11.3 THRESHOLD ADJUSTMENT

If

ALC

(Automatic Level Control) is

ON

and the

ALC THRESHOLD

is set to

USING +/- KEYS

(see SETTINGS MENU, ALC THRESHOLD), the threshold during

RECORD

or

STOP

can be

adjusted by pressing the

+

or

-

keys (8 or 7). Once one of these keys is pressed, an additional bar-

graph on the right side of the display, indicating

THR

appears, showing the current position of the

adjustment.

74dB

corresponds to maximum threshold level,

104dB

corresponds to minimum

threshold level.
The

THRESHOLD

adjustment permits selection of the size of the compression zone. It is the lower

limit setting of the zone that will be automatically amplified during a silent period. The ALC works in a
range of 42dB (from 74dB to 116dB). If the

THRESHOLD

is set to 104dB, signals of 104dB and

higher (max. 116dB) will be recorded at 0dB level (between 2dB and 6dB for a stable signal). A
signal of 90dB will be recorded at 14dB (104dB  90dB).

11.4 WHAT IS DBSPL

The term dB SPL is the unit used to indicate the power of
ambient sound. dB is the abbreviation of decibels (ten bels),
which is the logarithmic ratio of a signal versus a reference level. "SPL" indicates the reference level
and stands for "Sound Pressure Level". The reference level is an air pressure of 20 micropascal
(0.00002 Pa = 0 dB SPL).

Some indicative values:

30-40 dB SPL: ambient room noise / whispering
50-70 dB SPL: normal conversation
80-90 dB SPL: feature film soundtrack in a theatre
90-110 dB SPL: busy bar with live music (Swiss legal max is 110 dB in a public arena)
110-120 dB SPL: heavy rock concert
130-140 dB SPL: Threshold of pain for the human ear

If the gain of the microphone is correctly set, the ARES-P II

+

 could be used as a sonometer. The value

indicated by the modulometer of the ARES-P II

+

 is the peak value (dB SPL

peak

). The peak value is

typically 10 dB higher than the RMS (Root Mean Square) value.

Examples:

Input attenuation set to 90dB, modulometer shows 0dB, this means that the sound has a pressure
level of 90dB SPL

peak

80 dB SPL.

Input attenuation set to 74dB, modulometer shows 12dB, this means that the sound has pressure
level of (74 12) 62dB SPL

peak

52dB SPL

Finally, if you know that you are going to make a recording of a sound level of 90 dB SPL (100 dB
SPL

peak

) then you can pre-adjust your machine by setting the level pot to the 100 db position and in

this way, your recording will not overload and you will record at about 0 dB on the modulometer.
