2.1.3 Power
IEC Power Connection: Your Temblor T10 accepts a standard IEC power cord.
Warning: Do not remove the center grounding prong or use a separate ground-lift
adapter, as this could result in electric shock.
Power Switch: This is the On/Off switch. The power status is indicated by the
illuminated logo on the front of the cabinet.
AC Select Switch: The input-power voltage is set at the factory to correspond with
the country to which it was shipped. Use this switch only if you are using your
Temblor T10 in a country that uses a different standard voltage than is used in the
country where you purchased your T10.
2.1.4 User Controls
Sub Bypass: Connect the bypass footswitch cable to this ¼” input. Stepping on the
footswitch will bypass the subwoofer, highpass filter, and Sub Out altogether. This
will allow the signal from your audio source to pass directly through your Temblor
T10 to your full-range studio monitors and allow you to compare your mix without
subharmonic frequencies. While bypass is active, the LED on the front of your T10 will
flash between red and blue. The footswitch is latching, so the bypass remains in
effect until you step on it again.
Power User Tip: The T10’s Sub Bypass function is a convenient way to make sure your
mix will sound good on systems with and without a subwoofer. Bypassing the subwoofer
will let you hear how the mix sounds without it. After all, many listeners will be using two
speakers without a sub, and you want your mix to sound just as good in a stereo system!
Polarity: The Polarity button reverses the polarity of the summed input signal.
High Pass Filter: Removes frequency content below 80 Hz from the full-range signal
sent from the T10 outputs. This is useful if your main studio monitors do not have
their own highpass filter. The highpass filter is also bypassed when the Sub Bypass is
enabled.
Power User Tip: Leaving frequency content below 80 Hz in full-range studio
monitors can introduce destructive cancellations with the highest frequencies
that are reproduced by the Temblor T10. Conversely, this can reinforce these
frequencies and make your mix seem to have more bass in it than it actually
does. By rolling off your full-range speakers, you will create a more linear
frequency response between the subwoofer and full-range content.
Low Pass Filter: This control determines the upper end of the frequency range
reproduced by the Temblor T10. If you have enabled the onboard highpass filter, set
the Low Pass Filter control to the same value. Otherwise, set the Low Pass Filter
control to the lowest frequency that your main studio monitors can reliably
reproduce. Note that this control only affects the signal going to the internal
amplifier and the Sub Out output and does not affect the main outputs. If you
daisy-chain two T10s, set the second one’s lowpass filter to its highest setting, 130 Hz,
to make sure it reproduces everything it gets from the first T10.
