INSTALLATION PROCEDURES 3-2) GROUNDING 3-2a) GROUNDING OVERVIEW An audio installation is only as good (or bad ) as its grounding system. Poor grounding practices are the number one cause of RF interference, hum, crosstalk and noise.
INSTALLATION PROCEDURES 3-2) GROUNDING (continued) 3-2b) CONSOLE GROUNDING The console has two parts. One is the console itself, the second is the power supply. POWER SUPPLY GROUND Since the power supply contains AC, the chassis of the power supply is connected internally to NEVER be defeated the third prong of the AC power plug (AC System Ground). This should through the use of a 3-2 prong adapter. If the chassis of the power supply is not grounded a serious shock hazard exists.
INSTALLATION PROCEDURES 3-2) GROUNDING (continued) 3-2c) GROUND LOOPS Modern audio consoles do NOT generate 60 or 120 cycle hum. Hum is caused by 60 cycle radiation from power supply transformers located too close physically to electronic equipment (generally 1"-6") or by GROUND LOOPS! A ground loop is a low frequency LOOP ANTENNA which picks up 60 cycles being radiated within the building from its AC power distribution system.
INSTALLATION PROCEDURES 3-2) GROUNDING (continued) FLOATING ELECTRONIC GROUND 3-2c) GROUND LOOPS (continued) CHASSIS GROUND Unbalanced source ground loop Electronic ground A typical ground loop is formed when Electronic Ground is connected within the product to Chassis Ground. Unbalanced semi-pro equipment is often built this way. Unbalanced equipment requires that Electronic Ground be connected through the audio signal cable between the two pieces of equipment.
INSTALLATION PROCEDURES 3-3) INPUT WIRING 3-3a) RECOMMENDED WIRE Only individually FOIL SHIELDED TWISTED PAIR cable is recommended by Arrakis Systems. Use of unshielded twisted pair such as multipair telephone cable is NOT recommended for a quality installation that will achieve the maximum possible performance from this console.
INSTALLATION PROCEDURES 3-3) INPUT WIRING (continued) 3-3d) LINE LEVEL TRANSFORMER BALANCED SOURCE OUTPUT TO ACTIVE BALANCED CONSOLE INPUT The Source Transformer Output wants to see a fixed impedance of generally 600 ohms for it to meet frequency response and distortion specifications. The Console Input is high impedance (>10,000 ohms). To match impedances, a 600 ohm resistor must be placed across the input of the console as shown below.
INSTALLATION PROCEDURES 3-3) INPUT WIRING (continued) 3-3f) UNBALANCED SOURCE OUTPUT THROUGH AN ISOLATION TRANSFORMER TO BALANCED CONSOLE INPUT In some situations an Isolation Transformer is required to solve tough RF Interference or ground loop problems where the Source Output is unbalanced. The Isolation Transformer must be impedance matched to both the source and the console.
INSTALLATION PROCEDURES 3-4) OUTPUT WIRING 3-4a) CONSOLE BALANCED OUTPUT TO ACTIVE BALANCED INPUT The console outputs are low impedance (>100 ohms balanced) and can therefore directly drive multiple high impedance inputs (>10k ohm) without a distribution amplifier. These active balanced (transformerless) outputs do NOT require a terminating resistor as a transformer balanced output would.
INSTALLATION PROCEDURES 3-4) OUTPUT WIRING (continued) 3-4c) CONSOLE BALANCED OUTPUT TO TRANSFORMER BALANCED INPUT The console Output is low impedance (<100 ohms) and can therefore directly drive only ONE 600½ input impedance transformer balanced input without a distribution amplifier. The transformer needs to see a 600 ohm balanced driving impedance for accurate frequency response and low distortion. Each console Output has a 47½ series resistance already built in.
INSTALLATION PROCEDURES 3-4) OUTPUT WIRING (continued) 3-4e) CONSOLE OUTPUTS TO TELEPHONE LINES Under NO circumstances should a console output be used to directly drive telephone lines. The console outputs WILL be destroyed most likely by lightning. A telephone company approved coupler or (preferably) a telephone hybrid MUST be used. Arrakis Systems doesn‘t, under any circumstances, warranty damage due to lightning or any telephone line transients.
INSTALLATION PROCEDURES 3-4g) CONSOLE WIRING - CRIMP TOOLS & CRIMPS Good crimps are mandatory for reliable console operation and clean signal path. It pays to be extra careful in crimping right from the beginning. A good crimp now may save many hours of frustration later. A good crimp will exclude air from the joint. If air gets in the crimp joint oxidation can occur resulting in an intermitant contact.
INSTALLATION PROCEDURES 3-5) CONSOLE OVERALL INPUT/OUTPUT CONNECTOR DIAGRAM The diagram below illustrates a summary of the basic audio I/O and logic connectors for the 10 channel 1200 Series Console. The 5 channel and 15 channel consoles are similar. The following pages examine these connections in detail.
INSTALLATION PROCEDURES 3-6) MONO MIC INPUTS Unless specified differently upon order, channel one will be a mono MIC channel and the remaining channels will be stereo line level channels. Channels cannot be converted from mic to line in the field. Upon initial order, any of the channels can be specified mic or line. Additional channels may be converted to MIC by contacting Arrakis service. a) LEVELS The mic trimpot will adjust gain by roughly 30dB . The trimpots are factory set for -55dBu input levels.
INSTALLATION PROCEDURES 3-7) STEREO LINE LEVEL INPUTS a) LEVELS The audio trimpots will adjust levels from -10dBV to +8dBu for consumer and pro sources. The trimpots are factory set for +4dBu input levels. b) INPUT IMPEDANCE The 1200 stereo line inputs are high impedance active balanced design (>10,000 ohm input impedance c) CONTROL LOGIC STEREO LINE INPUT CONNECTOR 1) REMOTE START An isolated, momentary reed relay closure (50 mA max) is provided for remote start of sources.
INSTALLATION PROCEDURES 3-8) SUSTAINED LOGIC For situations such as an external channel 'ON' tally lamp, the 1200 Series Console provides a transistor driven logic output for four of the five input channels on each input board. The circuit activates when the channel is turned ‘ON’. This transistor output driver should be used to drive an external relay for interface to other equipment, although it may drive a LED directly through a 1k ohm resistor. WARNING - Maximum current allowed is 50mA.
INSTALLATION PROCEDURES 3-9) PROGRAM & AUDITION OUTPUTS a) LEVELS - balanced out of the console equals 0VU on the meters. Refer to Section 3-16 for details on level calibration. b) OUTPUT IMPEDANCE - The 1200‘s audio outputs are low impedance active balanced design (>100 ohm output impedance) c) MONO MIX OUTPUTS - both Program and Audition outputs have mono mixdowns of the stereo outputs. They do not have level adjust and simply follow the stereo trim levels.
INSTALLATION PROCEDURES 3-10) MONITOR & EARPHONE OUTPUTS The 1200 features unbalanced outputs for Monitor and Earphones . The monitor outputs should connect to an external monitor amplifier that will drive the monitor speakers.The earphone will directly drive high impedance (>600 ohm) headphones, otherwise connect to an external headphone amplifier. The console also features two stereo balanced inputs for monitoring external signals such as air monitors (EXTERNAL MONITOR INPUTS).
INSTALLATION PROCEDURES 3-11, 3-12, 3-13) CUE SYSTEM, TALKBACK SYSTEM, ON-AIR RELAY 3-11) CUE SYSTEM The 1200 handles CUE two ways: 1) AUTOCUE feeds cue audio into the right side of the monitor system while ducking the program audio. 2) &/or connect the mono CUE Output to an external cue amp. a) Mono Cue Output - the Cue output on PIN 7 of connector CN-5 is a mono mix of a stereo cue feed. Output level is about +4dBu and low impedance to drive . speaker.
INSTALLATION PROCEDURES 3-14) MUTING SYSTEM SELECTING A CHANNEL TO MUTE Any channel in the console can be assigned to activate the monitor system‘s muting function. The assigned channels will mute the monitor and cue outputs whenever the channel is turned ON. Install jumpers on the connector illustrated below is to assign appropriate channel to the muting bus. Extra jumpers are provided with the console‘s installation kit.
INSTALLATION PROCEDURES 3-15) MIX MINUS CHANNEL ASSIGNMENT The 1200 Series Console features a Mix Minus system which may be used for telephone or remote feed applications. Audio is sent to this ‘MIX (-)’ bus from all assigned channels in the console. A jumper is used to assign a channel.
INSTALLATION PROCEDURES 3-16) CALIBRATION 3-16a) GENERAL CALIBRATION - The console has gain adjustment trim pots on each input channel, and the output amps. - Line level input channels have trim pots which independently adjust left and right channels. There is approximately 20dB of trim available allowing the module to accomodate input signal levels ranging from - 10dBV (consumer) to +8dBu (professional).
INSTALLATION PROCEDURES 3-16) CALIBRATION (continued) 3-16d) OVERALL RECALIBRATION PROCEDURE IMPORTANT - Overall recalibration is only necessary under unusual circumstances. Recalibrate if all trimpots are moved drastically away from factory settings or when left and right trims are in substantially different positions. This procedure takes some time and concentration. INTERNAL BUS LEVEL - The key to calibration of the 1200 Series console is to set the internal summing bus audio level to -2dBu (.
INSTALLATION PROCEDURES 3-16) CALIBRATION (continued) 3-16d) OVERALL RECALIBRATION PROCEDURE (continued) STEP 3 - RECALIBRATE OUTPUT BOARD With the bus levels held at -2dBu, the Output Board can be calibrated. Only the OUTPUT LEVEL trim pots need adjustment. The VU METER DRIVER trim pots have already been done! a) Select AUD on the Monitor Select Switch b) Adjust the PGM trim pots until the PGM VU meters read “0VU”. DO NOT TOUCH THE VU METER DRIVER TRIM POTS!! ONLY THE OUTPUT LEVEL TRIM POTS.
INSTALLATION PROCEDURES 3-16) CALIBRATION (continued) TRIMPOT PLACEMENT AND USE a) Audio Output Trimpots - The Pgm & Aud output trimpots will adjust gain by roughly 10dB . The trim level is factory set for +4dBm as 0VU on the meters. b) VU Meter Trimpots - The VU meter trimpots adjust from -10dBm to +8dBm for a 0 VU display. The factory calibrates the meters for +4dBm at 0 VU.
INSTALLATION PROCEDURES 3-17) REMOTE SELECT SWITCH The 1200 consoles come with one or two unwired multiple 6 position interlocked switches for use by the customer. The switch is unwired for maximum flexibility. The switches are four pole double throw switches which are ideal for switch stereo balanced audio. The switches are 50,000 operation wiping switches and may be used to switch dry mic level signals stereo lines level signals, and logic, currents to a 50 milliamp maximum.

SPECIFICATIONS & TESTING 5-0) INTRODUCTION The performance test listed this section are: 1) Frequency Response 2) Signal to Noise Ratio 3) Total Harmonic Distortion 4) Crosstalk The purpose of this section of the manual is to provide a general description of the measurement techniques used by Arrakis Systems. Information is also provided regarding variations in test data due to differences in equipment and procedure.
SPECIFICATIONS & TESTING 5-1) FREQUENCY RESPONSE (continued) dB=20[log(V1/V2)] where V2 is the reference level (some arbitrary voltage usually measured at 1kHz) and V1 is the voltage level in question. 5-1c) CONSOLE PERFORMANCE All Arrakis consoles feature “Active Balanced” (electronic balanced) inputs and outputs. That is , there are no transformers or inductors in the signal path. Accordingly, there is no midband ripple at all.
SPECIFICATIONS & TESTING 5-2) SIGNAL TO NOISE RATIO (continued) The many variable factors associated with this test make it difficult to accurately compare SNR specifications between equipment manufacturers. Differences in signal levels, input and output impedences, band limiting filters, test setup and other factors have substantial impact on the test results. Therefor, SNR specs obtained using different test methods cannot be accurately compared.
SPECIFICATIONS & TESTING 5-2) SIGNAL TO NOISE RATIO (continued) IMPORTANT - The IC used for the VCA (SSM2018) has a noise floor that, due to slew rate optimization, increases with frequency above 45kHz. This increase in the noise floor occures outside the audio frequency band and can (should be) ignored. A broadband noise measurement would includes those frequencies above 45kHz hence this type of measurement would be misleading.
SPECIFICATIONS & TESTING 5-4) CROSSTALK 5-4a) DEFINITION Crosstalk is a measure of the amount of signal that bleeds from one audio chain into another. Problems occur when producing two separate programs on a console at the same time or when cueing during programming. If audible crosstalk occurs, then ON AIR integrity can be compromised or a recording can be effected. 5-4b) TEST Apply a test tone to one audio chain, such as Audition Left & Right.
