3 Dear customer, tank you for purcasing Evo SUPPLY. Wat you ave is a first-rate dedicated power supply wit many unique features conceived to obtain te best audio performance out of te iface Evo and oter 9V-operated products. Evo SUPPLY features a Li-Ion battery wit capacity sufficient to many ours of continuous listening wit te iface Evo, an integrated battery carger and a low noise regulator wic is used to give power to te outputs wile te battery is being carged. Tis allows for uninterrupted operation anc certain full carge time. Evo SUPPLY as two outputs to power two 9V devices, like te iface Evo and te Evo CLOCK. Tey can be switced off wen te powered devices are not used to save battery carge. An external universal voltage wall adaptor is provided for battery carging and supply of te devices wile te battery is being carged. Te adaptor may be disconnected wen using te battery to minimize te interferences from te mains. We feel tat your expectations will be fulfilled by Evo SUPPLY: you ll ear your music files in a way like never before, prepare for a wole new experience! Nadia Marino, CEO Please annotate ere your Evo SUPPLY serial number for future reference: S/N: Date of purcase: 3 Copyrigt 2012, Srl

5 1. Unpacking Te Evo SUPPLY box contains te following items: Evo Supply 1 supply cable terminated wit 5.5/2.1mm plug on one end and wit Bulgin eavy duty plug on te oter end 15V/2A wall adaptor or 15V/2A adaptor wit detacable power cord Sould any item be missing, please contact your dealer for a warranty claim. Please note te supply cable may be obtained as a separate item if needed. 5 Copyrigt 2012, Srl

6 2. Front Panel 1) Supply input. Apply 15V DC from te wall adaptor provided in te package. Anoter power supply may be used if necessary, but user must be aware tat in tis case te warranty is void. Tip is positive, ring is negative. A maximum current of 2A is necessary. Tis input is protected against polarity inversion. 2) Carge mode switc. Allows for selection of two operation modes for te battery carger included. Select BATTERY to use te battery carge up to te complete depletion. Te outputs will be automatically switced off wen te low voltage tresold is reaced, to avoid an excessive depletion wic would damage te battery. Selecting tis mode will avoid using te internal low-noise regulator to power te devices for best performance, but operation will not be uninterrupted. Select CHG/REG to ensure uninterrupted operation. Te battery will be used as primary power source up to complete depletion. Wen reacing te low voltage tresold, te battery carger will automatically enabled, te battery will be disconnected from te load and te low noise regulator will provide power to te devices. Te switcover is transparent to te user. At te end of te carge process, te outputs will revert to te battery. Te low noise regulator as been designed to ensure very low noise, so te user sould ear very little differences between te battery and te regulator. 3) Outputs. Connect te supply cables provided in te package. Positive is te upper ole, negative is te lower ole. 4) Output switc. Switces outputs on and off. It is advisable to switc outputs off wen te devices attaced to te Evo SUPPLY are not in use, to avoid carge cycles wic sorten te battery life. 5) Power indicator. Turns on wen te wall adaptor is connected to te Evo SUPPLY and to a mains socket. 6) Carge indicator. Turns on wen carge is in progress. 6 Copyrigt 2012, Srl

7 3. Connections Connect te plug of te wall adaptor to te supply connector (Page 6, no.1) of Evo SUPPLY. Connect te Bulgin plug of eac supply cable to one of te Evo SUPPLY output connectors (Page 6, no.3). Connect te 5.5/2.1mm plug of eac supply cable to a 9V-operated device. Of course, one cable may be used wen one device only needs supply; te oter output will be unused. 7 Copyrigt 2012, Srl

8 4. Operation modes 4.1. Carge Inibit Tis operation mode is selected wen te carge mode switc (Page 6, no.2) is set on BATTERY. Tis mode allows for operation from battery only, even wit te wall adaptor disconnected, to ensure te least disturbance form te mains. In tis operation mode, te battery carge is inibited and te attaced devices are powered by te battery until te voltage goes down to te low voltage tresold. At tat point, te Evo SUPPLY battery protection circuit for depletion engages and te battery is isolated from te load to prevent furter depletion. To restore te operation and start te carge, it is necessary to switc to automatic carge start mode and to connect te wall adaptors if it s been previously disconnected Automatic Carge Start Tis operation mode is selected wen te carge mode switc (Page 6, no.2) is set on CHG/REG. Wen tis mode is selected, te battery remains te main power source, tat is, it is used to power te attaced devices. Wen te low voltage tresold is reaced, owever, te battery carge is automatically engaged, te battery is disconnected from te outputs and a low noise regulator is connected in its place to ensure continuity of te output supply. Tanks to a reservoir capacitor, te switcover is transparent to te devices. Carge lasts around tree ours, during wic te output current is provided by te 9V internal low noise regulator. Tis allows for uninterrupted operation of te attaced devices, wit a sligt supply quality reduction. Te carge-in-progress is indicated by te carge indicator LED (Page 6, no.6). At te end of te carge time, te outputs automatically revert to te battery. Te automatic carge start mode must be selected to manually enable te battery carge after te unit as automatically switced outputs off following to battery depletion in carge inibit mode. 8 Copyrigt 2012, Srl

9 5. Notes on Battery Usage Te Evo SUPPLY includes a Litium-Ion battery. It s a ig performance battery wit ig power density and low internal resistance, capable of very ig surge currents and very clean supply. Te battery as a built-in protection circuit tat protects it from overcurrent and sort circuits, overcarge and excessive depletion. Te protection circuit sould be sufficient to protect te battery against wrong operation or usage. Moreover, te Evo SUPPLY circuit also includes a depletion protection circuit wic engages at a voltage sligtly iger tan te low voltage tresold as set in te built-in protection circuit. Tis allows for battery s long life. Despite te aforementioned protection circuits, a Li-Ion battery is a delicate device wic needs to be properly used to avoid damages. Particularly, do not expose te Evo SUPPLY to excessive eat or cold or fire, nor drop liquids on it. Do not sort-circuit te outputs. Sould te Evo SUPPLY be exposed to temperature beyond te allowed range, put te unit in a normal environment and allow for at least one our before operating it. Too cold or too ot a battery would result in an explosion wen operated. Please refer to te specifications section (Page 10) for temperature limits. 9 Copyrigt 2012, Srl
