In case this equipment has to subject to FCC/IC SAR (Specific Absorption Rate) exposure test, this equipment is designed to meet the requirements for exposure to radio waves established by the FCC and ISED. These requirements set a SAR limit of 1.6 W/kg averaged over one gram of tissue. The highest SAR value reported under this standard during product certification for use when properly worn on the body or on the head, with no separation . 20) Rated operating temperature: 0 °C-40 °C. 18) Tout changement ou modification non expressément approuvé par la partie responsable de la conformité pourrait annuler le droit de l’utilisateur à utiliser l’équipement. 19) Cet équipement est conforme aux limites d’exposition aux rayonnements FCC et ISED établies pour un environnement non contrôlé sans restriction. Dans le cas où cet équipement doit être soumis au test d’exposition FCC/IC SAR (Specific Absorption Rate), cet équipement est conçu pour répondre aux exigences d’exposition aux ondes radio établies par la FCC et ISED. Ces exigences fixent une limite DAS de 1,6 W/kg en moyenne sur un gramme de tissu. La valeur DAS la plus élevée signalée dans le cadre de cette norme lors de la certification du produit pour une utilisation lorsqu’il est correctement porté sur le corps ou sur la tête, sans séparation. 18) 任何未经合规负责方明确批准的变更或修改,都可能使用户失去操 作设备的权限。 19) 针对不受控制的无限制环境, FCC和ISED规定了辐射暴露限值，该 设备符合这一限值。如果该设备必须接受FCC/IC SAR（比吸收率） 暴露测试，则该设备的设计应满足FCC和ISED制定的无线电波暴露 要求。这些要求设定了一克人体组织平均1.6 W/kg的SAR限值。在 产品认证时，当正确佩戴在身体或头部上，且无分离的状态下，会 根据本标准给出最高SAR值。 20) 额定工作温度：0°C~40°C。 21) 消费者若使用电源适配器供电，则应购买配套使用获得CCC认证并 满足标准要求的电源适配器。

OWNER’S MANUAL ENGLISH This manual is a guide to the features and functions of Mustang Micro Plus—a plug-and-play headphone amplifier and interface that connects directly to your guitar and bass to deliver amp models, effects models, Bluetooth stream- ing and more. With fantastic Fender Mustang amplifier sound and yet no larger than a deck of cards, Mustang Micro Plus is easily portable and provides up to six hours of battery-operated playing time. Mustang Micro Plus is simple and intuitive. Connect it to any popular instrument model using the 1/4” rotating input plug. With 25 great-sounding Mustang amplifier models, 25 effect models in moveable blocks and remote editing using the Fender TONE™ app, players can choose among 100 onboard presets (70 factory presets and 30 empty pre- sets ready for personalized customization) and access cloud presets. Turn Bluetooth on and stream music to play along with, or play to online sources with synced audio and video. The display window conveniently shows the preset in use, onboard tuner and other functions, and the USB-C port enables easy audio recording and firmware updates. With re- markably compact sound, style and versatility, Mustang Micro Plus delivers it all straight to your earbuds, headphones or digital recording software. INTRODUCTION 1 FEATURES A. DISPLAY WINDOW: Black display window with white text shows preset name and number in use. Also displays EQ, MODIFY, SAVE and TUNER functions. To conserve battery life, the display will time out 10 seconds after the last button press; press any button to wake the display. B. MASTER VOLUME: Adjusts overall volume level of instrument signal and Bluetooth audio. C. ROTATING INPUT PLUG: Standard mono 1/4” plug rotates up to 270 degrees for easy compatibility with all popular instrument models. D. TAP TEMPO/TUNER BUTTON: Tap button twice or more to set tempos for delay effects; press and hold for two seconds to activate onboard tuner. E. MODIFY BUTTONS: Buttons (-/+) adjust a single parameter of assigned modulation, reverb or delay effect; display indicates parameter control. F. EQ BUTTONS: Buttons (-/+) adjust overall instrument signal tone. Select among nine EQ presets including flat (post amp/effect); display indicates EQ preset in use. G. PRESET BUTTONS: Buttons (-/+) select preset from 100 options; display indicates preset in use. H. SAVE: Press to initiate preset save prompt on the display. I. POWER/BLUETOOTH SWITCH/LED: Three-position slider switch turns Mustang Micro Plus on and off and activates Bluetooth audio pairing. LED indicates power/Bluetooth/charging status. J. USB-C PORT: For charging, recording output and firmware updates. K. HEADPHONE OUTPUT: 1/8” stereo headphone jack. 2 Connecting Mustang Micro Plus to your guitar couldn’t be easier—simply rotate the 1/4” input plug out from the unit and plug it into the guitar’s input jack. Slide the power switch to the center ON position; the power LED will illuminate green for 10 seconds and then extinguish, indicating that Mustang Micro Plus is on and charged (differ- ent LED colors indicate different charging status; see page 8). You’re now ready to choose or create a preset with an amp model and a selection of effects, adjust volume and EQ, tune up, engage Bluetooth, and start playing. If power is on but no instrument input is detected for 15 minutes, Mustang Micro Plus will automatically switch to a low-power sleep mode; press any button to wake it up. Slide the power switch to OFF to power down. INSTRUMENT CONNECTION AND POWERING UP WARNING: Connecting Mustang Micro Plus to your instrument, disconnecting it or touching the end of the device’s plug may cause a loud noise. To avoid hearing damage when wearing heaphones/earbuds, follow these steps to ensure safe operation of your device: • When connecting/disconnecting Mustang Micro Plus, remove headphones/earbuds, ensure that the device is turned off, or ensure that the device’s MASTER VOLUME control is set to zero. • Turn the device on with MASTER VOLUME set to zero, then gradually adjust volume to reach a comfortable listening level. When wearing headphones/earbuds, connecting/disconnecting Mustang Micro Plus or touching its exposed plug while unit is on and MASTER VOLUME is up is similar to plugging an instrument cable into a live amplifier with volume up or to touching the exposed end of a live instrument cable. 3 4 All Mustang Micro Plus presets contain five “blocks” for creating an entire signal path from input to output—one amplifier block and four effects blocks. There are 25 amplifier models, each paired with a default cabinet model, and 25 onboard effect models organized into four categories: stompbox (11), modulation (6), delay (4) and reverb (4). The amp block contains an amplifier model paired with a fixed speaker cabinet model. Basic amp settings can be adjust- ed, while more advanced settings such as noise gate, gate position, sag, tube bias, etc. are fixed. The amp block is station- ary, with its default position at the center of the signal path. Each preset has four effect blocks, one for each effect category—stompbox, modulation, delay and reverb. Effect blocks are moveable and can be placed before or after the amp block using the Fender TONE app. BLOCKS AMPLIFIER AND CABINET MODELS AMPLIFIER MODELCABINET MODELAMPLIFIER MODELCABINET MODEL ’57 Champ’57 ChampBB15 Low Gain1x12 BB15 ’57 Deluxe’57 DLTXBB15 Mid Gain4x12 SOL ’57 Twin’65 TwinBB15 High Gain4x12 SOL ’59 Bassman’59 BassmanSuper-Sonic1x12 SS ’65 Princeton’65 PrincetonFBE-1004x12B V30 ’65 Deluxe’65 DLTXMetal 20004x12 GB ’65 Twin’65 TwinUber4x12 RCT ’60s British2x12 Blue’60s Thrift’57 DLX British Watts4x12 V30ExcelsiorExcelsior ’70s British4x12 GBStudio Preamp(None) ’80s British4x12 75WTube Preamp(None) ’90s American4x12 GBAcoustic Sim(None) British Colour4x12 75W EFFECTS MODELS STOMPBOXMODULATIONDELAY 1 Overdrive 12 Sine Chorus 18 Mono Delay 2 Greenbox 13 Triangle Flanger 19 Tape Delay 3 Mythic Drive 14 Phaser 20 2290 …
