Like the old EQ1-DS, the EQ1-MK2 supports 44.1, 48, 88.2 and 96kHz sampling frequencies, always using either 88.2 or 96kHz for internal processing. This is responsible for the well-renowned sound of the high resolution units and is the difference to the standard sampling EQ1. Adding to the high resolution processing, the EQ1-MK2 now features an extended parameter set, significantly increasing the number of possible eq settings, as well as a new operational mode for processing stereo signals in the M/S domain (as compared to processing in the L/R domain ­ see chapter M/S Mode, p. 11). The Q now reaches from a near whole-bandwidth-covering 0.20 to a needle-like 650 in 128 steps, allowing everything from subtle sound colouring to notch filter tone removal. The boost varies in 0.1 dB steps from 39dB (for notching) to +18dB. To compensate for the extremely accurate notch filter type, the frequency resolution has been doubled, now running from 14Hz to 21kHz in 12th octave steps plus including special notch frequencies such as 50 and 60 Hz and their harmonics. A further new feature is the settable "shape" parameter for shelving filters, which has the same resolution and a similar effect as the Q parameter for the presence filter type. Combined with the flexibility of seven independent bands per channel, the mastering engineer can now twist the transfer curve to his exact specifications. For exact frequency, boost / cut and Q parameter values please refer to chapter Parameter Table (p. 20).

These can be grouped according to Graph 1: Front Panel Elements: OE - Band Parameters · - Menu Z - Controls · - Snapshots This manual will explain how to operate the EQ1 according to these groups. The Bypass key is discussed separately in chapter EQ Bypass (p. 14). The "gain / data" encoder appears throughout the remainder of this manual and is therefore not explained separately.

This two channel digital equalizer features seven bands per channel, individually configurable as low cut, high cut, low shelving, high shelving or peaking filter. The two channels can be controlled separately or ganged together at the touch of a button. The large CFL LC display and the one-knob-perparameter operation combine speed and ease of use with complete control over audio processing. This and the ability to remote control parameters and snapshots makes the EQ1 the perfect tool for the recording and mastering engineer!

If a menu is active, press the "menu" key repeatedly until the status display appears. Status Display Key A Key B Key C Key D Graph 2: Status Display Use this value to set the optimal gain for a specific session. Reset it for every session. Over-Hold Whenever an over is encountered, the boxes to the side of the peak-hold values are marked. The functions of the over-LED's and the overhold both depend on the NUMBER OF CONSECUTIVE OVER-SAMPLES setting. To adjust this setting, press key B once. Use the "gain/ data" encoder to change the value, then press "menu" to return to the status display. This setting defines the number of consecutive over-samples needed for an over-indication. To indicate every over-sample, enter 1. If another value is entered, you are still able to detect a single over-sample with the peak-hold function. The status display consists of four playing audio signal properties and about the current state of the EQ1. are situated adjacent to the softkeys of the LCD (Graph 2). Channel Status Group groups disinformation The groups to the right Situated adjacent to key A, displays the following information: sampling frequency in kHz: "44.1", " 48", "88.2" or "96" pre-emphasis: "E" appears if pre-emphasis is set (empty if not used) input output channel status data format: "C" for consumer and "P" for professional To change the output channel status data format, press key A and select format type or loop through. Peak Group Situated adjacent to key B, this group contains a peak-hold and an over-hold for each channel. To reset these values press key B twice. Peak-Hold The numeric peak value is measured relative to 0dBFS, where 0dB equals digital full scale.

A full scale signal (0dBFS) will not be treated as over. A signal that triggered an over in a previous processor in the audio chain will therefore not trigger an over in the EQ1 (unless boosted). Remote Group Situated adjacent to key C, displays remote control protocol ("MIDI", "RS 232" or "RS 422"), channel ("1" - "16") and status (on/ off, displayed with check box). For remote control set-up see chapter Remote Control. Snapshot Display Bottom line in the status display. Refer to this for information on current workspace and snapshot. There are two workspaces ("A" and "B") for quick comparison of two equalizer settings. A workspace can be stored to a snapshot for later use. The number of the last recalled snapshot will be displayed. If you change any value after the recall, the " " will change to " " to symbolize that the workspace is not equal to the displayed snapshot anymore. For snapshot handling see chapter Snapshots (p. 12). Dither Icon The dither icon is situated right next to key D (see Graph 2). If dither is off, the icon contains the number "24", the word length of the output signal in bits. Turning dither on will produce arrows above and below the new word length number ("16" or "20"). Additionally, if autoblacking is enabled, the bottom right corner of the icon is inverted. For details on dither refer to chapter Dither (p. 14).

The EQ1 has seven independent bands per channel. A band has the following parameters which can be adjusted separately for each band: 1. Mode 2. Boost 3. Q/ Slope / Shape 4. Frequency Mode specifies the filter type. There are five filter types (low and high cut, low and high shelving and peaking) and a bypass mode. Each band has its own five-LED chain to indicate its active mode (see Graph 3). Graph 3: Mode LEDs To activate a band and see its detailed parameter values, touch any knob in a band (see Graph 1, OE ). The active band's parameter values will be shown in the band display (see Graph 4) replacing the status display, and its LED chain will light up, showing you where to adjust the parameter values. Graph 4: Band Display Depending on the setting of "Auto Switchback From Band To Status Display", this display will hold forever or disappear again after having released the knob. To change the "Auto Switchback From Band To Status Display" setting, press the "menu" key, then select "Controls" with key B. The value can now be changed with key B. High Shelving Low Shelving Peaking High Cut Low Cut Range The parameters' range is independent of the mode and is listed at page 20.
