Use these individual channel level controls to create a mix of all the channels within the SP-828. NOTE: This control does not affect the level at the rear-panel Channel Output jack (#16). The channel signal will be 3dB down to both buses in the center-detent position. [. . . ] The headphone system follows these meters, so anything that shows on the meters can be heard in the phones. 10) Power/Solo Indicator This LED normally is Green, indicating that the unit is being supplied power (via the rear AC power jack). This lets the user know that the meters are now showing the Solo mix level instead of the L/R mix output. 11) L/R Master Level This rotary control sets the overall level of the L/R mix output to the rear-panel output jacks. The L/R mix is the sum of all of the channels, controlled by their individual Mix and Pan controls (#1 and #2). 12) Headphone Level This rotary control sets the overall level of the headphones. The headphones follow the Level Meters and normally monitor the L/R mix. If a Solo switch is depressed, the phones then monitor the Solo mix bus. 13) Phone jack This 1/4" TRS jack is used to connect headphones to the unit. The phones normally monitor the L/R mix, switching over to the Solo bus when a channel Solo switch is pressed. Best results are obtained with studio-quality phones with an impedance of 30 to 75 ohms. 5 sp828 manual. indd 6 REAR PANEL CONNECTIONS - INDIVIDUAL CHANNEL JACKS 8-9 14) XLR Input Jack This 3-Pin Female XLR jack is used to bring balanced signals into the channel. Normally, microphones are connected to this jack, and are selected by having the front-panel Line switch in the UP position, but hi-level signals can be accommodated by pressing the front-panel Line switch (#6). 15) Line Input Jack This 1/4" TRS jack is used to bring line-level balanced or unbalanced signals into the channel. If nothing is plugged into this jack, the XLR signals are normalled into the TRS circuit which allows the front-panel Line switch to do double-duty as a PAD switch. Input impedance is approx 15K ohms, so Hi-impedance instruments (guitars, bass) should not be plugged in here. No damage will occur, but the sound will not be optimum for those instruments. Use an outboard preamp or buffer amplifier for these types of instruments. 16) Channel Output This 1/4" TRS jack is used for the channel output. Signals from the channel can be fed into individual tracks for recording. This allows this jack to be connected to balanced and unbalanced inputs without concern. Use a balanced (2-wire w/shield) cable for all connections for best results. REAR PANEL CONNECTIONS - MASTER JACKS 2/22/05, 11:06 AM 17) Expansion In / Out jacks These 8-Pin mini-DIN jacks are used to tie SP-828 units together. When connected, the "Slave" SP-828 will send its signals to the "Master" SP-828.
