The BEHRINGER V-TONE BASS BDI21 is a high-quality bass driver designed to cater to the diverse and wide-ranging needs of bassists. This versatile device integrates tube emulation, delivering the authentic sound and response of a miked bass tube amp. Its comprehensive control set, including a 2-band EQ with a presence control and a dedicated drive control, allows users to craft a vast array of bass tones, from vintage warmth to modern punch. Beyond its tone-shaping capabilities, the BDI21 also functions as a standard, ultra-transparent direct injection (DI) box when operating in bypass mode.
A DI box, like the BDI21, serves the crucial function of converting an unbalanced, high-impedance signal (typical of a bass guitar) into a balanced, mic-level signal suitable for direct connection to a mixing console. This makes the BDI21 an ideal tool for various scenarios, whether on stage, in the recording studio, during rehearsals, or even for warm-up sessions, offering a simple yet effective setup for achieving great bass tone.
The core of the BDI21's functionality revolves around its tone-shaping controls. The DRIVE control allows users to adjust the overall amount of gain and overdrive, mimicking the effect of pushing the output section of a tube amp. This provides a rich palette of distortion and sustain. The 2-band EQ consists of TREBLE and BASS controls. The TREBLE control governs the high-frequency range of the signal, offering a +/-12 dB adjustment to either brighten or soften the tone. Similarly, the BASS control enables users to boost or cut the low-frequency range, providing +/-12 dB of adjustment for adding warmth or tightening the bottom end.
A unique feature is the PRESENCE control, which boosts the upper harmonic content of the signal. This results in a smoother high end and adds more attack to the bass sound, enhancing clarity and definition. The overall output volume of the BDI21 is managed by the LEVEL control.
The integrated tube emulation is a key aspect of the BDI21's sound. The BLEND control allows users to adjust the amount of this tube emulation, effectively mixing the emulated tube sound with the dry signal. This circuitry is designed to provide the authentic tube sound of a miked bass tube amp, offering warmth, compression, and harmonic richness.
For connectivity, the BDI21 features a 1/4" TS INPUT connector for plugging in a bass guitar or other instruments. For balanced output to a mixing console, it provides a BAL OUT XLR connector, which is a mic-level output. A high-quality, balanced XLR cable is recommended for this connection. Additionally, an unbalanced 1/4" TS OUT connector sends the signal to a bass amp, allowing for simultaneous monitoring or further signal processing.
The device is equipped with a footswitch that serves to activate or deactivate all the tone functions, including EQ, DRIVE, and tube emulation. When the effect is deactivated, the BDI21 operates solely as a standard, transparent DI box. An LED indicator illuminates when the effect is active, providing clear visual feedback.
The BDI21 is designed for ease of use in various applications. It can be used directly with a bass guitar or other instruments like acoustic/electric guitars or keyboards to create new sounds and enhance music. Users should ensure that the input level is not too high to prevent overloading the unit.
For live and studio applications, the balanced XLR BAL OUT can be connected directly to a mic input on a mixing console. It's important to manage the gain control of the respective channel on the mixer to avoid overloading the input.
The BDI21 can also be utilized without an instrument as an outboard processor. By connecting it to an insert or an effect path (aux send/return) of a mixing console, it can affect the signal of a particular channel, enhancing existing tracks during mixdown.
A practical feature is the GND LIFT switch. When activated, this switch disconnects the ground connection between the input and output. Depending on the grounding of the connected equipment, this can effectively eliminate hum or ground loops, ensuring a cleaner signal.
The BDI21 is powered either by a standard 9 V alkaline battery or an optional 9 V DC power supply (not included). The battery compartment is located on the bottom of the unit, making battery replacement straightforward.
To prolong battery life, it is crucial to always disconnect the input cable when the driver is not in use, as the BDI21 does not have a dedicated on/off switch; it powers on as soon as a plug is inserted into the INPUT.
When using an external power supply, it is imperative to use only a DC power supply with a 9 V regulated output, a minimum of 50 mA, and a 2 mm female plug with a negative center. Failure to adhere to these specifications may damage the unit and void the warranty.
The device is designed for durability and reliability. However, users should avoid removing the cover, as there are no user-serviceable parts inside. Servicing should be referred to qualified personnel. Additionally, the equipment should not be exposed to rain or moisture to prevent damage.
The serial number of the BDI21 is conveniently located on the bottom of the unit for easy reference, which is useful for warranty claims or product registration.
