2. AUX input level control knob [AUX IN]
This adjusts the input level of the external equipment connected to the rear panel AUX IN jacks. The signal, whose level is adjusted by this knob, is mixed with the signal whose level is adjusted by the INPUT knob and thus output from both the PHONES jack and CASCADE OUT jack.
3. Peak LED [PEAK]
This will light when input is overloaded.
Should this light frequently, turn down the INPUT knob.

6. Input image position selector switch [ST/MONO]
Image position, of input signals from equipment connected to the rear panel balanced input connectors (XLR or PHONE) or the unbalanced input jacks (RCA), is selected by this switch. If switched to ST, the input signal will be output from the PHONES output jack or the CASCADE OUT jack, in stereo if switched to ST, or in monaural if switched to MONO.
7. Headphone jacks [PHONES 1 ~ 5]
