INTRODUCTION Thank you Thank you for purchasing a product from the i-Series from EM Acoustics. The i-Series products have been carefully designed and rigorously tested to ensure years of flawless operation and unprecedented sonic quality. Designed primarily for discreet installation use, the i-Series products find applications from cafes and bars through to museums, nightclub infills and themed attractions.
PRODUCT RANGE OVERVIEW i-1 Ultra-Compact Satellite Loudspeaker The i-1 is a compact, satellite mid/high loudspeaker, designed for a wide variety of discreet sound reinforcement applications from museums and themed attractions through to infills in nightclubs and bars. It contains a single 4” (102mm) titanium cone drive unit, with integral passive circuitry for unprecedented sonic performance from an enclosure type where compromises are usually made.
i-8 compound isobaric subwoofer The i-8 is a subwoofer designed to create the depth and authority in low frequencies that is normally associated with large systems, but in a compact package for ease of installation. Consequently, the i-8 has a frequency response down to 35Hz yet is small enough to be concealed underneath sofas or in small wall cavities.
SYSTEM SET-UP Safety Considerations Loudspeaker systems are potentially dangerous objects if used incorrectly. Please ensure that you read this section fully, and contact EM Acoustics or your local dealer should you be in any doubt over correct operation procedures. Professional loudspeaker systems are capable of producing damage-inducing sound pressure levels, and hence care should be taken when setting your system up, particularly when it comes to loudspeaker placement within a venue.
personnel following safe working practice. Should you be in any doubt whatsoever, please contact your local dealer who will be able to refer you to a suitable rigging company.
MOUNTING & RIGGING OPTIONS Rigging Hardware & Accessories The i-Series loudspeakers have a range of integral rigging hardware to enable usage in a wide variety of ways. The i-1 is supplied with four M5 fixings (one on each side of the enclosure) and a steel yoke. This steel yoke attaches to either pair of fixings to provide pan & tilt options.
Attachment and Adjustment of the YK-i1 yoke The i-1 ships with the YK-i1 yoke attached in the normal operating plane. Should you wish to rotate the yoke (for example to utilise the trapezoidal enclosure shape to fit the i-1 closer into a corner), remove the two countersunk M5 machine screws in the enclosure, and remove the M5 socket-head bolts holding the yoke in place. The yoke can then be rotated and the bolts reinstated in the alternative points.
Attachment of the YK-i2h horizontal hanging yoke With the i-2 lying on its side, remove the two countersunk M10 fixings in the ends of the enclosure (marked “A” in Fig 1) and put them in a safe place. Position the YK-i2h over the enclosure, insert the knurled plastic knobs into the holes and tighten securely. There are three possible positions for an attachment device – only the central point (marked “B”) should ever be used by itself.
Installation of the DA-1 Power Amplifier Module The i-12 subwoofer can accept the EM Acoustics DA-1 digital power amplifier module. One DA-1 is used to drive one i-12, and in this configuration the DA-1 runs in two channel mode, with each pair of drive units driven by one channel. To install the DA-1, lie the enclosure on its front. Using a 4mm Allen Key, carefully undo the six M5 socket head bolts holding the connector panel door in place on the rear of the enclosure.
