USER MANUAL Excursion Mini EXM70 YORKVILLE

SERVICE MANUAL EXM70 SMT Disclaimer Due to the complex nature of the use of SMT installed components in Yorkville equipment, we highly caution all service technicians in attempting to repair or replace SMT factory installed components. Many of these components may be glued prior to initial soldering. Replacing SMT components requires expensive specialized de-soldering equipment and training. Yorkville Sound will repair and replace defective SMT components to ensure proper quality assurance and installation is maintained. U.S.A.

Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prongs are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. 10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. 11. Only use attachments/accessories specified by the manufacturer. 12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. 13. Unplug this apparatus during lightning storms or when unused for long periods of time. 14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. WARNING:

• To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture and objects filled with liquids, such as vases, should not be placed on this apparatus.
• To completely disconnect this apparatus from the ac mains, disconnect the power supply cord plug from the ac receptacle.
• The mains plug of the power supply cord or appliance coupler shall remain readily accessible.

The combi-jack is for a mic (XLR) or a balanced line level (1/4-inch) source. 24V phantom power is present on the XLR portion of the jack.

The combi-jack is for a mic (XLR) or an instrument (1/4-inch). 24V phantom power is present on the XLR portion of the jack.

The XLR jack is for a mic, the 1/8-inch phone jack for media players and the Bluetooth™ for streaming audio. 24V phantom power is present on the XLR input of the jack. Note: When Bluetooth™ is used the volume is controlled by Channel 3’s Level control.

Bluetooth™ operating range is rated 10 meters (33 feet). The quality of the link can be affected by an excess of trafc in the 2.4 GHz bandwidth or obstructions.PairingFor ‘Pairing’ depress the Enable Button for 4 seconds and then release.StatusSlow blinking indicates pairing mode while fast blinking indicates an available, unpaired connection. A steady (solid) blue light indicates it’s paired and audio is available to Channel 3.

5. Channel Level Controls

The Level controls adjust the channel gain over an 85 dB range. Use these controls to adjust each channel’s volume in the overall system mix. The LED indicates clipping.

6. Channel Shape Controls

Setting this control towards ‘Music’ shapes the response to be suited for reproducing prerecorded music while setting the control towards ‘Speech’ accentuates the mid-frequencies which help speech and vocals. The response is at in the center position.

7. Channel Effects Controls

This control determines how much of the selected effect is applied to the corresponding channel.

The Master Control is used to set the overall level of the Yorkville EXM70.

Three effects are available with this control, as well as an off (no-effects) position. The effects are Delay, Hall Reverb and Room Reverb. The selected effect is available to all 3 input channels and the amount of effect applied is controlled by the individual channel’s effects knob.

The Link jacks are used to connect multiple EXM70 systems and/or a subwoofer. The jacks are in parallel, both a male and female XLR to help make it more convenient to ‘link’ enclosures together. To use the Link feature, insert a standard XLR patch cable between cabinets.

The built in pole stand adapter and can use a standard Yorkville pole-mount speaker stand. Printed In CANADA QuickStart-EXM70-00-1v7 • YS#QSTARTEXM70 • December 15, 2022
