OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN FRONT PANEL Front Panel Groups The front panel of the EQ1 offers several control and display features. These can be grouped according to Graph 1: Front Panel Elements: Œ - Band Parameters • - Menu Ž - 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).
OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN INTRODUCTION INTRODUCTION Congratulations on purchasing the Weiss Gambit Series EQ1-DYN Digital Equalizer ! The EQ1-DYN is a dynamically controlled equalizer. It has four dynamic bands and three linear bands per channel, each operating at 88.2 or 96 kHz, depending on input sampling frequency (88.2kHz processing with 44.1kHz and 88.2kHz inputs, 96kHz processing with 48kHz and 96kHz inputs).
OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN OPERATION OPERATION The following explanations assume that the equalizer is in power-up mode, i.e. no menu is active. If a menu is active, press the “menu” key repeatedly until the status display appears. Use this value to set the optimal gain for a specific session. Reset it for every session. Status Display Key A Over-Hold Key B Whenever an over is encountered, the boxes to the side of the peak-hold values are marked.
OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN OPERATION 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.
OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN OPERATION Band Parameters What Is A Band? 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 To activate a band and see its detailed parameter values, touch any knob in a band (see Graph 1, Π).
OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN Adjusting Band Parameters Controls To adjust boost, Q/ slope or frequency simply turn the corresponding knob (see Table 1). Peaking-Filter Dynamic-Peaking Shelve-Filter Cut-Filter OPERATION See Graph 1: Front Panel Elements, Ž.
OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN Dynamic If a dynamic peaking-filter has been selected, pressing the “dynamic” key will toggle the Qcontroller of the peaking band between Q- and Threshold-adjustment (this can also be seen in the band display, where either the Q or the threshold value is shown). How to set a dynamic band A good way to start off is by taking some material, and setting the EQ1-DYN so as to correct or pronounce all the bands which you feel need processing.
OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN M/S Mode A 2-channel stereo signal can be transformed from the L/R (left/right) domain into the M/S (mid/side) domain and back without any signal degradation. In the M/S domain, the two channels representing the stereo signal contain information on the Mid (mono) and Side content of the stereo signal. Equalizing in the M/S domain can, for example, just affect vocals or instruments centred in the stereo mix.
OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN Snapshots See Graph 1: Front Panel Elements, •. Snapshots are copies of the EQ1 parameter settings. This allows recalling complete set-ups including all filter parameters and controls settings. Snapshots can be recalled from the front panel or by remote control (e.g. MIDI Program Change). A-B Comparison You can compare two settings by using the two workspaces “A” and “B”. To toggle between the two press the “A-B” key.
OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN OPERATION Loading Graph 8: Backup Display Select “Create 1” to save the current snapshots to bank 1. Select “Restore 1” to overwrite the current snapshots with bank 1 (ditto for bank 2). To load a snapshot dump from sequencer, simply play the dump sequence. The EQ1 will automatically switch into receive mode and display statistics about the snapshots it’s receiving.
OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN Dither The DS1-MK2 v2.0 is able to apply POW-R type dither algorithms to avoid distortion when requantizing from 24bit to 16bit or 20bit output word length (see TECHNICAL DATA for dither specifications). To toggle dither on/off, press key D twice. To see dither status refer to the status display (see Fehler! Verweisquelle konnte nicht gefunden werden. p. Fehler! Textmarke nicht definiert.).
OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN Remote Control All band parameters as well as control settings can be set externally. To see remote control status refer to the status display. OPERATION Software Information Press the “menu” key, then select the “System -> About” option. This displays a screen with all the relevant information on your EQ1 and how to reach us. Have this page ready when you want to report a problem.
