20、hannel, third-octave equaliser that offers state-of-the-art audio performance in a remote controlable, tamper-proof, cost effective package. The two channels may either be used independently or linked for stereo use. To further extend the flexibility of the equaliser, the unit also incorporates vari

21、able frequency low and high-pass filters, two notch filters with variable frequency and depth and overall gain adjustment on each channel. Being the slave derivative of the Klark Teknik model DN3600, the DN3601 front panel features only twin signal strength meters, clip LEDs, an LED numerical displa

22、y and a power switch. The unit can be controlled by a master DN3600 unit or by a suitably equipped computer or other MIDI control device. Up to 64 DN3601 units (or mixed DN3600s and DN3601s) may be linked in a single MIDI loop via the Pro MIDI Interface on the rear panel. The DN3601 may store up to

23、66 equaliser programs in its own, internal memory and can then take full advantage of the extensive user interface of the controling device. A 16-pin connector is provided on the DN3600 for use in conjunction with the DN60 Real Time Spectrum Analyser enabling room analysis and equalisation to be acc

24、omplished automatically. An extensive equalisation system can be created with central, user friendly control. Slave units may be addressed individually or globally by the master, and will also respond to standard MIDI program change commands. The proprietary analogue filters are based around the Kla

25、rk Teknik “MELT” hybrid filter circuits which offer far greater headroom and dynamic range than is possible using 18-bit linear, digital systems. Benefiting from revised circuitry, these filters are exceptionally reliable and offer greater stability than discrete designs. They are also relatively im

26、mune to electromagnetic interference, unlike coil-based filters. Separate supply rails are used for the digital and analogue circuitry which, in combination with rigorous internal screening, ensures the cleanest possible audio signal path. In order to provide maximum operational flexibility, the sys

27、tem includes a switchable Q mode. The Low Q setting (Q:360) provides an accurate emulation of the industry-standard DN360 equaliser. In High Q mode (Q:27), the performance emulates the DN27. To maintain the optimum signal to noise ratio and headroom at all equaliser settings, the gain control acts o

28、n the equaliser sections themselves rather than being a simple pre or post-equalisation gain stage. Additionally, an Auto gain mode is included in the system which automatically scales the gain of the individual equaliser bands as cut or boost is applied to reduce the risk of accidental clipping and

29、 to maintain a safe working headroom. Both the input and output circuitry is electronically balanced with a nominal operating level of +4dBu. The output circuitry is based on the Midas XL3 output stage, giving exceptionally high drive capability. A transformer option is available for both inputs and

30、 outputs. 9 Installation The inputs and outputs are fully balanced on XLR connectors and are wired conventionally with pin 1 as ground. Because the system is fully floating, either pin 2 or pin 3 can be designated as hot so long as the same protocol is adhered to for both the input and the output co

31、nnectors. The DN3601 is designed for use in both fixed and mobile installations where it can be mounted in a conventional 19 inch rack occupying just 2U of height. In mobile situations where rough handling is a possibility, it is advisable to support the rear of the unit to prevent undue stress bein

32、g placed on the front panel. Ensure that the unit has sufficient ventilation and that it is not placed directly over any device which runs hot such as a power amplifier or console power supply. 10 Instrument Familiarisation Front panel functions NUMERIC WINDOW: Displays the address number of the Sla

33、ve and flashes on and off when the unit is being addressed by an external controler, such as a DN3600. METERS: Separate 10-segment bargraph level meters monitor the signal level in channels A and B over the range -12dB to +15dB. The Clip warning LED monitors seven different points within the circuit

34、ry of the DN3601 and flashes if the level at any point comes within 2dB of clipping. POWER SWITCH: Switches the unit on and off. When the unit is off, there is a hard relay bypass which connects the input signal directly to the output. Rear Panel Functions Balanced Input XLR Sockets Balanced Output

35、XLR Sockets Pro MIDI XLR Connectors: These follow the same wiring convention as conventional MIDI DIN sockets. These are used for performing system exclusive data transfer and for linking multiple units in a master/slave configuration. See service section for wiring convention. Voltage Selector Swit

36、ch: selects between 120V and 240V operation. IEC Mains Socket. 11 MASTER/SLAVE OPERATION The Klark Teknik Pro MIDI Master/Slave system allows up to 65 DN3601 and DN3600 units to be operated, either individually or together, from the front panel of a single DN3600 or a siutably equiped computer. The

37、system is simple to connect, simple to operate and protects itself from the dangers of unreliable power supply and damaged connections. Once programmed, the equaliser program memories resident in the DN3601 Slaves may be selected via ordinary MIDI program change commands without the need for a DN360

38、0 master unit. This provides an economical way of managing a large installation as the slave system is both cost effective and secure from inadvertent tampering. Connections. For remote control of all parameters, any DN3601, DN3600 and computer devices must be linked in a closed loop via their Pro M

39、IDI interfaces - MIDI OUT to MIDI IN. Master/Slave configuration is automatic when two or more DN3600 and/or DN3601 units linked in this way. Remote control is via system exclusive messages. Note: The loop must be closed. Each MIDI OUT must be connected to the next MIDI IN. If MIDI program change me

40、ssages from some other device are to be injected onto the Klark Teknik loop, this must be done via a MIDI MERGE unit. Master SlaveSlave Slaves Optional MIDI Merge 12 Any DN3600 in the loop can be designated as the Master by entering the Slaves sub menu (press Utilities, More., Slaves on the DN3600).

41、 The other DN3601 and DN3600 units in the loop will automatically configure themselves as slaves, with the first being number 1, the second being number 2 and so on. Each slave will display its number on its own front panel LED display. A maximum of 64 units may be connected in this way (65 includin

42、g the Master). To address an individual DN3601 Slave, enter the Slaves sub-menu of the Master DN3600 unit. The slave address number can now be changed using the FREQ or LEVEL rotary controls. Press the Slaves soft key a second time to initiate control of the selected device. All the controls and dis

43、play modes now affect only the selected DN3601 Slave unit. The number of the selected Slave is displayed as highlighted text at the top of the LCD screen. The address number on the front panel LED of the DN3601 will flash on and off. Only the Slaves and Lock sub menus relate to the Master unit. To a

44、ddress another slave, enter the Slaves sub menu and select a new slave number. To address all the Slaves in the loop, enter the Slaves sub menu and select SELECT ALL. All functions and controls now affect all units including the Master. For example, performing an Auto EQ function now will adjust all

45、 the units in the loop to equalise the spectrum of a DN60 connected to the master. To return to normal operation, ie adjustment of the Master itself, the Slaves selection must be returned to “STAND ALONE”. The slave units will retain their current settings until changed. All controls and display mod

46、es now affect only the Master unit. Note: A MIDI loop can only have one Master. Initiation of another master by entering its Slaves menu will cancel the original master and renumber the loop. Program Changes. DN3601 Slaves (and DN3600s) will respond to standard MIDI program change messages without t

47、he need for a DN3600 master unit or a closed loop. Just feed the MIDI signals into the MIDI IN socket. All MIDI messages will be copied through to the MIDI OUT socket. A system such as this offers benefits of reduced cost and inherent tamper proof security. As well as real time operation from a cent

48、ral control position, a network of equalisers may be loaded with the memories necessary for various tasks and then, with the master unit removed, will respond only to program changes. 13 DETAILS OF OPERATION Being a description of the features and functions accessible via a DN3600 master unit with v
