3. third harmonic The level of distortion is such that it reaches 6 5 at digital zero It is 0 3 at 4dbm at the analog output which is 20 dB below digital zero The LEVEL METER is a 16 segment peak reading meter and is referenced to the A D convertor Ana log head room is such that there is 6 db of analog head room above the level that is digital zero This is to allow up to 6db of limiting before the A D convertor An over on the meter is a digital over but not necessarily an indicator of analog clipping There is 6db of analog headroom above digital 0 with out the limiter engaged There is also aclip indicator on each channel This is a small red light in the upper left hand corner of the channel This indicator shows an input or pre amp overload The level meter is an analog device that is feed from the A D convertor input The LIMITER is for peak overload protection and is in front of the A D convertor in the signal path The level meter is post limiter There is an indicator on the channel next to the limiter button that lights when ever limiter action is taking place The limiter is enabled by pushing the LMT button down The signal structure is such that the input channel can provide 6 dB more level that the A D convertor needs This headroom is for the operation of the peak limiter The limiter will bring the level down thus protecting the A D convertor from overload The ANALOG INSERT POINT is a 1 4 phone jack and is wired as tip sen
4. WER SWITCH turns on or off the 48V power for phantom power and is active when the switch is pressed in The LINE MIC SWITCH selects between the line and mic inputs for the channel When the switch is out the mic input is selected and when it is pressed in the line input is selected The PHASE SWITCH provides phase reversal for the channel When the switch is out the channel operation is with normal phase When the switch is pressed in the phase is reversed This is referenced to pin 2 signal on the mic input and tip signal on the line input The mic connector is an XLR where as the line input connector is a 1 4 TRS connector The LOW CUT FILTER is engaged when the switch is pushed in with a cutoff frequency of approx 80 Hz The filter is intended to be used in eliminating rumble undesired low frequency content and mud while keeping the effect on the desired audio to a minimum The slope reaches 12 dB pre octave When the switch is out the filter in not engaged and the low frequency response is to 3Hz When the STEREO BUS ASSIGNMENT SWITCH is pushed in the channel is assigned to the stereo bus When the switch is out the channel is not assigned to the bus The channel outputs are always assigned to the 8 channel outputs The FAT AMPLIFIER is enabled when the switch is active pressed in The fat amplifier is used to provide a different sound by inducing tube like distortions This distortion content is almost all second harmonic with some
5. d and ring return This insert point is unbalanced and has a maximum signal level of 24 dbm 8 CHANNEL DIGITAL SECTION The SAMPLE RATE SELECTION SWITCH allows the selection of 1 of 4 sample rates from 44 1K to 96K or the selection of a word clock source The WC source is the same for both the stereo and 8 channel sections The STEREO BUS can be assigned to digital channels 7 and 8 This is to allow a mix to be recorded by a recorder on channels 788 of the 8 channel output The assignment takes place by pushing the bus 7 amp 8 switch in When this is done the normal connections from input channels 7 and 8 are disconnected The limiter on the digital stereo module is still used to prevent digital overload on the bus signal The DITHER CONTROL provides dithering to different bit levels This source is unique to CRANE SONG and is generated by analog means The audio signal and the dither source are mixed together going into the A D convertor This is the best place to create dithering The switch has many selections There are 16 and 20 bit choices and some options for play and experimentation DSP ANALOG TAPE EMULATION is adjustable by channel The tape emulation feature provides a means to have analog tape sound in Spider s digital outputs By selecting the channel the LEDs around the process knob will light showing the current level of the process By turning the process knob the control becomes active and allows the setting a new level A

7. l is still adjusted by channel This is because the DSP is post A D convertor and we are reassigning the analog routing not the digital routing The limiters are for peak control Ifthe limit light is on a lot they are being used more than intended Boot up takes approx 10 seconas this is to allow the A D convertors to reach their highest accuracy level before use Spider contains 3 DSP parts for 300 mips of computing power 1 5Mbytes of memory and 17 micro processors But you will not see General Fault trying to protect you STANDARD HIGH GAIN MODE HI LEVEL INPUT MODE E z n TOP AND FRONT VIEW OF INPUT MODULE LEVEL METER SEND TO INPUT MODULE ANALOG TAPE LEVEL AUDIO INPUT FROM CHANNEL OUTPUT LIMITER LIMITER CONTROL FROM CHANNEL AD ANALOG CONVERTOR 200 MIPS 8 CHANNEL OUTPUT DITHER DSP AES GENERATOR ADAT TDIF ONE OF EIGHT CHANNELS SHOWEN 8 CHANNEL A D DSP AND OUTPUT SUMMING AMP TRS INSERT POINT LEVEL METER STEREO BUS INPUT lt AMP LIMITER STEREO FADER ANALOG TAPE LEVEL ANALOG STEREO OUTPUT DITHER STEREO AES STEREO LIMITER TO A ny AD DSP SPDIF TOSLINK SUMMING AMP TRS INSERT POINT STEREO BUS f INPUT lt AMP LIMITER STEREO FADER LEVEL METER STEREO MASTER A D AND DSP LEVEL METER METER SIGNAL 8 CHANNEL FROM 8 CHANNEL A D

9. set of jumpers on the top of the unit in each channel to change the sensitivity of the line input The standard mode will allow up to a 18 dom onthe input with the 6db gain setting providing 6db of gain In the padded mode there is a 20 db pad inserted on this input The hi gain mode which is the standard mode will work in most cases and is recommended The insert pointis a 1 4 TRS with tip being the send and the ring being the return Ifyou want to leave this normal and also have the analog output available connect the tip and ring together and use this as you signal output The stereo master back has a left and right insert jack that works like the channel insert point It also has an accessory connector to allow the analog sections of up to 3 spiders to be tied together and the power connector The stereo digital sections back panel has an XLR connector for AES output a RCA connector for S PDIF output a optical connector for stereo optical output and 2 word clock connectors The WC connec tors are BNC connectors for WC in and WC out This provides the WC connection for both the stereo and 8 channel outputs The 8 channel digital output connectors depends on the type of interface For AES outputs it has 4 XLR connectors and the ADAT interface it has 2 optical outputs and supports SMUX to 96K Things to be aware of When the stereo bus is assigned to digital outs 7 and 8 Be aware that the Stereo bus limiter still ap plies but the DSP contro
