4. סעטאַפּ און ייַנמאָנטירונג
4.1 אַנפּאַקינג
Carefully remove the dbx 215s from its packaging. Retain the original packaging materials for future transport or storage. Inspect the unit for any signs of damage that may have occurred during shipping. If damage is found, contact your dealer immediately.
4.2 געשטעל מאַונטינג
The dbx 215s is designed for standard 19-inch rack mounting. It occupies 1U (one rack unit) of space. Ensure adequate ventilation space around the unit, especially if mounting other heat-generating equipment nearby.
- Align the mounting holes on the equalizer with the holes on your equipment rack.
- Secure the unit using appropriate rack screws (not included).
4.3 אַודיאָ קאַנעקשאַנז
The 215s offers both XLR and ¼” TRS balanced connections. For optimal performance and noise rejection, balanced connections are recommended.
- אַרייַנשרייַב קשר: Connect the output of your mixer, preamplifier, or other audio source to the INPUT of Channel 1 and/or Channel 2 on the dbx 215s using XLR or ¼” TRS cables.
- רעזולטאַט קשר: Connect the OUTPUT of Channel 1 and/or Channel 2 on the dbx 215s to the input of your amplifier, powered speakers, or next device in the signal chain using XLR or ¼” TRS cables.
- Ensure all connections are secure and correctly wired (Pin 2 Hot for XLR).
4.4 מאַכט קאַנעקשאַן
- Before connecting power, ensure all audio connections are made and the unit's power switch (if present, though typically on the front for dbx EQs, this model has no explicit power switch on front, it's always on when plugged in) is in the OFF position or that the unit is not yet plugged into the AC outlet.
- Connect the supplied AC power cord to the IEC inlet on the rear panel of the dbx 215s.
- Plug the other end of the power cord into a suitable AC power outlet. The unit operates on 100-240V~, 50/60Hz.
5. אָפּעראַציע
5.1 פּאַוערינג אויף / אַוועק
The dbx 215s does not feature a dedicated power switch on the front panel. The unit powers on automatically when connected to an active AC power source. To power off, disconnect the AC power cord from the wall outlet or the unit's rear panel.
5.2 Basic Equalization
The 215s allows you to adjust the frequency response of your audio signal. Each of the 15 sliders corresponds to a specific frequency band. Moving a slider up boosts that frequency, while moving it down cuts that frequency.
- אַרייַנשרייַב געווינס: Use the Input Gain knob to set the overall input level. Aim for the green LEDs on the output meter to light consistently, with occasional yellow flashes, avoiding red clipping indicators.
- Range Switch (±6 dB / ±12 dB): Select the desired boost/cut range. The ±6 dB setting provides finer control, while ±12 dB offers a wider range of adjustment.
- בייפּאַס סוויטש: Press this button to bypass the equalizer's processing. This allows for quick A/B comparisons between the processed and unprocessed signal. The LED above the switch indicates its status (typically lit when active, off when bypassed).
- אָפטקייט סליידערס: Adjust individual frequency bands to shape your sound.
- Low Frequencies (20Hz - 160Hz): Affect bass and sub-bass. Boosting can add warmth or punch; cutting can reduce muddiness.
- Mid Frequencies (250Hz - 4kHz): Crucial for vocals and instruments. Adjusting these can affect clarity, presence, or harshness.
- High Frequencies (6.3kHz - 16kHz): Control treble and air. Boosting can add sparkle; cutting can reduce hiss or harshness.
- Output Level Meter: Monitor the output signal level. Ensure the signal is strong enough without clipping (red LED).
When equalizing, it is generally recommended to make cuts rather than boosts to avoid introducing noise or distortion. However, the 215s is designed for high fidelity, allowing for effective boosts when necessary.
6. וישאַלט
6.1 רייניקונג
To clean the unit, use a soft, dry cloth. Do not use abrasive cleaners, waxes, or solvents. Ensure the unit is powered off and disconnected from the AC outlet before cleaning.
6.2 קאָריק פאַרבייַט
If the unit fails to power on, the fuse may need replacement. The fuse holder is located on the rear panel near the AC power inlet.
- דיסקאַנעקט די מאַכט שנור פון די אַק ווענטיל.
- Locate the fuse holder on the rear panel.
- Carefully pry open or twist the fuse holder cap (depending on type).
- Remove the old fuse and replace it with a new fuse of the exact same type and rating as specified on the unit's rear panel (e.g., T500mAL 250V). Using an incorrect fuse can damage the unit or pose a fire hazard.
- Securely close the fuse holder.

| קיין אַודיאָ רעזולטאַט. | Incorrect cable connections; Bypass switch engaged; Input gain too low; Source device not sending signal. | Verify all audio cables are correctly connected to inputs and outputs. Ensure bypass switch is disengaged (LED off). Increase input gain. Check if the source device is functioning and sending audio. |
| Hum or buzz in audio. | Ground loop; Unbalanced cables in a balanced system; Faulty cables. | Ensure all equipment is properly grounded. Try using balanced XLR or TRS cables. If hum persists, a ground loop isolator may be necessary. Test with different cables. |
| פאַרקרימט אַודיאָ. | Input gain too high (clipping); Output level too high; Faulty component. | Reduce input gain until red clipping LEDs no longer illuminate. Lower the output level of the 215s or the next device in the chain. If distortion persists, contact service. |
| Sliders feel loose or unresponsive. | Normal wear; Internal issue. | The sliders on dbx units are known for their solid feel. If they feel unusually loose or do not affect the sound, contact service. |
