FRONT CONTROLS AND CONNECTIONS
7
MASTER SECTION
(8) POWER ON/OFF SWITCH & LED
This switch turns the unit on and off and the LED indicator will light when the unit is on.
(9) ECHO EFFECT
This control adjusts the feedback/decay time of the internal Echo Effects DSP. Set this control slightly above minimum to emulate
room reverbs and adjust towards maximum for hall and stadium decay reverbs.
(10) AUX INPUT
The 1/4" Aux input jack can be used to add line level audio signals to the master mix. This signal level is affected by the Aux/Tape
control (12), L-R/Main Volume (15), Monitor Volume (16) and 5-Band EQ’s (18).
(11) TAPE INPUT
The Left and Right Tape Input RCA jacks allow cassette recorders, CD players, or MP3 players to be added to the master mix output.
These signal levels are affected by the Aux/Tape control (12), L-R/Main Volume (15), Monitor Volume (16) and 5-Band EQ’s (17).
(12) AUX/TAPE VOLUME
This volume control adjusts the signal level in the master mix of the Aux and Tape inputs. It is pre L-R/Main Volume (15), Monitor
Volume (16) and 5-Band EQ’s (17).
(13) EFFECTS SEND & RETURN
The Effect Send 1/4" jack provides a mono mixed signal output from each input channel to an external effects unit, external amplifier,
or recording device. The audio mix is adjusted by the EFF control of each channel. The signal output is not effected by the internal
reverb. The Effects Return input jack can be used to return the signal into the SPM-6300 or it can be used as another auxiliary input
for line level devices. The input signal can be adjusted using the Effects Return Volume (14) and also the output volume of the
external device.
(14) EFFECTS RETURN VOLUME
The Effects Return input signal can be adjusted using this control.
(15) LEFT-RIGHT / MAIN MASTER VOLUME
This control sets the level of the stereo left and right signal sent to the left and right Speaker Outputs (19) when the Power Amp
Selector Switch (18) is set to Left-Right. When the selector switch is set to Monitor-Main, this control adjusts the level of the Main
Speaker Output (19).
(16) MONITOR MASTER VOLUME
This control sets the level of the Monitor mix sent to the Monitor Speaker Output (19) when the Power Amp Selector Switch (18) is
set to Monitor-Main. This control is not active when the selector switch is set to Left-Right.
(17) STEREO 5-BAND GRAPHIC EQ
The dual 5-band graphic equalizers allow you to adjust the frequency response of the Left-Right outputs, or the Monitor-Main outputs,
allowing final tonal adjustments. These provide a maximum of 12dB cut or boost from the flat position for each frequency band; 60Hz/
250Hz/800Hz/2KHz/8KHz. The faders can be adjusted to easily eliminate feedback at the corresponding frequency or audibly color
the final mix.
(18) POWER AMP SELECTOR SWITCH
This switch selects which signals are sent to the internal power amps. When Left-Right is selected, the stereo signal from the L-R
Master Volume (15) is sent to separate Left and Right 5-Band EQ’s (17) and then continues to the Left and Right Speaker Outputs
(19). When Monitor-Main is selected, the signal from the Main Master Volume (15) is sent to the Main 5-Band EQ, then to the Main
Speaker Output, and the signal from the Monitor Master Volume (16) is sent to the Monitor 5-Band EQ, then to the Monitor Speaker
Output.
