# Configuring the Server

Many application scenarios require specific server configurations. The default server options can be adjusted accordingly.

## Multi IO

The number of audio inputs and outputs can be defined before booting the server. Especially in multichannel applications - like in spatial audio - this is necessary:

s.options.numInputBusChannels  = 16;
s.options.numOutputBusChannels = 48;

// boot with options
s.boot;

// show all IO channels
ServerMeter(s);
