Signal input mode can be selected according to the following two needs: Balanced input signal (differential): Signal + Signal -, GND (ground). Unbalanced inputs (single-ended): - end and GND (ground) short circuit, the signal input from the + terminal. 3300 / 25V filter capacitor The output voltage regulation: 1. adjust the CV-ADJ potentiometer, according to your or LED, the output voltage is set to the voltage you need. Clockwise voltage is small, counterclockwise adjustable. 2. clockwise CC-ADJ potentiometer about 20 laps, the output current is set to a minimum, connected to the LED, CC-ADJ potentiometer to the required current. For charg, put the after the end of the, then receive the output, adjust the CC-ADJ to the current you need, (for charg must be used when the is fully charged, because the left The more charge, the smaller the charge current.

The Yamaha IM8 40-Channel Sound Reinforcement Console is a professional audio mixer designed for demanding live sound applications. The mixer features 40 mono input channels and 4 dedicated stereo input channels, each with a powerful 4-band EQ section and enough flexible routing to handle the most complex audio mixing scenarios. Every channel features a one-knob compressor for easy control over the dynamics of vocals and instruments, and until now, a feature only found on much more costly consoles. The output section features 8-bus routing to other mixers, monitors and recording devices and the matrix output provides alternate output wiring for just about any application. In addition to all these features, the IM8 series consoles feature a USB port for direct connection to PCs, and Cubase AI recording software is also included. The Yamaha IM8 consoles are well suitable for indoor and outdoor sound reinforcement in fixed or touring applications.
