Introduction Thank you for purchasing the Yamaha i88X Audio/MIDI Interface. Connecting the i88X to a computer expands music production environments that utilize an audio sequencer on the computer. The i88X supports mLAN, a digital music network based on the IEEE1394 high performance serial bus and data protocol. The i88X makes it easy to construct sophisticated networks for IEEE1394 audio and MIDI signals without having to re-configure complicated cabling, as

Fundamentals of mLAN mLAN is a digital network for music that was developed based on IEEE1394, an industry-standard high-performance data communications protocol. Digital music environments that do not feature mLAN require dozens of cables for various devices and purposes, including MIDI cables and audio cables to route MIDI and audio signals. If you wish to make changes to such systems, you must physically disconnect and re-connect these cables. For example, adding another

Connecting External Devices CAUTION Before you connect external devices to the i88X, turn off the power to all devices. Also, before you turn on or off the power to the devices, lower the volume setting on all connected devices to minimum. Otherwise, electrical shock or damage to the devices may result. The following diagram illustrates a typical connection example. Refer to this diagram to connect microphones, musical instruments, a computer, and other external devicves. Electric guitar/ Mic

Wordclocks In a system that features multiple digitally-connected devices, all digital devices must be synchro- nized when digital audio signals are transferred from one device to another. Even if the devices use matching sampling frequencies, if their audio processing timing is not synchronized, they might not receive signals correctly, and audible noise, glitches or clicks may occur. Synchronization is achieved using a wordclock (a clock signal that synchronizes all digital audio signals i

About connections with external devices when using the i88X with a computer When using audio devices, musical instruments and computers at the same time, there is bound to be some noise in the system, the amount of which depends on the connections. Knowing how to minimize noise is extremely important when designing and setting up a studio. As advanced as the i88X is, it too is susceptible to noise. Various types of noise may be generated and recorded to your audio sequencer, depending on the

Connecting Musical Instruments and Microphones and Adjusting the Input Level Signals input at INPUT 1-8 jacks are routed to mLAN output channels 1-8 respectively. If you have selected any pair from channels 1/2 through 7/8 for monitor output, you can monitor the corre- sponding input signals from MASTER L & R and MASTER PHONES (page 17). This section describes connecting musical instruments and microphones to the INPUT 1-8 jacks and adjusting the level of input signals. mLAN mLAN INPUTS ANALO

Direct Monitoring Through the MASTER L & R jacks and the MASTER PHONES jack, you can directly monitor signals input at INPUT 1-8 jacks or COAXIAL or OPTICAL DIGITAL STEREO INPUT jacks. When an audio input signal, such as a guitar or vocal signal, is output through the computer, latency (delay) may occur. However, this Direct Monitoring function enables you to monitor a sig- nal before it is output to the connected computer, and thus avoids latency in the monitoring signal. If you wish to recor
