Nilfisk-ALTO GHIBLI 16 MIC/LINE Input, Mono Channel Insert, Stereo Input CH5~CH16, Low Cut

4.1 THE MIC/LINE INPUT 1

These are Channel 1 through Channel 4. You can connect balanced, low impedance microphones or a low level signal to the XLR socket. On the 1/4" Line jack you can connect either a microphone or a line level instru-

ment .

Note: You shall never connect an unbalanced microphone to the XLR socket if you do not want to damage both the microphone and the mixer. Also, it is not possible to simultaneously use both the MIC&LINE inputs on the same channel, use only one of them for the appropriate source on each channel.

- PHANTOM POWER +18 Volts

It is available only on the XLR input sockets. Please make sure the power switch is turned off before connecting a microphone to the XLR input.

4.2 MONO CHANNEL INSERT 2

Insert points are provided for mono MIC channels, which can allow you to patch external signal processing devices into signal path. When you insert a TRS jack in the insert socket, the signal will be taken out after the channel compressor, sent to an external processor, and returned into the channel strip immediately before the EQ section. Of course, the jacks used must be stereo (Tip Send/Ring Return).

Each stereo channel comes with two unbalanced line level inputs on 1/4" TRS jacks, which are used to connect left and right input signals. Use the LEFT input when connect a mono input signal to the STEREO INPUT. The last two stereo channels feature an original and exclusive double stereo input for each stereo channel. This feature allows you to connect two stereo sources at the same time for each stereo channel, enlarging the real number of signals you can manage at the same time.

4.4 LOW CUT 4

By pushing this switch you will activate a 100Hz low frequency filter that provides a precise cut for frequencies under 100Hz. You can use this facility to reduce the hum noise infected by the mains power supply, or the stage rumble while using a microphone.

4.5 THE TUBE SOUND COMPRESSOR SWITCH 5

The TSC switch (on the first 4 channels) activates the TUBE SOUND COMPRESSOR and let you choose between Compressor and De-esser functions. The two yellow LEDs show the amount of compression applied to the input signal. Two algorithms are provided, one for soft compression with a threshold level of 0dB, and one for hard limiting with a threshold level of around +10dB. This dynamic processor works on the very entry stage of the channel and it can avoid also the channel clipping, maintain the best signal-to-noise ratio. The compression algorithm applied to the sound is shown by two yellow LEDs.
