Page 36 AP20 Installation and Operating Guide Page 36 Figure 15. Channel Names Screen When channel assignments are complete, you can eliminate the unassigned channels so they do not appear on the main screen. Turn off the Vu indicator for unused channels.
Page 37 2.9.6 Verify Channel Assignments in Auditorium On the AP20, select a channel and turn on Pink Noise. In the auditorium, verify that the Pink Noise output is coming from the correct loudspeaker(s). Do this for all channels. For details, see Audio Levels, page 94.
Page 38 AP20 Installation and Operating Guide Page 38 Caution: Before proceeding with the room equalization, it is imperative that the loudspeaker and crossover systems be properly aligned. Issues like speaker phasing and horn tilt need to be checked. When using crossovers the low, mid and high frequency drivers must be balanced to produce a relatively even response from 100 Hz to 5 Hz.
Page 39 * Subwoofer should be set to 10 dB of in-band gain (see SMPTE RP-200), which equates to approximately 91 dBC (slow). If not possible to achieve the baseline, use the AP20 (Analog Output Levels) to make minor adjustments. AP20 Installation & Operating Guide...
Page 40 If using Dirac Live, please refer to the Dirac Live Theater Setup manual. For an overview, see Using Dirac Live® to Tune the Auditorium, page 44. The AP20 contains a full suite of 1/3 Octave EQ filters that are “traditional” cinema processor filters. If using AP20 1/3 Octave EQ, complete the following steps.
Page 41 AP20 Installation and Operating Guide Page 41 5. Turn on XCurve Display. Try to tune the frequency pattern to the XCurve. If the pattern does not conform – there is a hole or a peak or other variance – then select the frequency that needs adjusting, and push it down or pull it up.
Page 42 2.11 Subwoofer EQ – Parametric EQ The AP20 features Parametric EQ on every channel. Parametric EQ is an optional adjustment and is in addition to 1/3 Octave EQ. It is only available with low frequencies and offers more control than 1/3 Octave EQ.
Page 43 AP20 Installation and Operating Guide Page 43 Figure 21. Parametric EQ Screen, Filter Enabled 2.12 Copy EQ Set to Another EQ Set This screen is used to copy the EQ settings for all channels to a new EQ set under a new name. After equalizing all the channels, copy these settings to create another EQ (with a new name).
Page 44 To do this, save the setup configuration on a memory stick (USB Flash drive), then use the saved setup to copy to the AP20 for the next screen, since many or all the values will be the same.

The input indicator turns green when there is a low signal applied to the pin. To verify that the AP20 is properly receiving an input from an external source you would need to make the external device send a low signal on that pin. Then confirm that the signal is received by the AP20 by checking if the corresponding circle turns green.

Page 144 AP20 Installation and Operating Guide Version 1.25 16-Channel Upgrade (H332 Card) The 8 channel AP20 may be upgraded to 16 channels by adding the H332 circuit card. Order P/N 9030H33200 latest version. H332 Card Installation Tools required: Phillips head #2 screw driver Caution: The H332 card contains parts that are static sensitive.
Page 145 This card offers two inputs (Projector 1 & 2), see Figure 1 below. Both inputs have an LED to indicate which input is active. The automation in the AP20 must be programmed to switch the inputs at the proper time. In addition to these inputs, there are two Lt/Rt test points. These are BNC type connectors that are used for alignment of the projectors optics.
Page 146 Turn off the AP20’s rear panel power switch and unplug the power cord. • Remove one of the three cover plates from the AP20 option slots. All slots are identical. • Slide the H338 card into the card guides of the option slot and gently push the card into its mating connector.
Page 147 6 channel assignments and trim values flat. If the H338 card is not factory installed, Optical formats must be created in the AP20 before the H338 can be used. The optical format must have the analog input source selected as Optical. The H338 card supports standard optical film soundtrack formats: Mono, A-type and SR-type.
Page 148 AP20 Installation and Operating Guide Version 1.25 F3.2. Assign Optical Formats to Format Buttons After creating the optical formats, they may be assigned to “Format Buttons”. The format buttons will then appear on the Home screen and be available for selection. In Figure 4 below, SR is selected.
Page 149 AP20 Installation and Operating Guide Version 1.25 F3.3. Input Source Selection Select the Input Source button. This will open the Input Select screen. Each of the optical formats must be set to have Optical selected as their input source. In the example in Figure 6 below, SR will have its input source set to Optical.
Page 150 Inputs from the film are on the left. The resulting channels are on the right side, and are internal to the AP20. Note that these are not necessarily the output channels as they and may be routed on the AP20 output (see Section 2.9.4 Assign Channels on AP20 in this manual).
Page 151 AP20 Installation and Operating Guide Version 1.25 In this example, left total (LT) and right total (RT) are the inputs. Outputs are: 1L = channel 1 is left, 2R = channel 2 is right, 3C = channel 3 is center, 4Lfe = channel 4 is bass, 5Ls = channel 5 is left surround, and 6Rs = channel 6 is right surround.
Page 152 LED voltage and adjust it if necessary, as per the manufacturer’s recommended procedure. F4.3. Wiring and Connections Projector 1 & 2 inputs on the AP20 are 9-pin female D-connectors. See Figure 8 below for pin assignments. Input from the solar cell is a 9-pin Male D-connector. PIN NO.
Page 153 The right channel is nearest the edge of the film. To confirm proper wiring, while observing the projector output on a RTA or the AP20 setup screen, place a business card or similar object to block the side of the cell nearest the edge of the film. You should detect a large drop in the right channel level.
Page 154 Allen/Hex Wrenches, small screw driver etc. On the AP20 select one of the optical formats in the home screen, next select Menu (System) → Formats → Format Options → Film Options → Film Setup. You should now be in the Film Card Setup screen as shown in .
Page 155 Consult your projector’s manual for more information. To close this window, press Dismiss. To manually adjust levels, select the button below the left input level bar and use the AP20 front panel adjustment knob to increase or decrease this level until it meets the reference line.
Page 156 Figure 14 – Crosstalk using Cat 97 test film Note: while running the CAT 97 test film you can also select Azimuth in the AP20’s optical set up screen. If alignment is correct you should be able to observe a cross on the screen as shown in Figure 15.
Page 157 Correct Figure 16 – Azimuth This can also be viewed on the AP20 screen by going to Menu (System) → Formats → Format Options → Film Options → Film Setup and Selecting Azimuth (see Figure 15). When Azimuth is selected, on the right a pictorial of the azimuth adjustment is shown.
Page 158 AP20 Installation and Operating Guide Version 1.25 Figure 17 – Focus After the flattest response is achieved by adjusting the projector optics, the final slit loss correction is made using the Parametric Filter Settings, see Figure 18. F4.4.5. Slit Loss EQ When Slit Loss EQ is selected a graph of the slit loss adjustment is shown on the right of the screen (see Figure 18 below).
Page 159 Soundtrack Input Figure 19 – Digital Soundtrack Input None is use when the AP20 analog and digital input connectors are not used for the film digital soundtrack. Digital Channels 1->8 select this if the film digital soundtrack player is connected to the AP20 Digital Input channels 1-8 connector.
Page 160 RTA. Select an optical format on the AP20, enable pink noise on the center channel, and note the level and low frequency roll off displayed on the RTA. Select the appropriate Low Pass Filter setting by pressing that button and using the fader knob to make any changes required to match the low pass filter to the roll off measured.
Page 161 Next turn on the subwoofer channel, enable pink noise on the LFE channel, and then select the Bass Gain by pressing the <Gain> button. Use the AP20 fader knob, or up and down keys when using a laptop, to adjust the Bass Gain to match the Center channel level previously noted on the RTA display.
Page 162 Version 1.25 Appendix G: Connecting Two AP20 units Two AP20 units can be linked together serially. When this is done the two units work in unison locking their format, fader level, and mute selection. Both AP20 units must have matching format names. The names must match exactly although their format profiles may be different.
