1. TRS Input – This ¼” input accepts
balanced “TRS” or unbalanced “TS”
cables from your mixer, computer, or
any other line level source. Both types
of cabling will work, but we
recommend balanced TRS (or XLR)
cables since they give you better
performance and lower noise
(especially if you’re using longer
cables).
2. XLR Input – This jack functions
exactly the same way as the TRS input
(see above), but it uses balanced XLR
cabling.
3. Gain – This knob sets the input
gain of the speaker. Use this knob to
set a comfortable loudness level for
monitoring.
4. Rear Port – The rear port
augments the bass generated by the
woofer to increase the low frequency
SPL over that of non-ported speakers.
Make sure this hole is not obstructed
since this will adversely affect bass response.
5. Acoustic Space Switch – This switch
compensates for placement near walls and corners.
Please see section titled “About the Acoustic Space
Switch” for more on these settings.
6. Hi Boost – This switch allows you to tailor the
speaker’s high frequency response to your control
room. Please see the section “About the Hi-Boost
Switch” for more about these settings.
7. Mid Boost – This 2-position switch provides a 2.5 dB wide-band boost in the
midrange at 1.8kHz. This has the effect of moving the soundstage “forward”
closer to the mix position. Some engineers prefer to have this boost if the
speakers are positioned farther than a few feet away. We recommend you try
either the boosted “+” or bypassed “0” settings for a few mixes and select
whichever one makes your mixes translate better.
Both XLR and TRS
connectors have been
provided for your
convenience, but please use
only one connection at a time
to avoid overloading the
inputs.
