S-6/A·B­S-7/A·B and R-6/A·B­R-7/A·B Terminals (Stereo) Connect stereo type effects units to these terminals. By using only the A side, these terminals can also be used as usual monaural effect loops.
NOTE Turning on/off of the stereo effect loop is done at the return side. Since the stereo effect loops continue sending the send side signals, you can output delay effects instantly when for example a delay effect unit is connected to one of them.

IN-8, S-8 (N.C), R-8, & OUT-8 (N.O) Terminals (Separate Loop) In addition to the usage as an effect loop, the S-8 (N.C) terminal can be used as a control terminal (normally closed) for amplifier channel switching, etc. When Loop 8 is turned off, the tip and ground of the jack are electorically connected. The OUT-8 (N.O) terminal can be used as a control terminal (normally open): When Loop 8 is turned on, the tip and ground of the jack are electrically connected.
BOOST-A Knob: This knob adjusts the output level at the OUT-A terminal when the Boost function is activated. To set to unity gain, turn it fully counterclockwise. The adjustable range is up to about +14 dB. When the STEREO/PARA switch is set to PARA mode, the output signal level of the OUT-B terminal is adjusted to the same output level as that of the OUT-A terminal.
BOOST-B Knob: This knob adjusts the output level at the OUT-B terminal when the Boost function is activated and the STEREO/PARA switch is set to STEREO mode. To set to unity gain, turn it fully counterclockwise. The adjustable range is up to about +14 dB. When the STEREO/PARA switch is set to PARA mode, signals are output from the OUT-B terminal at the output level adjusted by the BOOST-A knob.

Signal Flow
STEREO Mode In this mode, L6 and L7 are used as stereo loops. Signals from the A side loop are fed from the OUT-A terminal and signals from the B side loop are fed from the OUT-B terminal. N.B. When the loop of L6 and L7 is turned off, signals same as at the OUT-A terminal are output from the OUT-B terminal, simarly to PARA mode.

PARA Mode In this mode, L6 and L7 are used as monaural loops. Signals are fed from the OUT-A and OUT-B terminals in parallel. N.B. When in PARA mode, the send/return terminal of L6 and L7 uses the A side.

How to Store/Recall Effect Loop Combinations or Various Functions (Preset Mode)
Preset mode is a mode in which effect loop combinations, settings for MIDI and control signal transmission, etc. can be stored in the ARC-4 and the contens of the memory can be recalled by pressing the PS/L switch. In contrast with Preset mode, a mode in which a footswitch can be used to turn on/off each effect loop is called “Direct mode.”

Organization of Presets

What we call a “Preset” is a compilation of effect loop combinations and various control signals settings, etc. The ARC-4 can handle 10 presets as a collection (Bank) and can store 2,000 presets (10 presets x 200 banks).

Bank

Preset-6 Preset-7 Preset-8 Preset-9 Preset-10

Preset Number

NOTE PS8­PS10 (Preset No.8 to Preset No.10) cannot be recalled from the ARC-4 main unit. By connecting the EXTERNAL FOOTSWITCH/EFS-3 (option) to the OPTION-1 (EFS-3) terminal, it becomes possible to recall presets externally.

Managing Presets
In Preset mode the ARC-4 can manage presets in two ways.
Bank Mode Presets (10 presets) are managed in the order of bank numbers (001­200).
Setlist Mode This mode is used to manage banks in a sequence in your desired order. For example, the combinations of effects units to be used in a song are compiled in a bank. Then by serializing these banks in accordance to the order in which songs are played in live performance (setlist), presets can be managed on a song-basis. This ARC-4’s feature is very useful for live performances.
Switching between Preset and Direct Modes
1. Press the MODE switch. Each press alternates Preset and Direct modes. In Preset mode the blue PS LED illuminates and the Display-2 shows the bank number or bank title. In Direct mode the red DIR LED illuminates and the Display-2 shows DIRECT ACCESS.
NOTE In Preset mode, effect loop’s on/off settigs, settings for control and MIDI signal transmission, etc. are stored in a preset and the memory contents are recalled by pressing the corresponding PS/L switch. In Direct mode pressing a PS/L switch can turn on/off the corresponding loop directly.

Storing Phase Invert Function (INVERT) Setting in a Preset
1. Press the MODE switch to select Preset mode. 2. Use the BANK /L8 or BANK /STORE switch to select the desired bank. 3. Use the PS/L switch to select the preset to which you want to store the
setting. 4. Press the SELECT switch to select “FUNC” and to turn on the LED. 5. Press the ON/OFF 5 switch to activate the Phase Invert function (INVERT). 6. Press the STORE switch to store the setting.
NOTE Some effects units invert (reverse) the phase causing their sound to be buried in band mix. In such a case turn on this INVERT function to correct the phase of the signal (to be in phase) before outputting. However intentionally inverting the phase can sometimes enhance the sound. So please try this function in various situations. Signal phase can be confirmed with the PHASE ANALYZER/PHA-1 (option).
Storing Boost Function Setting in a Preset
1. Press the MODE switch to select Preset mode. 2. Use the BANK /L8 or BANK /STORE switch to select the desired bank. 3. Use the PS/L switch to select the desired preset. 4. Press the SELECT switch to select “FUNC” and to turn on the LED. 5. Press the ON/OFF 6 switch to activate the Boost function. 6. Press the STORE switch to store the setting.
NOTE The boost amount of the signals at the OUT-A and OUT-B terminals can be adjusted respectively by the BOOST-A and BOOST-B knobs on the rear panel.

Storing an Effect Loop Combination
1. Press the MODE switch to select Preset mode. 2. Use the BANK /L8 or BANK /STORE switch to select the desired bank. 3. Use the PS/L switch to select the preset to which you want to store the
combination. 4. Press the SELECT switch to select “LOOP.” 5. Press the ON/OFF 1­8 switch to select the effect loop you want to store. 6. Press the STORE switch to store your selection.
NOTE Effect loop combinations can be stored even in Direct mode. Select the preset by following the above steps 1­3 and press the MODE switch to change to Direct mode. Then press the PS/L switch to select the loop you want to store and press the STORE switch or BANK /STORE switch to store it.

Storing Mute (MUTE-A, MUTE-B) Setting in a Preset

Press the SELECT switch to select “FUNC” and to turn on the LED. 5. Press the ON/OFF 7 or 8 switch to select the output terminal you want to
mute. 6. Press the STORE switch to store the setting.

Recalling a Preset
