(9) LINE/PHONO INPUT SELECT SWITCHPlace this switch in the “up” position for line level inputs suchas from instruments, CD, players, tape machines, DATplayers, etc. Press the switch to the “down” position for aphono level input such as a DJ turntable.(10) TRIMThe trim control for the stereo input channels functions thesame as the control for the mono inputs.This control can beadjusted to accommodateinput signals from a widevariety of sources, from thehigh outputs from keyboardsor drum machines to thesmall signal outputs ofmicrophones. This widerange eliminates the needfor Mic/Line switching. Thetrim control adjusts the inputsensitivity from -∞ to -55dB.(5) AUX SENDThese are the same as forthe mono channels. Notethat a mono sum is takenfrom the stereo input.(11) BAL CONTROL. For amono input to the L or Rinput the function of thecontrol is the same as thePAN controls (6) of themono channels. However,when a channel is run instereo, this control functionsas a Balance control, deter-mining the relative Balanceof the left and right channelsignals being sent to the leftand right Master Mix buses.For example, with the Balance control turned fully clockwise,only the right portion of the channel’s stereo signal will berouted to the Master Mix.(7) CHANNEL GAIN CONTROLThis has the same function as the mono channels. See MonoInput Section.C O N T R O L S A N D C O N N E C T I O N S7(27)BACK PANEL(28)During rehearsals, experiment with the equalizer controls onvarious instruments, vocals and combinations of these mixedtogether to become familiar with various equalizer settings.(5) AUX ( POST ) SEND CONTROLThe Aux send is mono and post-EQ and post-fader and thesignal level sent to the AUX bus will be affected by thechannel fader setting. This configuration is ideal for almost alleffects send purposes. For example, when a fader level isadjusted, any reverb sent from that channel follows the fader.Otherwise, when the fader is pulled down, the reverb fromthat channel would still be audible. Most reverbs etc. internallysum the left and right inputs so that you can use the monoAux. You can also use this Aux send to feed inputs to a multi-track recorder or any other unbalanced line level application.(6) PANThe Channel Pan positions the output of the channel in thestereo field of the main mix. Its constant-power designensures there are no level discrepancies whether a signal ishard-panned, center-stage, or somewhere in-between.(7) CHANNEL GAIN CONTROLThe channel gain controls determine the output signal level tothe Master Mix bus. There is no PFL function on the SPM-835. In order to audition any single channel for proper gain,you can turn off the gain control of all the other channels (fullycounterclockwise), and set both the auditioned channel andMaster Mix control (17) to unity gain (0 dB).2. STEREO INPUT SECTION(8) L/R LINE INPUTSOn stereo input channels 5-8, the unbalanced RCA jack lineinputs are designed for stereo line-level signals such as thosefrom keyboards, drum machines, CD players, tape decks,samplers, or even turntables. However, these inputs can alsobe used as standard mono line inputs by connecting thesignal to the L or R line in. For the stereo inputs, the monochannel PAN (6) control is replaced by the BAL (Balance)control. See also BAL CONTROL (11) below.When using channels 5-6, 7-8 as stereo input channels, theleft signal should be connected to the L input and the rightsignal to the R input. These signals will be routed to the AUX,EQ and Channel Gain controls equally and will retain theirstereo separation. The AUX, EQ, BAL, and Channel Gaincontrols all function the same as those on the mono inputchannels. When a stereo signal is input to a stereo inputchannel, these controls will affect the left and right signalsequally.(8)(9)(10)(5)(11)(7)
