A) SELECTION OF THE SOURCE : check in « SOURCE » that the
inputs and outputs being listed are the ones being used:

■

RCA+HL : RCA INPUTS and/or HI-LEVEL INPUTS/OUTPUTS

■

XLR : XLR BALANCED INPUTS2)

B) INPUT CHANNEL SELECTION: check in « CHANNELS » the chan-
nel(s) being used :

a. R : Right channel

b. Left channel

c. R+L : both Left and Right channels

C) DELAY SET-UP: if the subwoofer is placed between the main spea-
kers and the listening spot or at a shorter distance to the listening spot
than the main speakers, the adjustment of the DELAY will improve the
sound result by entering in DELAY the difference between two distances.
The distance d1 is the radius of the circle passing by both main speakers
tweeters, the listening spot being its centre, d2 being the distance bet-
ween the sweet spot and the subwoofer ((4) scheme). The result r= d1-
d2 is the value to enter in the DELAY section if positive. If d2 is higher
than d1, then leave DELAY on “0” and go to the PHASE SECTION for
precise setting.

D) SELECTION OF THE LOW PASS FILTER FREQUENCY

The upper limit of the subwoofer’s frequency depends upon the type of
use of the subwoofer, the main speakers’ characteristics and the setting
possibilities offered by the AV-amplifier involved in the system:

5.1, 6.1, 7.1 set-up for single LFE channel reproduction with full range

speakers for the other channels. The LFE channel is monitored by the pro-
cessor of the AV amplifier, we therefore advise to set the low-pass filter
of the Santorin 30 on 200 Hz to avoid overlapping of both filters.

Multichannel set-up with satellites speakers requiring back-up of a sub-
woofer for reproduction of the bottom-end frequencies: adjust the low-
pass filter of the Santorin 30 on 200 Hz, then go in the SET-UP menu
of the AV amplifier, set the speakers sizes on SMALL when required
and set the cross-over frequency between subwoofer and satellites spea-
kers as close as possible to the characteristics of each satellite. Regarding
Cabasse speakers, select the frequency in the above table. If not listed
here, this frequency is available on the spec sheets of the products and
on www.cabasse.com

When the SET-UP menu allows only one cross-over frequency and

satellites with different roll-off frequencies are being used, then select the
highest frequency.

Stereo use with a stereo amplifier :

In this configuration the subwoofer and a pair of Cabasse satellites
speakers are connected to a stereo amplifier. Select the low pass frequency
in the above table and enter it into the set-up menu of the subwoofer.

An experienced installer will be able to select after measurements on site
other values than the ones we determined in our anechoic chamber,
taking into account the acoustical specifications of the listening room.

E) VOLUME ADJUSTMENT :when the set-up includes satellites spea-
kers, we recommend to first adjust the volume between the subwoo-
fer and the main speakers in stereo mode with a selection of music
rich in low frequencies. Once this set-up is achieved, adjust the LFE level
in the set-up menu of the AV amplifier. Further LFE levels adjustments
should be done in the AV amplifier and not in the subwoofer software.

F) PHASE ADJUSTMENT: it allows if necessary to flatten the fre-
quency response around the cross-over point. If the subwoofer is clo-
ser to the listening point than the main speakers, then leave the PHA-
SE on the 0° and adjust the DELAY. The right setting is the one giving
the highest perceived level of low frequencies. Try first 0°, then 180°
and 90°. Other values should be used by experienced installers with
the help of measuring equipment. Readjust the phase each time you
move the subwoofer or the main speakers and each time you select a
new cross-over frequency.

G) PARAMETRIC FILTERS:

Thanks to our long experience in digital sound processing, we have
developed for the Santorin 30 unique room corrections modules. When
a graphic filter proposes volume adjustments on fixed bandwidth, our
parametric filters offer more precise and more natural settings, being per-
fectly focused on the critical zones. Sometimes the room acoustics
requires the use of only one parametric filter where a graphic filter will
in any case be active all along the bandwidth of the subwoofer and
create phasing shifts.

G1) AUTOMATIC ROOM EQUALISATION (5) (6)

1) Check that all the above settings are done and recorded.

2) Select « PRESET 2 » for the first adjustment in order to keep « PRE-
SET 1 » as a reference.

3) Unpack the measurements tools delivered with the subwoofer: micro-
phone, microphone-preamplifier, stand, power-supply, 2 cables

4) Place the microphone at the height of the listening point (P1 on dra-
wing (6)), connect it to the microphone-preamplifier “INPUT” with the
supplied XLR-XLR cable.

5) Connect the preamplifier to the Santorin by connecting its out-
put XLR « OUTPUT » to the input XLR « RIGHT »

6) Set the « GAIN » and « OUTPUT » levels of the microphone’s
preamplifier at 12 o’clock and press down the 48V key. Power the
preamplifier by connecting the power supply to the 9 VAC input and
to a mains plug

7) In the subwoofer set-up :

a. Select « RCA+HL » as « SOURCE » in order to prevent any risk of
Larsen effect (whistling)

b. « CHANNELS »+ « VOLUME »: The software automatically selects
the right XLR input as the microphone input and runs the level control.

c. In «AUTO ACQUISITION », press enter to confirm the measurement
process.

d. « Start Acq. 1 ? » :

Check that the microphone is right in the height of the listening

spot (P1).

d2. Press « ENTER » to launch the measurements acquisition 1
