eA2.fm 4 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Features Thank you for selecting the ZOOM A2 (simply called the "A2" in this manual). The A2 is a sophisticated effect processor for acoustic guitar with the following features. ● Latest technology for top performance Excellent sound quality is assured by signal processing circuitry featuring 96 kHz/24 bit sampling and internal 32-bit processing. Frequency response remains flat to 40 kHz, and signal-to-noise ratio is an amazing 100 dB.
eA2.fm 5 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Terms Used in This Manual This section explains some important terms that are used throughout the A2 documentation. IN MODEL MIC COMP/LIMIT LO EQ ■ Effect module As shown in the illustration above, the A2 can be thought of as a combination of several single effects. Each of these is referred to as an effect module.
eA2.fm 6 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Controls and Functions / Connections Top Panel Module selector Switches between play / manual mode and edit mode. In edit mode, the knob selects the module for operation. BANK [-]/[+] keys In play / manual mode, the keys serve for directly switching to the next lower or higher bank. In edit mode, the keys switch the effect type for the currently selected module. [STORE] key Serves for storing edited patches in memory.
eA2.fm 7 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Controls and Functions / Connections Parameter knobs 1 - 3 These knobs allow changing the value of effect parameters or the level of the overall patch. During rhythm playback, the knobs let you select a pattern, set the tempo, and adjust the rhythm volume. RHYTHM [R/P] key Serves to start/stop rhythm playback. [MANUAL] key Switches between play mode and manual mode. The key is lit when the A2 is in manual mode.
eA2.fm 8 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Selecting a Patch While playing your instrument, try out various patches to see what the A2 can do. Turn power on Use a shielded cable with mono phone plug to connect your guitar to the [INPUT] jack of the A2. To power the A2 from the AC adapter, plug the adapter into a wall outlet and plug the cable from the adapter into the [DC IN] jack on the A2. Set the [POWER] switch on the rear panel of the A2 to ON.
eA2.fm 9 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Selecting a Patch Adjust tone and volume To adjust the effect sound and volume levels in play mode, the Parameter knobs 1 – 3 can be used. Each knob controls a specific parameter. Parameter knob 1 Mainly adjusts the MIX parameter of the MOD/EFX module (the level of the effect sound mixed to the orignal sound). Parameter knob 3 Adjusts the PATCH LEVEL parameter (output level of the entire patch).
eA2.fm 10 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Using the Tuner The A2 incorporates an auto-chromatic tuner. To use the tuner function, the built-in effects must be bypassed (temporarily turned off) or muted (original sound and effect sound turned off). Switch to bypass or mute Setting the A2 to the bypass condition In play mode (or manual mode), press both [W]/[Q] foot switches together briefly and release.
eA2.fm 11 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Using the Tuner Adjusting the reference pitch of the tuner If required, you can fine-adjust the reference pitch of the A2 tuner. The default setting after power-on is center A = 440 Hz. Turn parameter knob 1. 40 The current reference pitch is shown. The adjustment range is 35 – 45 (center A = 435 to 445 Hz). While the reference pitch value is shown, turn parameter knob 1 to adjust it.
eA2.fm 12 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Using the Rhythm Function The A2 has a built-in rhythm function that plays realistic drum sounds in various patterns. The rhythm function is available in play mode or in the bypass/mute condition. Set the A2 to play mode (or manual mode) If the Module selector is set to a position other than "PLAY", set it to "PLAY". HINT The rhythm function can be used both in play mode and manual mode.
eA2.fm 13 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Using the Rhythm Function Adjust the rhythm volume To adjust the rhythm volume, turn parameter knob 3. When you turn the parameter knob, the current setting (0 – 30) is shown on the display. 25 Adjust the tempo The rhythm pattern tempo can be adjusted in the range of 40 – 250 BPM (beats per minute). To continuously change the rhythm tempo, turn parameter knob 2.
eA2.fm 14 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Editing a Patch The patches of the A2 can be freely edited by changing the effect parameter settings. Try editing the currently selected patch to create your own sound. Select the effect module Turn the Module selector to select the effect module to edit. The following settings are available.
eA2.fm 15 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Editing a Patch Terminate the edit mode To terminate the edit mode and return to the play mode, set the Module selector to the "PLAY" position. A2 returns to play mode (or manual mode). NOTE When you select another patch after editing, the changes you have made in edit mode will be lost unless you store the patch first. To retain the changes, store the patch as described on page 16.
eA2.fm 16 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Storing/Copying Patches An edited patch can be stored in a bank of the user area (A - d). It is also possible to store an existing patch in another location to create a copy. In play mode, manual mode, or edit mode, press the [STORE] key. The bank and patch number are shown on the display as a flashing indication. A0 NOTE Patches of banks in the preset area (0 – 3) are read-only. No patches can be stored or copied into these locations.
eA2.fm 17 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Storing/Copying Patches To cancel the store process To cancel the store process, operate the Module selector before pressing the [STORE] key again (step ). Press the [STORE] key once more When the store/copy process is completed, the unit returns to the previous mode, with the target patch being selected. D4 Specify the store/copy target patch number To specify the store/copy target patch number, use the [W]/[Q] foot switches.
eA2.fm 18 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Using the Feedback Control The feedback control function of the A2 allows automatic or manual detection of the frequency range where acoustic feedback occurs. This frequency range is then attenuated to eliminate feedback. Manual operation of feedback control yields best reduction of acoustic feedback (howling). 30 This section describes how to detect the feedback frequency manually. 1. Set the Module selector to "GLOBAL".
eA2.fm 19 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Using the Feedback Control Automatic detection of feedback frequency The A2 can automatically detect the frequency range where acoustic feedback is occurring. If acoustic feedback should suddenly occur during a performance, you can simply hit the foot switch to turn the function on and suppress the feedback sound. This is possible both in play mode and manual mode. 1.
eA2.fm 20 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Using Manual Mode The condition where the foot switches are used to switch the MOD/EFX module or the feedback control function on and off during play is called "manual mode". 1. In play mode, select a patch. When you enter manual mode, the [W]/[Q] foot switches are assigned different functions and cannot be used to select patches. Therefore you should select the patch to use before entering manual mode. 2. Press the [MANUAL] key.
eA2.fm 21 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Using an Optional Foot Switch or Pedal The A2 is equipped with a [CONTROL IN] jack designed for connection of an optional foot switch or expression pedal. This section explains how to use these accessories. Using the foot switch (FS01) Connecting the optional foot switch FS01 to the [CONTROL IN] jack allows functions such as switching banks, performing tap tempo input, and switching the feedback control function on and off. 1. 2.
eA2.fm 22 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Using an Optional Foot Switch or Pedal will activate hold, causing the current delay sound to be repeated (see illustration below). Pressing the foot switch once more cancels the hold condition, and the delay sound will decay normally. ● dM (delay input mute) The foot switch controls input mute on/off for the DELAY module.

For details, see pages 27 – 34. • The way in which the expression pedal changes the parameter can be selected from four patterns (→ p. 33). 5.
eA2.fm 24 ページ ２００５年１０月１４日 金曜日 午後５時２９分 Restoring Factory Defaults In the factory default condition, the patches of the user area (A0 - d9) contain the same settings as the patches of the preset area (00 - 39). Even after overwriting the user patches, their original content can be restored in a single operation ("All Initialize" function). 1. Turn the A2 on while holding down the [STORE] key. The indication "AL" appears on the display. AL 2.
