
progressively torque them down so that the driver seats evenly.
Drive unit servicing
The HF unit may be fitted with a new diaphragm assembly. With the driver face
down, release the three bolts securing the HF assembly and lift the HF unit
vertically upwards and away from magnetic attraction caused by the LF magnet.
Replace the diaphragm – it is self-centering – taking care to align the parts
correctly.
To refit the HF unit, hold it about 30 cm vertically above the LF magnet in
both hands while resting on your elbows. Slide your elbows apart and lower the
HF unit onto the back of the LF magnet. As the HF unit gets close to the
magnet you will feel the magnetic fields repelling. Align the fixing holes and
secure with the bolts, tightening down evenly. Do not tighten the bolts
finally until you are sure the HF unit is seated correctly and the two magnet
systems appear parallel.
The LF unit may be re-coned in the normal way. Use only the parts and adhesive
supplied in the re-cone kit.
Checking the unit
The whole unit can be checked using a sine wave generator connected to the
amplifier. A high quality, low distortion (preferably a beat frequency)
oscillator will be required to check for any buzz and rattle noise generated
by the drive unit. Testing the whole unit has an obvious drawback in that, in
the case of any defect it may be difficult to determine whether the drive unit
or the amplifier is faulty. In which case each part would have to be checked
independently, meaning that the drive unit should be removed (refer to above).
If for whatever reason the amplifier needs to be removed from the cabinet,
care should be taken to remove only the relevant screws (there are 8 mounting
screws, 2 on each side of the plate).
