AUDIO CONNECTIONS

NOTE: Before making audio connections, ensure the VOLUME control on each 3 Series speaker/subwoofer is set to the full counter-clockwise (minimum) position.

The 3 Series speakers are equipped with balanced XLR and 6mm (1⁄4") TRS inputs for connection to professional computer audio interfaces, mixing consoles, and audio production equipment, as well as unbalanced consumer audio products such as personal music players, consumer audio receivers, and audio visual equipment.

Connect professional equipment with balanced outputs to the XLR or 6mm (1⁄4") TRS input of the speaker using balanced audio cables.

3 Series speakers are equipped with an INPUT SENSITIVITY switch, which is set to the -10dBV setting at the factory. This setting will be best for many applications. However, you should set the switch to the +4dBu setting under the following conditions:

  • When connecting 3 Series speakers to professional equipment with +4dBu nominal output level. To determine the nominal output level of the connected equipment, consult the documentation supplied with the connected equipment.
  • The sound is distorted, even when the speaker VOLUME controls are set to minimum settings

NOTE: When using the LSR310S in a system with 3 Series MkII Studio Monitors, set the INPUT SENSITIVITY switch on the 305P, 306P, or 308P MkII speakers to the -10dBV setting regardless of the LSR310S INPUT SENSITIVITY switch setting.

MAKING SOUND

  • Ensure the VOLUME control on each 3 Series speaker/subwoofer is set to the full counter-clockwise (minimum) position.
  • Power on the connected audio equipment (mixing console, computer audio interface, preamp, etc.).
  • Set the POWER switch on each 3 Series speaker/subwoofer to the ON position. After a short delay, the POWER LED on the front of each speaker will illuminate and the speakers will be ready to reproduce audio signals.
  • Play full range program material from the source with ample low frequency content so that you can properly judge the bass response of the system. Now slowly advance the volume control of the source device until its nominal operating level is achieved.
  • Slowly increase the VOLUME control on each 3 Series Studio Monitor until the desired listening level is achieved and all speakers are matched in output level to achieve a balanced image.
  • Balance the subwoofer in the system using the rear panel VOLUME control. Additional balance of bass can be achieved by changing the placement of the subwoofer in the room.

Use the following procedure to disable the auto-low power standby mode:

  • Power speaker OFF.
  • Set BOUNDARY EQ to the “0dB” setting.
  • Set HF Trim to “+2dB” setting.
  • Set the VOLUME control to “1” (full counter-clockwise setting).
  • Power the speaker ON.
  • Within a period of 5 seconds following power-ON: Set BOUNDARY EQ to the “-3dB” setting and... Set the HF TRIM switch to the “-2dB” setting.
  • The front panel LED will flash for 5 seconds indicating the low-power auto-standby mode has been disabled and will remain disabled upon subsequent power cycles.

Use the following procedure to enable the auto-standby mode:

  • Power the speaker OFF.
  • Set BOUNDARY EQ to the “-3dB” setting.
  • Set HF TRIM to the “-2dB” setting.
  • Set the VOLUME control to “1” (full counter-clockwise setting).
  • Power the speaker ON.
  • Within a period of 5 seconds following power-ON: Set the BOUNDARY EQ switch to the “0dB” setting and... Set the HF TRIM switch to the “+2dB” setting.
  • The front panel LED will flash for 5 seconds indicating the low-power auto-standby mode has been enables and will remain enabled upon subsequent power cycles.

AUDIO CONNECTIONS

  • Connect signal sources to either the XLR or 6mm (1⁄4") INPUT connectors. Connect a single signal source to the speaker using either the XLR INPUT connectors, OR the 6mm (1⁄4") TRS INPUT connectors. Do not connect multiple signal sources to the XLR and 6mm (1⁄4") input connectors simultaneously.
  • If the LSR310S subwoofer is being used to reproduce the .1 LFE channel in a surround sound system, connect the .1 LFE signal to either the LEFT or RIGHT input of the subwoofer.

SETTING THE SUBWOOFER LEVEL

  • When the LSR310S subwoofer is used in a system with 3 Series MkII Studio Monitors, the ideal balance is achieved when the position of the subwoofer VOLUME control is set to the same position as the main speaker VOLUME controls. However, note that the placement of the speakers in the room can affect the amount of bass heard at the listening position. If more or less subwoofer volume is desired, use the subwoofer VOLUME control to achieve the optimum balance for the application and your preference.
