WOrkING WITH THE i7600
Controls and Display
the i7600 consists of two modules: Eq Module and rta Module. the Eq Module has four control modes, and the rta Module has three. the behaviors of the control knobs and the displayed information on the i7600 depend largely on which module and control mode is being used. identifying your current control mode is the key to master the behaviors of the controls. table 1 is designed to help you learn how to identify the current control mode.
Band Level Display
the most prominent parts on the face the i7600 are the two wide panes of Band level Display. See figure 1 for an illustration of the front panel. the left pane is for displaying frequency and level information of channel 1, and the right pane is for channel 2. inside either pane are 30 columns of lEDs that represent the 30 iSo-standard bands of the audio spectrum in 1/3-octave intervals. Directly below every column is a number that indicates the center frequency of the band.
Alphanumeric Display
Between the two panes of Band level Display is a two-line alphanumeric lcD. what information is shown in the alphanumeric Display largely depends on the current control mode. there is, however, a closely followed rule: the upper line displays the
system-wide or channel-specic status, whereas the lower line provides either the band-specic
information or the names and values of various functions.
Clip warning
when a high-level signal exceeds the maximum capability of the unit, the signal is automatically compressed (clipped) in order to prevent damages to the system circuitry. when clipping occurs in one or both channels, a warning message is shown in the alphanumeric Display. table 2 describes the possible messages for clip warning.
Display Meaning
clip1 clipping at channel 1 clip2 clipping at channel 2
clip1+2 clipping at both channels
table 2: clip warning messages if clip warnings often appear in the alphanumeric
Display, try to reduce the signal level to prevent audio distortion. a real-time spectrum analyzer, such as the i7600 rta Module, is the ideal tool for identifying the frequency that is being clipped. the
i7600 can also help you nd out whether the clipped
signal is at the input (Pre EQ) stage or the output (Post EQ) stage.

EQ/rTA switch and indicator
pressing the EQ/rTA button lets you switch between the Eq Module and rta Module. the accompanying green lED lights up when you are in the rta Module.
GrAPHIC EDIT control
the behavior of this control knob depends on the current control mode. generally, this knob adjusts
the band-specic settings. We will discuss this
control in greater detail later.
Bypass switch and indicator
pressing the Bypass button lets you switch the bypass function on or off. when a channel is bypassed, as indicated by the accompanying red lED, none of the Eq settings are applied to the input signal of that channel. as a result, the signal you get from the channel output is identical to the original input signal. this feature lets you make a quick comparison between the original and processed sounds. it is particularly useful when you are setting up your system.
notE: the Channel Link status affects the behavior of the Bypass button. when Channel Link is on, pressing the Bypass button affects the bypass status of both channels. when Channel Link is off, however, which channel will be affected by the Bypass button is determined by the location of the cursor (that is, the blinking lED in the Band level Display, or the left-most blinking lED in a multiband group). if the cursor is in the left pane, pressing the Bypass button affects only the bypass status of channel 1. likewise, if the cursor is on the right pane, pressing the Bypass button affects only the bypass status of channel 2.
fuNCTION EDIT control
the behavior of this control knob also depends on the current control mode. generally, this knob adjusts
the system-wide and channel-specic settings. We
will discuss this control in greater detail later.
THE EQ MODuLE
functions
Controls and Display
To edit a single band
with the Eq/rta indicator off, turning or pushing the GrAPHIC EDIT knob will bring you to the Eq Band Select Mode. See table1 for tips on identifying the control modes. to select a band, simply turn the GrAPHIC EDIT knob. the selected band is the one that has a slow-blinking lED (the cursor). to change from channel 1 to channel 2, turn the GrAPHIC EDIT knob clockwise until the cursor "jumps" to the right pane. once a band is selected, you can edit its boost/cut level by pushing the GrAPHIC EDIT knob once. the cursor will blink faster to indicate that you are now in the Eq Band Edit Mode. while in this mode, turning the GrAPHIC EDIT knob will boost or cut the gain level of the band. after you are done editing the band level, push the GrAPHIC EDIT knob once again to return to the Eq Band Select Mode.
To edit a multiband group
while in the Eq Band Select Mode, turning the fuNCTION EDIT knob lets you select multiple bands as a group. for example, if the lED is originally blinking only at the 10k band of channel 1, turning the fuNCTION EDIT knob clockwise by two notches will make these three lEDs blink: 10k, 12.5k, and 16k. if instead of two notches, you
turn the knob clockwise by ve notches, you will
notice that the blinking lEDs are no longer limited to channel 1 (at 10k, 12.5k, 16k and 20k hz), but also include two bands of channel 2 (at 25 and 31 hz). this means you can group across the channels even when Channel Link is off. in practice, you may often want to raise or lower the boost/cut level of the entire spectrum of both channels. this cross­channel grouping makes the task quick and easy without having to link the channels.
once a group is selected, push the GrAPHIC EDIT knob to enter the Eq Band Edit Mode; notice the lEDs are blinking faster. now turn the GrAPHIC EDIT knob to edit simultaneously the boost/cut level of all selected bands. push the GrAPHIC EDIT knob again to return to the Eq Band Select Mode.
with the EQ/rTA indicator off, pushing the fuNCTION EDIT knob once will bring you to the Eq function Select Mode. See table 1 for tips on identifying the control modes. while in the Eq function Select Mode, the upper line of the alphanumeric Display provides important information on the current Eq
settings. This information includes the following ve
values.  program number: P1 through P30 are factory-
set programs, and u1 through u30 are user-
dened programs.
 Low-pass lter: The letters LPf appears
when the low-pass lter is active. This value is
channel dependent.
 High-pass lter: The letters HPf appears
when the high-pass lter is active. This value
is channel dependent.
 gain: G+ indicates that a gain increase is been
applied to the output; G– is for gain decrease; and G= is for zero gain. this value is channel dependent.
 channel link: appears when the channel link
is on. otherwise, is displayed.
the lower line of the alphanumeric Display shows a function name and its current value. when you are in the Eq function Select Mode, the entire
lower line is ashing. This is to remind you that, if
you turn the fuNCTION EDIT knob now, you will be "scrolling" through the function menu. turn the
fuNCTION EDIT knob to nd the function that you
want to edit. press the fuNCTION EDIT once to enter the Eq function Edit Mode. notice that the
function name is no longer ashing and that only
the variable value is. turning the fuNCTION EDIT knob now will change the value for that function.
When you have nished adjusting the value, press
the fuNCTION EDIT knob again to return to the Eq function Select Mode.
the following sections describe all functions you can adjust in the Eq function Edit Mode.

English
Channel Link
when this function is set to On, all settings of channel 1 are copied to channel 2; and all subsequent adjustments will be simultaneously applied to both channels. when Channel Link is Off, you can adjust each channel separately; the location of the cursor determines which channel is to be affected. when the cursor is in the left pane, the adjustment is made to channel 1; and when it is in the right pane, channel 2 is affected.
Gain
this function lets you increase or decrease the gain level of the channel output. the range of control is from negative innity to +6 dB. When Channel Link is set to Off, you can adjust the gain level for each channel separately.
Low-Pass filter (LPf)
A low-pass lter lets you "cut out" the unwanted high
frequencies. You may set the threshold frequency anywhere between 1 khz to 20 khz in 1/6-octave
intervals. Alternatively, you may remove the lter
by setting it to Off. this function is channel dependent.
High-Pass filter (HPf)
a high-pass lter lets you "cut out" the unwanted low frequencies. You may set the threshold frequency anywhere between 20 hz to 1 khz in 1/6-octave
intervals. Alternatively, you may remove the lter
by setting it to Off. this function is channel dependent.
Store
this function lets you store your favorite settings. You may store up to 30 programs, from u1 to u30. information stored in a program includes all following values for both channels: the channel-link status, gain levels, low-pass-? lter frequencies, high-pass­? lter frequencies, and boost/cut levels of all bands. appendix B provides 30 blank diagrams for you to record your stored programs.
key Lock
the lock function can be activated by simply pressing the graphic and function Edit controls simultaneously. Enabling locking means that you are then unable to change any settings of the i7600 until you have unlocked it once more. this helps prevents accidental alteration of settings while the device is in use. to turn the lock off, once again press the graphic and function Edit controls simultaneously.
Auto Store
if the controls on the i7600 remain unused for more than 10 seconds, your current settings will automatically be saved and will be stored, even after the power is turned off. this ensures that your settings are never lost in unexpected power outages and that you get the settings you desire most on start up.
recall
this function lets you recall a previously stored program. this is an easy way to set up your Eq; it is especially useful during live events that often call for quick changes to the Eq settings in etween songs. You may recall any of the 60 stored programs (30 factory-set programs, from p1 to p30; and 30 user­de? ned programs, from u1 to u30). See appendix a for all factory programs. See also appendix B for blank diagrams where you can record your favorite settings.
caution: when you recall a program, the current Eq settings of both channels will be lost, regardless of the channel-link status. if you plan to use the current setting in the future, consider storing it before performing a recall.
THE rTA MODuLE Controls and Display
with the EQ/rTA indicator on, turning the GrAPHIC EDIT knob brings you to the rta Band
Select Mode. See table 1 for tips on identifying the control modes. continue to turn the knob to select a band. the selection is indicated by the blinking cursor at the bottom row of the Band level Display. once a band is selected, the alphanumeric Display provides the following three pieces of information: the channel number (Channel 1 or Channel 2), the center frequency of the band, and the real-time level (if Peak hold is off) or the peak level (if Peak hold is on) of the band.
notE: in the rta Module, the right-most lED column (marked 20k) in each pane of the Band level Display does not show the level of the 20­kilohertz band; rather, it shows the over-all level of the channel. to avoid confusion, special markings
are printed above the two 20k columns (▼lEV) and at the center-bottom of the front panel (▼rta/
ch lEVEl), reminding you that these two columns show the channel levels in the rta Module.
functions
with the EQ/rTA indicator on, turning the fuNCTION EDIT knob brings you to the rta function Select
Mode. See table 1 for tips on identifying the control modes. while in the rta function Select Mode, the upper line of the alphanumeric Display provides important information on the current rta settings.
This information includes the following ve values,
all of which are system-wide (channel-independent) values.
 The rst two values indicate the viewing
range of the Band Level Display. The rst
value represents the maximum level that can be represented in the Band level Display. in other words, it corresponds to the top lED in each column. the second value, on the other hand, represents the minimum level, and corresponds to the bottom lED.
notE: the reference marks (+12, 0, and -12) beside the panes of the Band level Display are applicable only in the Eq Module. while in the rta Module, the reference values for the top and bottom lEDs are adjustable, and are shown in the alphanumeric Display as described in the previous paragraph.
 weighting type: the letter A stands for a
weighting, C for c weighting, and f for at.
 Signal source: the word Post indicates that
the current measurement is taken from the processed (post-Eq) signal, whereas Pre indicates that the measurement is taken from the original (pre-Eq) input signal.
 pink noise: the letter P appears when the
Pink noise function is set to ON.
the following sections describe all functions you can adjust in the rta function Edit Mode.
range
this function lets you select the viewing range of the Band level Display. two values are associated
with each selection. The rst value represents the
maximum level that can be represented in the Band level Display. in other words, it corresponds to the top lED in each column. the second value, on the other hand, represents the minimum level, and corresponds to the bottom lED. table 3 lists all available viewing ranges.
MAX MIN
+ 30 - 6 + 21 - 15 + 12 - 24 + 6 - 30 0 - 36
- 12 - 48
Table 3: Viewing ranges
Use this function to nd the appropriate viewing
range for your program. for instance, when there is little or no action in the Band level Display, and you are certain that signals are being fed into at least one of the channels, you probably have set a range that is too high. in other words, all the activities are happening below the viewable range. try lowering the range to resolve the problem.
English
7i7600
8 i7600
English
on the other hand, if you see the top lEDs in most of the bands are often lit, you probably have set a range that is too low. try raising the range to see whether the problem is resolved. if the problem continues even when the highest range is selected, try to lower the gain setting in the Eq Module (if the measurement is post-Eq) or the output level of the source device (if the measurement is pre-Eq).
response Time
this function determines the length of the time span within which measurements are averaged. the average value of each interval is represented by the height of the lit lED in a column. in effect, the value you choose for the response time will determine how fast the lEDs respond to the changes in sound intensity.
Different types of sound have different rates of change in intensity. in order to see a faithful representation of the sound on the lED display, you need to adjust the response time according to the type of sound that is being measured. choose, for example, a short response time for a fast-attack and fast-decay sound, such as snare-drum beats; but opt for a longer response time for the long-sustaining sound of a typical wind instrument.
Because of this effect, the scale of a sound­level meter must be "weighted" in order to better represent the loudness as perceived by an average person. the i7600 offers two types of weighting: the A weighting is designed to represent human hearing for low-level sounds, at 40 phons (40 dB Spl at 1 khz); whereas the C weighting mimics the hearing for high-level sounds, at 100 phons (100 dB Spl at 1 khz). when you want to measure the straightforward Spl of the signal, remember to set the Weighting type to f (flat) for the un-weighted scale.
unit of Measurement (dBu/dBV)
this function lets you choose the unit of measurement for the signal level. the unit dBu is referenced to
0.775 volts rMS (0 dBu = 0.775 V), whereas the unit dBV is referenced to 1 volt rMS (0 dBV = 1 V).
Peak Hold
when this function is set to ON, the highest level reached in each band is indicated by an lED that stays lit in the corresponding column in the Band level Display. this lit lED will hold its position in the column until it is "pushed up" by a higher-level signal in the band.
options for the response time are: 35 ms, 125 ms, 250 ms, 500 ms, 1 second, and 2 seconds.
Weighting Type
the human ear responds differently to sounds at different frequencies. Even when the sound pressure level (Spl) is identical at all frequencies, an average person tends to hear a louder midrange sound as compared to the bass or high-frequency sounds. however, as the Spl is increased equally at all frequencies, the perceived loudness difference between the midrange and bass sounds becomes less predominant, and the difference between the midrange and high-frequency sounds becomes more apparent.
Signal Source (Pre EQ/Post EQ)
this function lets you choose which signal is to be measured. Set to Pre EQ if you want to measure the input signal in its original, unprocessed form. on the other hand, if the processed (equalized) sound is what you want to measure, then Post EQ is the choice.
Pink Noise
the i7600 can generate a continuous stream of pink noise to help you calibrate your system. turn on this function to send out the signal stream through the PINk NOISE OuT connector in the back of the unit.
