Because the PHONO3VB runs cool, it can be placed in many system locations without compromise. We do not recommend placing weights or other objects directly on the PHONO3VB. This may scratch or mar the chassis finish. Do not use harsh chemicals when cleaning the outside of your PHONO3VB. Single Ended RCA and input and output are available. You can place the PHONO3VB close to the turntable and minimize the length of the low level interconnect from your cartridge.
• VB power interconnect jack to interface with either the VBS1 or LNS1 power supplies • Dip Switches for Gain and Loading (Resistance and Capacitance) • Ground • RCA Inputs • RCA Outputs Switch Settings Input Resistor Load Setting Switches: A set of 9 switches are available next to each RCA input. These are used to setup the optimum Gain, Resistive Load and Capacitive Load for your cartridge. Please refer to the manual for your cartridge for optimum gain and RC loading recommendations.

• The PHONO3VB must be powered by either the VBS1 or the LNS1. If using the VBS1, please refer to the VBS1 User’s Guide for connectivity. If using the LNS1, please read the following • The LNS1 is designed to power Bel Canto VB equipped products only. Use of any cable other than the supplied power interconnect may damage either the LNS1 or VB equipped unit and will void any warranty. Certain non-VB equipped units can be factory upgraded.
