System Configurations

The scalable nature of the Yorkville EXM 70/Mobile/Mobile12 allows for several configurations that can be utilized to suit your needs. Here are some examples:

FIG 4 System Configurations.JPG

Channel Inputs

FIG 5 Channel Inputs.JPG

Channel 1
Channel 1 is equipped with a combi-jack optimized for a microphone (XLR) or a balanced line level
(1/4-inch) source. A level control sets the gain and relative volume while the clip LED indicates the onset of clipping distortion. For powering condens-er microphones, 24V of phantom power is present on the XLR input portion of the jack.

Channel 2
Channel 2 is equipped with a combi-jack optimized for a microphone (XLR) or an instrument level source (1/4-inch) source. A level control sets the gain and relative volume while the clip LED indi-cates the onset of clipping distortion. For powering condenser microphones, 24V of phantom power is present on the XLR input portion of the jack.

Channel 3

Channel 3 is equipped with an XLR jack opti-
mized for a microphone (XLR), an unbalanced
TRS 1/8-inch phone jack optimized for portable media players and Bluetooth™. A level control sets the gain and relative volume while the clip LED indicates the onset of clipping distortion. For power-ing condenser microphones, 24V of phantom power is present on the XLR input portion of the jack.

Note: When Bluetooth™ is used the volume is controlled by Channel 3’s Level control.

Bluetooth™
The Yorkville EXM 70/Mobile/Mobile12 is capable of receiving streaming audio over Bluetooth™ from devices such as smart phones, tablets and laptops. Pairing your device with the EXM 70/Mo-bile/Mobile12 is simple and gives you the freedom to play your music wirelessly.

Pairing: When the Pairing Button is depressed for 4 seconds and then released, the Blue-tooth™ audio connection is available for pairing.

Status: The blue status indicator alerts the user to the current status of the Bluetooth™ con-nection. A fast blinking light indicates an available, unpaired connection. A slow blinking blue light is pairing mode waiting to pair, and a steady (solid) blue light is paired and audio is available to Channel 3.

Level Control: The Channel 3 Level control is used to set the audio level for the Bluetooth™ connection. Level may also be controlled directly at your streaming device.
The EXM 70/Mobile/Mobile12’s Bluetooth™ operating range is rated for 10 meters (33 feet) line of sight. The quality of the link can be affected by an excess of traffic in the 2.4 GHz bandwidth or structures between the EXM 70/Mobile/Mobile12 and the streaming device.
Note: When connected with Bluetooth™, ALL audio is streamed from your device. If you don’t want your streaming music to be interrupted, turn off ‘notifications’ on your device.

Channel Controls

Level Control
The EXM 70/Mobile/Mobile12 features active channel input circuitry with exceptionally high audio headroom. The Level control adjusts the channel gain over an 85 dB range. Use this control to ad-just the channel’s level in the overall system mix.

Shape Control
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 flat in the center position.

Effects Control
This control determines how much of the selected effect (see “Effect Selector” in the “Master Sec-tion” portion of this manual) is applied to the corresponding channel.

Master Section

Master Control
The Master Control is used to set the overall level of the Yorkville EXM 70/Mobile/Mobile12.

Note: When two systems are linked together, the Master Control only af-fects the level of the unit on which it is located.

Effects Selector
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.

Note: If effects are not in use, set this switch to the off position to help conserve battery life.

Link Section

In situations where additional bass or input channels are needed, The Link jacks can be used to connect multiple EXM 70/Mobile/Mobile12 systems and/or a subwoofer.
Link Jacks
The Link jacks are in parallel and we have provided both a male and female XLR to help make it more convenient to ‘link’ EXM 70/Mobile/Mobile12 enclosures togeth-er. To use the Link feature, insert a standard XLR patch cable between cabinets.

Battery Status Indicators

The back of the EXM Mobile/Mobile12 has a series of four LEDs (green, green, yellow, and red) to indicate the approximate charge level. The up-per green LED is illuminated if there is greater than 85% charge in the battery. The red LED only will indicate that the battery is critically low
(approximately 10% remaining) and needs immediate charging.

Low-Power “Sleep” State
The EXM Mobile/Mobile12 features a special “sleep” mode which reduces energy consumption when the system is not in use and this also preserves battery life. This mode is automatic and nearly undetectable to users when the EXM Mobile/Mobile12 is configured properly. To ensure the sleep state doesn’t interfere with normal operation, the output level should be controlled with the Master control, especially where quiet playback is desired.

Charging Indicator
Whenever AC is connected to the unit, the charging indicator will be turned on. If it is green, the unit is fully charged. If it is red, the unit is in the process of charging.

Charging the EXM Mobile/Mobile12
To charge the EXM Mobile/Mobile12, plug it into an AC power source using the included power cord. The charging indicator LED is the best indication of the charging status; even if all of the battery status LEDs are lit, there is still possibly some additional charging time required. The EXM Mobile/Mobile12 can be safely left connected to AC power for charging indefinitely. It will intelligently control its own charging regime when plugged in long-term.

The EXM Mobile/Mobile12 will not charge when the temperature is below 0° C or above 45° C.

If the EXM Mobile/Mobile12 is going to be stored unused for a long period of time (greater than 6 months) it is advisable to periodically plug it in to charge up the battery.

If the EXM Mobile/Mobile12 has been stored for a long period of time unused and it has not been maintained, it is advisable to connect the charger and leave it plugged in for approximately 24 hours.

The EXM Mobile Series is delivered with 40-50%of the charge capacity. Please charge your unit for 5-hours prior to initial battery operation!
