9 Illusonic IAP 2 Chapter 1 Introduction 7 1 Introduction 1.1 Foreword Conventionally in high end audio, people mix and match devices. They may use a DAC, an analog pre-amplifier, a phono stage, an equalizer, and a processor. Illusonic Audio Processors integrate these functionalities - because they belong together from a quality, technical, and usage perspective. The number of signal transmissions and conversions (AD, DA, digital clock sync) are minimized. Additionally, IAP 2 can calibrate each of its output channels with gain, delay, and parametric equalizers, to adapt to the room and loudspeaker positions. Depth/Immersion adds a new dimension to room adaptation, controlling spaciousness. The following pages give a more detailed overview over IAP 2 s features. I hope you ll enjoy countless hours of quality listening and entertainment! Yours truly, Christof Faller Founder and Owner of Illusonic

10 8 Illusonic IAP 2 Chapter 1 Introduction 1.2 How To Use This Manual The manual is structured to be read through from beginning to end. In case you read the manual only punctually, there are many pointers within the text, referring to related information and chapters. Detailed contents in the beginning and an index in the end help you find desired information quickly. You will find text and figures with additional information and insights placed in the info margin. 1 1 This text is in the info margin. This symbol indicates important information. General knowledge and tutorial information is indicated with this symbol.

11 Illusonic IAP 2 Chapter 1 Introduction IAP 2 Overview Inputs IAP 2 can connect to a variety of sources. There is usually no need for a device between the source and IAP 2. In addition to conventional analog and digital inputs, IAP 2 features a phono stage, USB audio, network media rendering, and four HDMI inputs. Analog, Digital Hi Res HDMI, USB, Network Phono Stage Outputs IAP 2 features two symmetric XLR and corresponding two RCA line outputs, which directly connect to power amplifiers or active loudspeakers. Its HDMI output connects to a TV or projector, if needed. Volume Control In order to be able to connect directly to power amplifiers or active loudspeakers, IAP 2 features volume control, implemented digitally. Volume control is applied just before the DACs using 32 bit floating point arithmetic, followed by a dithering process.

12 10 Illusonic IAP 2 Chapter 1 Introduction Room Equalization and Depth/Immersion Each channel features gain, delay, and fully parametric equalizers. These are usually used to calibrate the system and for room equalization. Calibration Depth Immersion Depth/Immersion adds a new dimension to adaptation of the sound system to the room. The specific room, loudspeakers, and loudspeaker positions determine how a room reacts to the sound. Depth/Immersion adds freedom to modify the perceived spaciousness beyond these traditional physical parameters. Tone Control While room equalization has the goal to mitigate dominant characteristics of your room, tone control is used to subjectively adjust the level of low and high frequencies. Not only bass and treble gain can be adjusted, but also the corresponding frequencies.

13 Illusonic IAP 2 Chapter 1 Introduction 11 Softwares The latest versions of IAP Controller and IAP Calibration softwares can be downloaded from the Illusonic web site. Both, Windows and OS X versions are available. IAP Controller presents all IAP 2 parameters for comfortable setup. IAP Calibration makes multi-point room measurement easy and helps setting up calibration related parameters (channel gain/delay, equalizers).

18 16 Illusonic IAP 2 Chapter 2 Getting Started Advanced Setup For reaching excellence of sound, it is often necessary to consider room acoustics and to adapt IAP 2 to the room and loudspeakers: If necessary, acoustically treat your room. Calibrate the loudspeaker setup for your central listening position by applying gain and delay trim to the loudspeaker signals (Chapter 5). 1 If desired, apply equalizers (Chapter 6) to the loudspeaker signals to: Attenuate overly strong low frequencies from loudspeakers positioned near walls or corners. Attenuate room resonances. Adapt the sound to the spectral response of the room. Calibrate loudspeakers behind a video screen. 1 When measuring your sound system, you can reproduce sound over each output channel individually in the Measurement sub-menu (Chapter 7). IAP Calibration software greatly facilitates measurement and calibration of your system (Chapter 8).

The figure above illustrates the Outputs menu and selection of its sub-menus. 1 The sub-menus are: GAIN TRIM FL 0.0 db For each output you can specify a gain trim value in db. 2 When measuring your sound system, you can reproduce sound over each output channel individually in the Measurement sub-menu (Chapter 7). IAP Calibration software greatly facilitates measurement and calibration of your system (Chapter 8). DELAY TRIM FL 0.0 ms / 0 cm / 0 in LFE GAIN 0.0 db For each output you can specify a delay trim value in milliseconds. 2 This sub-menu allows to adjust the gain of the low frequency effects (LFE) channel from 5.1 or 7.1 input sources. Off means that the LFE signal is silenced. 4 4 You may want to set LFE gain to Off, such that the LFE channel is not mixed into your main loudspeakers, putting less load on them. The LFE channel is defined as optional in the 5.1 standard. Thus, not considering it, gives a complete audio experience. SUBSONIC FILTER OFF Optionally, you can choose to apply a subsonic highpass filter, to reduce strain by subsonic frequencies on the loudspeakers. LIMITER ON By default, a limiter is active on the output channels ( On ), to make sure hard clipping does not occur. The limiters may be disabled ( Off ).

32 30 Illusonic IAP 2 Chapter 5 Menu: Outputs POLARITY FL NORMAL For each output channel the polarity can be inverted. This may be useful to check and correct polarity. LINE LEVEL NORMAL The analog output line level can be set between normal (RCA 2 Vrms, XLR 4 Vrms) and high (RCA 4 Vrms, XLR 8 Vrms). Unless your amplifiers need a high signal level, choose normal for better signalto-noise ratio. Professional active loudspeakers may need high line level.

33 Illusonic IAP 2 Chapter 6 Menu: Equalizer 31 In addition to fine-tuning your system with equalizers, as described in this chapter, use gain and delay trim (Chapter 5) to calibrate the level and gain for each loudspeaker). When measuring your sound system, you can reproduce sound over each output channel individually in the Measurement sub-menu (Chapter 7). IAP Calibration software greatly facilitates measurement and calibration of your system (Chapter 8). 6 Menu: Equalizer 6.1 Introduction For each loudspeaker you can use up to ten parametric equalizers. If you are not familiar with parametric equalizers, go to Section 6.3 to find out more. Some typical applications of parametric equalizers are: Loudspeakers Near Walls Low frequency gain boost due to loudspeakers near walls or corners can be corrected using Low Shelving filters with negative gain in db. Room Equalization Typically, Bell filters with negative gain in db and large Q factors are used to attenuate dominant low frequency room modes. Loudspeakers Behind Screen The low-pass characteristic of a screen can be compensated using a High Shelving filter with positive gain in db. 6.2 Equalizer Menu EQUALIZER SELECT EQUALIZER TYPE EQUALIZER PARAMETERS EQUALIZER COPY EQ TO 1 Sub-menus are selected by using Rotary (Turn).
