q INPUT Jack (INPUT)

This is the DS60-112s INPUT jack. The cable carrying the output signal from an external device, such as the DG-Stomps OUTPUT jack; the DG60FX-112s LINE OUT jack, etc. is connected to this jack. * Before making any connections, make sure that the power switch is set to OFF.
r Equalizer Controls (TREBLE, MIDDLE, BASS)
Controls the level of their respective frequencies. TREBLE (high frequencies), MIDDLE (middle frequencies), BASS (low frequencies). When set to 0, the tone will be flat, rotate the knob to the left (minus) to cut the frequency, and rotate to the right (plus) to boost the frequency.
w Volume Control (VOLUME)
Controls the volume of the speaker.
t Expansion Output Jack (SLAVE OUT)
The signal received via the INPUT jack is transmitted from this jack although with its impedance converted (the signal also bypasses the equalizer circuit). When adding another powered speaker unit, such as another DS60-112, connect the additional unit to this jack.
e Equalizer Switch (EQ ON/OFF)
This is the ON/OFF switch for the equalizer circuit (TREBLE, MIDDLE, BASS). Set to ON (>), the equalizer circuit is active and the three knobs r can be used to adjust their respective frequencies. Set the switch to OFF (?) if you want to produce only the direct sound created by the external device, with no additional alteration.
y Power Switch & Lamp (POWER)
This is the DS60-112s power switch. When the switch is depressed, the lamp next to the switch will light. * To protect the speaker from damage, always make sure that the Volume Control w is set to 0 before the power is switched ON/OFF.
