What’s in the Box
Hookup
Your Eris Sub 8BT features all the connections and controls needed to use it as the central hub for your monitor system. The onboard high- and lowpass filters let you dial in the correct crossover frequency for your full-range monitors.
Set the Low Pass Filter to 80 Hz and listen to your full system, experimenting with the Low Pass frequency until you system has the most linear response.
Power User Tip : Complete calibration instructions can be found in the
Eris Sub 8BT User Manual on the
PreSonus website at www.PreSonus.com.
CAUTION
WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS
EQUIPMENT TO RAIN OR MOISTURE. DO NOT REMOVE COVER. NO USER SERVICEABLE PARTS
INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL.
POWER
Ac Select
You can pair an additional device, by repeating steps 6-8, and this second pairing will be stored along with the first one.
Note: Audio can only be streamed from one Bluetooth device at a time.
Power User Tip: The next time you switch on your Eris monitors, your
stored devices will automatically be paired when powered up.
Connections and Controls
-
Input Gain. Sets the level of the input signal before it is amplified.
-
Low Pass Filter. Sets the upper end of the frequency range reproduced by the Eris Sub 8BT. If you enabled the onboard High Pass Filter, set this control to 80 Hz. Otherwise, set the Low Pass Filter to the lowest frequency that your main monitors can reliably reproduce.
-
TRS Inputs. Balanced 1/4” TRS line-level inputs.
-
RCA Inputs. Unbalanced RCA line-level inputs.
Note: When both connections are in use, the RCA inputs will sum into the balanced TRS connections. -
Bluetooth Button. Pressing this button starts the pairing process.
-
Standby used to engage/disengage a power save mode that adheres to the EU Energy Efficient Products Directive to conserve energy when not in use.
-
Polarity. Reverse the polarity of the summed input signal. Power User Tip: Once you have connected your Eris Sub 8BT to your system, try experimenting with each setting while listening to your favorite music. Leave this switch in the position where the bass was the loudest.
-
High Pass Filter. Removes frequency content below 80 Hz from the full-range signal sent form the Eris Sub 8BT outputs. This is useful if your main studio monitors do not provide an onboard high pass filter.
-
TRS Outputs. Balanced 1/4” TRS line-level outputs.
-
RCA Outputs. Unbalanced RCA line-level outputs. 11. Power Switch. This is the On/Off switch, the power status is indicated by the illuminated logo on the front of the cabinet.
