Connection Cable Stereo 1/4” phone plug Stereo 1/4” phone plug Mute On/Off Effect On/Off B A Names of Things and What They Do Names of Things and What They Do After connecting two SA-300s together with one or two audio cables (1/4-inch phone type), you can easily play back high power sounds (350 W + 350 W) in stereo. 6. STEREO LINK IN Jack When using Stereo Link, the audio output by the STEREO LINK OUT L or STEREO LINK OUT R jack on the other SA-300 is input here. You can use it as an external input jack also. Input level is 0 dBu. * All Channel 4 LINE jacks function as mono inputs when the STEREO LINK IN jack is in use. 7. STEREO LINK OUT Jacks (L/R) Connect this jack to the STEREO LINK IN jack on the other SA-300 when using Stereo Link. If you are not using the SA-300’s speakers, but using external amp speakers instead, the output from the left or right channel is taken here. When the STEREO LINK OUT L jack is used, the left channel audio is not played through the SA-300’s speakers. In the same manner, when the STEREO LINK OUT R jack is used, the right channel audio is not played through the SA-300’s speakers. Output level is 0 dBu. * Signals output from these jacks are not routed through the MASTER section (EQUALIZER, LOW BOOST, WIDE, VOLUME). For further instructions on connecting with Stereo Link, refer to “About Stereo Link” (p. 15). LINE OUT 8. LINE OUT Connectors/Jacks Mixers, recording equipment, and other such devices are connected here. Nominal output level is +4 dBu. This section includes balanced output compatible XLR type connectors (left and right stereo output) and 1/4- inch phone jacks (stereo output). You can use the XLR type connectors and the 1/4-inch phone jacks simultaneously. Output is in mono when only the left 1/4-inch phone jack is connected. 9. GND LIFT Switch Using external equipment connected to the LINE OUT connectors may result in generation of the “hum” of loop ground noise. If this occurs, you may be able to mitigate the problem by sliding this switch. Normally, this is set Pin 1 is disconnected from the SA-300’s ground. Pin 1 is connected to the SA-300’s ground. 10. SPEAKER Jack Use this jack to output sounds to the SA-300W Use the special connection cable included with the unit to connect to the SA-300W’s INPUT jack. This provides an even more powerful low end to the sound. Turn off the power on the SA-300 before connecting or disconnecting cable. • Connect only the SA-300W. Never connect any other equipment. • Be sure to use only the connection cable included with the unit to connect the subwoofer. Do not use ordinary audio cables. 13 Making the Connections Refer to the figure shown below to connect the SA-300 and the other equipment. fig.02-01 * To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections. * Before making any connections, set the SA-300’s MASTER VOLUME knob to “0.” * Use only the specified expression pedal (EV-5, etc.; optional). By connecting any other expression pedals, you risk causing malfunction and/or damage to the unit. * When connection cables with resistors are used, the volume level of equipment connected to the inputs may be low. If this happens, use connection cables that do not contain resistors, such as those from the Roland PCS series.

By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices. 1. Make sure that all volume controls on the SA-300 and connected devices are set to 0. 2. Turn on all the devices connected to the SA-300’s input jacks (CH 1 through CH 4). 3. Turn on the SA-300. 4. Switch on any equipment connected to the SA-300’s LINE OUT jacks. 5. Adjust the volume levels for the devices. 6. Before switching off the power, lower the volume on each of the devices in your system and then Turn Off the devices in the reverse order to which they were switched on. * If you need to turn off the power completely, first turn off the POWER switch, then unplug the power cord from the power outlet. Refer to “Power Supply” (p. 6). * This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required before the unit will operate normally. For protection from sudden big sound, always make sure to have the volume level turned down before switching on power. * Even with the volume all the way down, you may still hear some sound when the power is switched on, but this is normal, and does not indicate a malfunction.
