How to connect and congure a Surround Speaker Setup
When using Ensemble with a surround speaker setup, the rst set of outputs can be congured as speaker
outputs suitable for connection to a 5.1, 7.1, or 9.1 speaker system. With this conguration, turning the Output
Controller knob will adjust volume of all applicable outputs simultaneously� Here’s an example for a 5�1 speaker
setup:
• Monitor L: Front Left
• Monitor R: Front Right
• Output 3: Center
• Output 4: Sub-woofer
• Output 5: Left Surround
• Output 6: Right Surround
Note: To access outputs 3-6, you will need a breakout cable that converts the DB25 connector to 8 XLR male
plugs.
3� From the Main Output Format drop-down box, select 5�1 (Out 1-6)�
Now when you adjust the Ensemble’s output volume, it will aect outputs 1-6
simultaneously�
Adjust for Volume Dierences Between Speakers
There may be cases where the perceived volume of one, two, or three speaker sets, or a speaker in a
surround setup, is slightly dierent from the others. The output Trim controls in Apogee Control can be used to
compensate for this so all speakers produce the same perceived volume levels�
1� Open Apogee Control and click the Out tab at the top of the Primary Window�
Between Analog Level and Source settings are your trim controls�
2� Click then drag up or down on the trim control to adjust the value�
• Alternatively, you can double-click the number in the middle and
manually enter in a value�
Note: Trims only allow a reduction in signal level. Lower the trim of the speaker or speaker set that is too loud.
If a speaker or speaker set is too quiet, then leave the trims of those speakers at maximum (zero) and lower the
trim of all the other speakers.
1� Connect your speakers to Ensemble’s analog
outputs 1-6�
2� Open Apogee Control and click the
Device button to reveal the Device
