Main Features

The SA-300 is a lightweight yet powerful stage amp, which functions as a combo amp while featuring full 2.1-channel stereo compatibility.

High Power

This combo amp has an output of 350 W (75 W + 75 W stereo, 200 W subwoofer).
4-Channel/Full Stereo Input Compatibility
The SA-300 features four input channels, all of which handle stereo input. Additionally, all are compatible with microphones as well as line-level equipment. The SA-300 also provides phantom power for two mic inputs.

Simple Setup

The mixer, amp, and speakers are integrated into a single unit, eliminating the need for complicated and bothersome cable connections.
Light, Compact, and Extremely Portable

This lights when the subwoofer is connected to the SPEAKER jack. While the indicator is lit, the low-frequency response with the subwoofer (SA-300W) connected is modified accordingly.

Jack Panel

fig.01-02

Inputs (CH 14)

1. MIC Jack
Connect a microphone here. For balanced input, you can connect to the TRS 1/4-inch phone jacks and XLR type connector.

fig.01-03

Supplying phantom power to mics that do not require it or supplying it to other devices may cause such equipment to malfunction. Always be sure to turn the switch off before connecting. To protect the circuitry, the channel output is muted momentarily after the PHANTOM switch is turned on or off. Phantom power is supplied only when a microphone is connected to the XLR connector in the Channel 3 and/or Channel 4 MIC jack section. Do not connect or disconnect connectors while the phantom power is turned on.

3. LINE Jack

Connect keyboards, CD players, and other line-level devices here. These are stereo inputs; mono input is available by connecting to the left jack. These connectors are compatible with line-level input (20 dBu). Channels 3 and 4 also feature RCA phono type inputs. In addition, you can input to both the RCA phono type and 1/4-inch phone jacks simultaneously. * All Channel 4 LINE jacks function as mono inputs when the STEREO LINK IN jack is in use.
2. PHANTOM Switch (CH 3, CH 4)
This switches the phantom power on and off. When connecting a microphone that requires phantom power (such as condenser microphones), switch this to ON.
Set this to OFF when connecting mics that do not require phantom power or other devices. Use the following sequence when connecting mics that require phantom power: 1. Turn the PHANTOM switch off. 2. Connect the mic. 3. Turn the PHANTOM switch on.

FOOT SW (FOOT SWITCH)

4. ANTI-FEEDBACK SWEEP Jack
You can connect a momentary-type foot switch (optional BOSS FS-5U or FS-6) and operate the automatic feedback frequency detection with your foot. Holding down the foot switch for one second or longer starts the automatic feedback frequency detection. Based on the results of this analysis, the microphone and environmental characteristics are compensated for automatically, making it difficult for feedback to crop up. * Set the FS-5Us polarity switch as shown below.

fig.01-10

* When connecting only one foot switch using a connection cable with a 1/4-inch phone (mono) plug, only the mute can be switch on and off. In that case, connect the switch with an FS-5L. * When an FS-5U (momentary type) switch is used for switching the mute on and off, the mute is switched on only while the switch is held down.

fig.01-04

Set the polarity switch as shown below.

Using a connection cable to connect foot switches (optional BOSS FS-5L and FS-5U), you can then use the FS-5L (latch type) switch to switch the mute on and off, and use the FS-5U (momentary type) switch to turn on and off the effects (reverb or delay). Mute On/Off When the FS-5Ls indicator is lit, the mute function is switched on, and the output from the speakers and headphones, as well as from LINE OUT and STEREO LINK OUT is muted. Effect On/Off The effect is alternately switched on and off each time you press the FS-5U.
Effect On/Off Mute On/Off

STEREO LINK

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.

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 1/4inch 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.

fig.01-06

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-300s 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-300s speakers. In the same manner, when the STEREO LINK OUT R jack is used, the right channel audio is not played through the SA-300s 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).

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 to OFF. ON: Pin 1 is disconnected from the SA-300s ground. OFF: Pin 1 is connected to the SA-300s ground.

SPEAKER

10. SPEAKER Jack
Use this jack to output sounds to the SA-300W subwoofer. Use the special connection cable included with the unit to connect to the SA-300Ws 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.

* 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-300s 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.
Switching the Power On and Off
Once the connections have been completed, turn on power to your various devices in the order specified. 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-300s input jacks (CH 1 through CH 4). 3. Turn on the SA-300. 4. Switch on any equipment connected to the SA-300s 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.

About Setting the Volume

To obtain the best sound from the SA-300, set the volume level using the following procedure.

fig.02-04

1. Use the INPUT SELECT buttons for CH 1 through CH 4 to switch the input sensitivity in accordance with the connected devices (microphones or line-level equipment). 2. Use the CH 1 through CH 2 VOICE ENHANCER buttons, REVERB/DELAY knobs and the CH 3 through CH 4 REBERB knobs to adjust the tone to your liking. 3. Operate the CH 1 through CH 4 volume knobs to adjust the volume level for CH 1 through CH 4. * If the sound is distorted (when level indicator 0 dB is lit), adjust the volume either with the VOLUME knobs (Channels 14) or the volume knobs on devices connected to the inputs (Channels 14). At this point, balance the volume levels of Channels 14.

fig.02-051

4. Use the EQUALIZER knobs (LOW/MIDDLE/HIGH), LOW BOOST button, and WIDE button to adjust the tone to your liking. 5. Use the MASTER VOLUME knob to adjust the overall volume level. 6. Set up the ANTI-FEEDBACK if necessary. (p. 16)

About Stereo Link

You can easily play back high power sounds (350 W + 350 W) in stereo by connecting two SA-300s together with one or two audio cables (1/4-inch phone type). This function is called Stereo Link. The SA-300 features a stereo mixer function, which enables you to output either left or right channel signals from the STEREO LINK OUT jack. Connecting the SA-300s according to the instructions below allows you to play sounds in stereo.

Example 1

Up to four input devices can be connected.

fig.02-06

Example 2
This arrangement lets you play in stereo, making maximum use of the two SA-300s mixer functions (with eight inputs). All Channel 4 LINE jacks function as mono inputs.

About the Volume and Tone Settings
Adjust the R and L volume levels separately using their MASTER VOLUME knobs. You can adjust the EQUALIZER (LOW/MIDDLE/HIGH knobs), LOW BOOST, and WIDE independently for the L and R sides. Basically, they should be set to the same positions, but you can adjust each one as necessary to suit the needs of a particular setup. The EXP PEDAL/REMOTE SW jack affects only the input signals to the SA-300 to which the expression pedal or the foot switch is connected.

Relationship Between Anti-Feedback Functions and Buttons
ON/OFF Button: SWEEP Button: Switches Dynamic function on and off Activates the Safety Margin function
Reducing Acoustic Feedback with the SA-300 (Anti-Feedback)
The SA-300 includes the following three built-in functions, which allow you to achieve an acoustically stable system that automatically controls the occurrence of feedback and makes it more difficult for feedback to arise.
About Speaker and Mic Placement
Conventional PA systems generally require performers using mics to stand behind speakers to avoid feedback. This makes it difficult to hear the sound from the speakers, making comfortable monitoring impossible. The SA-300s internal anti-feedback system suppresses feedback, allowing performers to monitor the sound in comfort, even when standing in front of the speakers.

Dynamic Function

1 Suppresses feedback that occurs at times when there is no sound from the microphone. For feedback generated when no audio is being input via the microphone (for example, at times when the performer is not at the microphone), the feedback point is automatically detected and the feedback is cut with a dedicated filter.

How to Use Anti-Feedback

Anti-feedback is enabled only for Channels 1 and 2. In addition, the function can be used only when INPUT SELECT is set to MIC.

When Using a Mic Stand

Both the mic characteristics and the characteristics of the surrounding environment can be compensated for. 1. Set up and connect the SA-300 and the mic. Set up the SA-300 and the mic in the positions they will be used. Adjust the height of the mic stand and the angle of the mic. Set the SA-300s VOLUME knob to the level actually to be used in performance. 2. Press the ANTI-FEEDBACK ON/OFF button so its indicator is lit. 3. Hold down the ANTI-FEEDBACK SWEEP button for at least one second. The indicator flashes, and the sound of the calibration signal is output from the speaker. The calibration signal is set automatically in accordance with the mic position and volume setting. * Be aware that the sound output is relatively loud. When measurement and analysis are finished and the feedback prevention processing is completed, the indicator stops flashing and remains lit.
