Using the BY-PASS Input

The BY-PASS input allows the IN300 to function as a power amplifier, typically when connected to an A/V processor. Warning: Reduce the volume of the source connected to the BY-PASS input before initial use.

To activate BY-PASS mode, select it from the front panel or by holding the BY-PASS key on the remote control for 3 seconds. The display will show "BY-PASS". In this mode, all other functions are unavailable, and the IN300 operates solely as a power amplifier. Press the BY-PASS button once to exit this mode.

Bluetooth® Connectivity

Your appliance supports Bluetooth® for receiving audio signals from compatible devices like smartphones, tablets, and computers.

• First-time Association:
• Activate Bluetooth on your transmitting device.
• Select the Bluetooth (BT) input on the IN300; an unlock symbol [unlock symbol] ? will appear.
• Find and select your IN300 from the list of available receivers on your device.
• Once connected, a lock symbol [lock symbol] ? will appear.

All audio signals from your device will be transmitted to the IN300. The device remains associated until the IN300 is unlocked or switched off.

Association of another emitter: To pair with a new device after an initial association, switch the IN300 completely off to make it discoverable.

The quality of Bluetooth reception depends on the emitter's power and the distance between devices. For optimal quality, maintain a distance of no more than 5 meters.

USB Input (High-Resolution Audio)

The IN300 features a High-Resolution asynchronous USB Input (Type B). To use this feature, you may need to download the appropriate driver from the Atoll website: www.atoll-electronique.com/en/xmos-specific-driver-usb/. An explanatory note on installation is provided. This driver is not required for Macintosh computers.

To ensure optimal transfer of High Resolution files (24 bits/192 kHz), it is recommended to use a USB interconnect cable with ferrite cores.

Accepted Formats:

• Optical and Coaxial Inputs: 16-24 bits (44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz).
• USB Input:
  • DSD: DSD64, DSD128, and DSD256.
  • PCM: 16-32 bits (44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, 192 kHz, 352.8 kHz, 384 kHz).
