ADDITIONAL SWITCHING SYSTEM® | OVERVIEW The Additional Switching System® begins with the Rack and Power Supply. Tip: , It always comes with at least one factory installed module (you wouldn’t want an empty rack, would you?) [The Dangerous Music Additional Switching System® Rack with one blank panel and Power Supply pictured above] Then the selection of one or two modules per rack.
4 | DANGEROUS MUSIC And the final outcome... [The cornucopian Additional Switching System® loaded with DAC-SR and Uniswitch pictured above] [The Additional Switching System® loaded with one DAC-ST and blank panel pictured above. Any combo possible.] Up to two Additional Switching System® racks may be utilized simultaneously, providing a maximum of 4 modules.
ADDITIONAL SWITCHING SYSTEM® | REMOTE CONTROL All Additional Switching Modules are controlled by the Dangerous ST Remote. [Half of the Monitor ST Remote pictured above] On the Monitor ST Remote, first use the “UP” and “DOWN” buttons to select the appropriate bank. The Remote’s LEDs will verify which bank is active. Then choose the input by using the “Additional Switching” 1-4 buttons. This is how the Additional Switching remote buttons can control up to 4 devices.
6 | DANGEROUS MUSIC DAC-ST Front Panel Features & Benefits The DAC-ST expands your digital connectivity while maintaining the instantaneous control and pristine reference standards that Dangerous Music is renowned for. The DAC-ST is a stereo D/A converter that allows the engineer to monitor from and switch between any one of the five digital sources without interruption. The source is selected from the Dangerous ST Remote and simultaneously routed to the Selected Digital and balanced Analog Outputs.
ADDITIONAL SWITCHING SYSTEM® | you can keep on mixing the music, while we handle the technology. Note: At the time of printing, the M-Audio 2626 was the only piece of gear known not to comply with the standards above and therefore requires the use of a bi-directional S/PDIF to AES transformer. 3. Digital Input Selected LEDs Feature: Visual confirmation that a specific digital source has been selected by the Monitor ST Remote. Yellow LED on = source selected. Yellow LED off = source not selected.
8 | DANGEROUS MUSIC Operation: To align the unit, select a 1kHz digital sine wave and feed it at the desired level. Using a flathead screwdriver, gently turn the front panel trim pots until they measure +4 dBu at the output. Clockwise to increase output, counterclockwise to decrease it. Tip: , The DAC-ST comes aligned from the factory with a maximum output level of +22dBfs (-18 dBfs=+4 dBu). Don’t know what this all means? Contemplating audio suicide? 7.
ADDITIONAL SWITCHING SYSTEM® | MONITOR ST & DAC-ST Rear Panel Features & Benefits Next we’ll review how to hook these audio tools up to play nicely together. 1 2 3 [The rear of the A.S.S.® DAC-ST stereo digital to analog converter / switcher module pictured on previous page] 1. Digital In/Thru Feature: The rear panel of DAC-ST sports a DB25 connector wired to the Tascam / Digidesign AES digital standard. Remember, this connector can be wired for AES or S/PDIF or any combination of the two.
10 | DANGEROUS MUSIC •Compare the effected version. Pass through back into Pro Tools and effect with plugins. •Compare against the original and hardware effected versions. Pass through to an external recorder. •Compare the output of the final recorder with all the aforementioned sources. Now make accurate, critical decisions based on true comparisons. Pass through to a digital meter or see tip below. 2. Selected Digital Out Feature: Connect a digital meter here.

12 | DANGEROUS MUSIC 1. D-Sub to Digital in/out snake: What: Connects 4 stereo pairs of digital i/o. Example: 25-pin D-Sub on one end, eight XLRs on the other (4 female connectors for stereo input and 4 male connectors for stereo out/thru). See photo A for visual confirmation and Appendix for wiring diagram. This conforms to the Tascam / Digi wiring standard. , Tip: , Tip: Remember, this may be wired for AES or S/PDIF or any combination, without transformers.
ADDITIONAL SWITCHING SYSTEM® | 13 4 [The rear of the Monitor ST/SR Remote pictured above] 4 & 5. Shielded Ethernet Cable: What: Ethernet CAT 5e shielded cable connects 4 and 5, bridging the Monitor ST remote and Additional Switching Rack®. Example: The remote connects to the Additional Switching Rack® with shielded CAT 5-e cable. It may safely be up to 100 feet long. Come out of the remote, into the “REMOTE IN” jack.
14 | DANGEROUS MUSIC DAC-SR Front Panel Features & Benefits The DAC-SR expands your digital connectivity while maintaining the instantaneous control and pristine reference standards that Dangerous Music is renowned for. The DAC-SR is a 6 channel D/A converter that allows the engineer to monitor from and switch between any one of the four digital 5.1 sources without interruption. The source is selected from the Dangerous ST-SR Remote and simultaneously routed to the balanced Analog Outputs.
ADDITIONAL SWITCHING SYSTEM® | 15 1. Digital Input Selected LEDs Feature: Visual confirmation that a specific digital source has been selected by the Monitor ST-SR Remote. Yellow LED on = source selected. Yellow LED off = source not selected. Benefit: Avoid putting post-its on all your gear to remember the combinations-- what? I already forgot... 2. Input Button Feature: This button toggles Input 4 between TOSLINK multichannel ADAT and stereo optical.
16 | DANGEROUS MUSIC Operation: On the Monitor ST Remote, first use the “UP” and “DOWN” buttons to select the appropriate bank. The Remote’s LEDs will verify which bank is active. Then choose the input by using the “Additional Switching” 1-4 buttons. That’s how the Additional Switching remote buttons can control up to 4 devices. (More than just black magic). See the Remote ST-SR section for photo ops and visual alacrity. 6.
ADDITIONAL SWITCHING SYSTEM® | 17 1. AES & S/PDIF Digital In/Thru Feature: The rear panel of DAC-SR sports two 25 pin D-Sub connectors (commonly called DB25s) wired to the Tascam / Avid AES digital standard. Remember, these connectors can be wired for AES or S/ PDIF or any combination of the two. Up to a 24 bit depth with sampling rates from 32 kHz-192 kHz are supported. (The pinout wiring diagram resides in the appendix of this manual.) Benefit: (A) Provides instantaneous switching between two 5.
18 | DANGEROUS MUSIC Feature: 2A. TOSLINK Multi-channel Inputs Feature: Two TOSLINK inputs accept optical multi-channel feeds of up to 24 bits with sampling rates from 32 kHz-96 kHz. Benefit: Accept multiple rates with no conversion and avoid the crack, snapple, pop of digital reclocking. 2B. Digital Input 4 Feature: Input 4 is switchable between stereo optical (S/PDIF) and multichannel audio.
ADDITIONAL SWITCHING SYSTEM® | 19 UNISWITCH Front Panel Features & Benefits Involved with music for television, film scoring or broadcast sound? Undoubtedly you own as many video sources as audio. The Uniswitch provides instantaneous switching between multiple video sources, all controlled from the versatile Dangerous Remote. The Uniswitch controls any Gefen 4x1 switcher equipped with the RS232 input connector. In fact, the techs at Dangerous Music can customize the Uniswitch to control ANY RS232 device.
20 | DANGEROUS MUSIC “Additional Switching” 1-4 buttons. That’s how the Additional Switching remote buttons can control up to 4 devices. (More than just black magic). Refer to the remote section for more 411 (i.e. information) and a photo op. UNISWITCH Rear Panel Features & Benefits 1 [The Dangerous Music Uniswitch rear panel pictured above] 1.

ADDITIONAL SWITCHING SYSTEM® | 24 MODULE INSTALLATION CONTINUED... Tip: , This is only necessary if you purchase additional modules for a rack you already own. Each module will have specific installation instructions, the following serves as an example. STEP 1. Organize all the loot: Confirm you have (as numbered in the previous photo ops): 1. DAC-ST board with rear panel 2. DAC-ST front panel 3. Four #6-32 x 3/8” pan head stainless steel machine screws (board to chassis) 4.
25 | DANGEROUS MUSIC Tip: , •Using a #2 phillips head screwdriver, remove the four #6-32 x 1/4” black screws in the rear plate (5). Put the screws somewhere where they won’t roll into the shag carpet like a recycled Trader Joes Salsa Cruda container. You’ll need these in a minute. STEP 4. Installing the board •Where you just removed the rear panel, slide the board and rear panel assembly (1) through the rectangular opening.
