Model Sescom SES-3MIX. 1 x Passive XLR Mixer. Type Passive XLR Mixer. Since the SES-3MIX utilizes a passive design that doesn't require power, it needs no batteries or power adapter. As a result, it is optimal for mixing line-level signals or microphones that don't need phantom power, but it should not be used with high-impedance sources such as electric guitars.
