About external power amplifiers We recommend using power amplifiers that meet the following conditions. - With unbalanced inputs - With volume control bypass (or without volume control circuit) - Output power: 100 W (8Ω) or more • When using an external amplifier that does no have the volume control bypass, turn up the volume of the external amplifier enough and fix it.
