  • Page 8: Introduction

    Precision soft dome high- and mid-frequency drivers provide ultra-high definition and an extremely wide, natural dispersion to create a vivid soundstage over a vast listening area. PMC’s ATL bass loading technology, teamed with its ten-inch carbon fibre LF piston driver, provides identical dynamics and deep, defined bass at all monitoring levels.
  • Page 9: Unpacking And Care

    Please Note: These units must be earthed Care and Service In normal usage PMC speakers should provide many years of trouble-free operation, but in the unlikely event that you suspect damage or failure has occurred do not attempt to repair the unit yourself as there are no user-serviceable parts inside.

    LF distortion. Consequently, the upper bass detail is not masked by harmonic distortion and the result is PMC’s characteristically fast, attacking bass, and outstanding clarity. ‘No other bass loading technology provides such resolution and tonal accuracy at all volume levels’...
  • Page 11: System Description

    PMC’s own cutting edge 400W, Class-D amplification module built-in to the rear of the cabinet. This bespoke module is a development of the amplifiers used in PMC’s active monitor and subwoofer products, and is designed for maximum fidelity, ultra-low distortion, and high damping that results in near-instantaneous stop/start control over the entire driver complement.

    Connections Caution To avoid potential damage, please ensure that the signal source is turned off before connecting or disconnecting your IB1S-A activated reference monitor loudspeaker. Audio Connections The electronically-balanced analogue line input accepts 3-pin male XLR connectors, wired with Pin-1 screen (ground), Pin-2 signal positive (hot), and Pin-3 signal negative (cold).

    However, the excellent stereo imaging which PMC monitors are known for is due, in part, to their wide dispersion characteristic, as shown on the right- hand image. To optimise the stereo imaging, PMC monitors should be angled so that their axes cross about 0.5 metres (2ft) behind the listening position (as illustrated below).
  • Page 14 Positioning & Alignment Attention should be paid to the effect of reflective surfaces such as side walls and objects in close proximity to the loudspeakers, as excessive nearfield reflections will blur the stereo imaging significantly and may introduce unwelcome colouration of the sound. Place the speakers so that their front baffles are well forward of any objects placed between them, such as computer display screens.
  • Page 15 Positioning & Alignment 5.1 Systems IB1S-A monitor has been designed for perfect multi-channel music or movie playback, and the following diagrams indicate the ideal layout for the speakers. • The constraints of room size and shape will often force some loudspeakers to be placed closer or further from the listening position than is ideal.
