    STATUS

    Choose between ENABLED (default) or DISABLED to specify whether the input is enabled.

    AUTO SENSE

    Setting AUTO SENSE to SELECT allows you to specify that an input should be selected automatically when an audio signal starts on that input. To avoid unwanted switching between inputs due to gaps in the music, etc, the input must have previously been silent for at least a minute for a signal to select it.

    Selecting WAKE+SELECT will also automatically wake the I15 from standby, if necessary. OFF (default) will disable automatic switching on that input.

    While the SELECT option remains available, the WAKE+SELECT option is not available for the A1/Phono input if the MM15 phono preamplifier board is installed.

    VOLUME

    Choose between VARIABLE (default) or FIXED to specify whether the input should have variable or fixed gain.

    FIXED is 0dB gain, equivalent to volume setting 66, and will overrule MAXIMUM VOLUME in AUDIO SETTINGS.

    Selecting FIXED will show a loud-volume warning. Select YES to proceed or NO to cancel the fixed gain setting.

    Fixed gain functions as an SSP (Surround Sound Pass-through) allowing the I15 to be used as an amplifier in a multi-channel system setup

    INPUT GAIN

    Choose between: -30dB to -1dB, 0dB (default), or +1dB to +30dB to set the gain for the selected input.

    If the gain is set too high on an input clipping may occur.

    If an input is set to VOLUME FIXED, the INPUT GAIN is fixed at 0dB, and will show FIXED in the INPUT GAIN setting.

    AUDIO SETTINGS

    The AUDIO SETTINGS menu allows you to customise the balance and start-up volume, and the maximum and mute volume.

    BALANCE

    Allows you to adjust the balance between 00LR-9 (far left), 00LR00 (centred, default) and -9LR00 (far right).

    STARTUP VOLUME

    Sets the general startup volume to between 0 and 60. The default is 20.

    MAXIMUM VOLUME

    Set maximum volume limit between 0 and 99. The default is 99.

    MUTE VOLUME

    Sets the volume when unit is muted. You can choose between 0 (default) and 30.

    If the current volume is lower than the specified MUTE VOLUME, the volume will be set to 0 when pressing mute.

    GENERAL SETTINGS

    The GENERAL SETTINGS menu allows you to configure the general operation of the I15:

    SHOW INPUTS

    Choose between ALL (default), to show all inputs, or WITH SIGNAL, to show only inputs that have a signal.
