Placement and Initial Setup Because the S300i runs cool it can be placed in many system locations without compromise. We do not recommend placing weights or other objects directly on the S300i. This may mar or scratch the chassis finish. Do not use harsh chemicals when cleaning the outside of your S300i. IMPORTANT: Make all connections before powering your unit. Design Features The Bel Canto S300i represents a powerful statement in high performance audio integrated amplifiers.
S300i Single-Knob Control Functions Front Panel Control Knob: Input Selection Mode: The control knob is a continuously rotating control with a push-switch function. Pressing and holding the control knob for 2 seconds will take the S300i out of Standby and in to operating mode. The unit will come up in a soft mute mode. The operating input will be indicated for several seconds and then it will go to the volume control mode. To place the S300i in Standby mode press and hold the control knob for 2 seconds.
Remote Control Mute: (available only on the remote) Standby: Used to toggle the S300i into and out of standby mode. Standby hard mutes the outputs while keeping all circuitry running, maintaining optimum circuit performance. Before unplugging the S300i from mains power it is recommended to place it in standby first. Standby is indicated by the presence of 2 dashes on the display - - . The S300i starts up in Soft Mute. This level is 20dB below the displayed volume level.
Remote Control Volume Up: Volume Down: Increases the output level in 0.5 Decibel (dB) steps over a range of 0.0 to 100.0. Decreases the output level. STANDBY Pre In Vol + VOLUME CONTROL INPUT SELECTION Dac In Vol _ Mute CONTROLS HARD AND SOFT MUTE Conditioning The S300i’s sonic performance will start to stabilize after 100 hours of continuous power up. © 2006 bel canto design, Ltd. page 8 S300i User’s Guide 0906 Rev.
S300i Rear Panel Connections S300i Rear Panel Never Connect Either the Positive or Negative Speaker Output to Any Ground Contact! Always remove power before changing any cable connections to or from this product! Connecting any Speaker Output on the S300i to Ground will cause the amplifier to go into protection and could damage the amplifier and void the warranty. Inputs 1-4 accept standard line level RCA signal from any signal source. Input 5 is an optional USB DAC or MM Phono input module.
What to do if there is hum or ground noise The design of the S300i integrated Amplifier reduces the chance for ground loop induced hum and noise but we still recommend that you use shorter interconnect cables to the S300i inputs and con- nect all power cables to a common outlet box or power conditioner unit to reduce the possibility for ground current noise being induced into the audio signal path.
