RADIAL DI BOXES

12 Produkte

A series of passive and active DI (Direct Injection) boxes from Radial designed for live performances to connect unbalanced instruments or DJ consoles into the balanced input of a mixing desk or PA system.


BT-PRO V2 Active, stereo, Bluetooth input

BT-Pro V2 is an active Bluetooth-enabled direct box that connects wirelessly to smartphones, tablets, and other mobile devices, providing a pair of balanced analogue audio outputs to feed a PA system. The device wirelessly pairs over Bluetooth, eliminating the need to search for adaptor cables and providing you with the freedom to move around while staying connected. The Bluetooth audio source can be up to 100ft away from the DI box.

Bluetooth 5.0 protocol is employed, allowing the BT-Pro V2 to be used for playback in live or critical listening environments. While the BT-Pro V2 is designed to last with a 14 gauge steel outer shell and high durability connectors and controls, it also has an enhanced reception range thanks to the plastic injection-moulded insert, which allows wireless signals to pass through unimpeded. Balanced 3-pin XLR outputs are provided for connection to external audio equipment, with a single level control to allow for volume adjustments. A headphone output by way of 3.5mm jack connection is provided for test purposes, and a mono switch allows channel the user to switch to a mono summed output when reduced channel requirements when needed.

Each BT-Pro V2 has a unique identifier, allowing multiple units to be used within the same building. BT-Pro V2 can also be powered via 48V phantom from a mixing console.

Frequency response: 20Hz - 20kHz. Dynamic range: 90dB. Output impedance: 150ohms. Signal to noise: 90dB. Dimensions (LxWxD): 84 x 127 x 51mm. Weight: 500g


J48 Active, mono

Radial J48 direct box is a single-channel, phantom-powered active DI that has been optimized to handle extreme transients whilst using only the 5mA of available current from typical 48V phantom power. Using a digital switch-mode power supply, J48 steps up the internal rail voltage to 9-Volts.

Designed for use in live concert touring or professional recording studio applications, the DI box features switching for ground, 80Hz low cut, polarity, 15dB pad, and merge that effectively turns the DI box into a passive mixer with summed mono output. Input is by way of 6.35mm jack connection, thru connection is also 6.35mm jack, and the 600ohm balanced output is by way of 3-pin XLR connector. A momentary LED flashes only once to signify the presence of phantom-power, thus saving power.

Frequency response: 20Hz - 20kHz. Dynamic range: 109dB. Output impedance: 200ohms. Maximum input: +10dBu. Dimensions (LxWxD): 84 x 127 x 48mm. Weight: 720g


JDI Passive, mono

Radial JDI is a single channel, passive direct box that features a Jensen transformer to isolate the signal and reject noise, while having a 'wide frequency response' and 'virtually zero distortion' of all types.

JDI employs a Jensen JT-DB-EPC audio transformer to produce a flat frequency response from 10Hz up to 40kHz, while minimizing phase and harmonic distortion and isolating the signal to prevent hum and buzz from ground loops. When connected to high output sources such as active basses or electronic instruments, JDI saturates instead of clipping, and therefore produces a warm sounding bessel curve that is said to emulate some of the most sought-after vintage equipment.

Switching includes 15dB pad, merge - to turn the input and thru jacks into a passive mixer and sum to mono; 180degree polarity reverse, ground lift, and speaker - which inserts a -30dB pad and speaker emulation. The casing is manufactured from 14-gauge steel to handle touring environments.

Frequency response: 20Hz - 20kHz, +/- 0.2dB. Dynamic range: 135dB. Output impedance: 150ohms, balanced. Maximum input: +21dBu. Dimensions (LxWxD): 165 x 102 x 76mm. Weight: 703g


JDI STEREO Passive, stereo

Radial JDI Stereo shares the audio specifications of Radial JDI, however it is dual mono and therefore has twice the input and output channel counts. JDI Stereo does not have switching for polarity, merge, nor speaker emulation.

Frequency response: 20Hz - 20kHz, +/- 0.2dB. Dynamic range: 135dB. Output impedance: 150ohms, balanced. Maximum input: +21dBu. Dimensions (LxWxD): 127 x 84.1 x 45.5mm. Weight: 703g


PRO48 Active, mono

Radial Pro48 is a 48V phantom powered, active direct box designed specifically for higher output instruments like active basses and acoustics guitars. The DI box features an internal switching power supply that increases headroom and has the benefit of less distortion whilst yielding a smooth and linear response that extends from 20Hz to well above 100kHz.

PRO48 has a 6.35mm jack input, 6.35mm jack thru link, balanced 3-pin XLR output, a ground lift switch, and -15dB pad switch. A red LED signifies the presence of phantom power.

Frequency response: 20Hz - 20kHz, +/- 0.2dB. Dynamic range: 99dB. Output impedance: 175ohms, balanced. Maximum input: +9dBu. Dimensions (LxWxD): 108 x 70 x 44mm. Weight: 540g


PROAV2 Passive, stereo

Radial ProAV2 is a dual channel passive direct box designed specifically for the audio-video professional where ‘Swiss Army knife’ connectivity is required to meet on-the-fly demands of AV rentals and installations. ProAV2 has been designed for use with portable computers, CD players, iPods and other sound sources that must interface to PA systems alongside microphone lines.

A custom-wound transformer is employed to convert the impedance and balance the line while providing common-mode rejection. The transformer also eliminates noise associated with ground loops. To further reduce susceptibility to noise, the transformer is encapsulated in a nickel metal can, thus preventing RF and electromagnetic induction. Input connectivity includes dual RCA (phono), dual 6.35mm jack and a single 3.5mm jack for high-impedance instrument and -10dB consumer line-level devices. All inputs may be used as thru-puts and are auto merged to mono to reduce cable infrastructure and audio channel requirements. The output is 3-pin XLR for direct interconnect to mixing console mic inputs. Switching includes input ground lift, -10dB pad, and global output ground lift.

ProAV2 is constructed with 14 gauge steel for durability, while it’s book-end enclosure is designed to protect the switches and connectors from damage.

Frequency response: 20Hz - 18kHz, +/- 0.2dB. Dynamic range: 128dB. Output impedance: 150ohms, balanced. Maximum input: +18dB. Dimensions (LxWxD): 102 x 76 x 165mm. Weight: 820g


PRODI Passive, mono

Radial ProDI is an ultra-compact passive direct box that has been specifically developed to allow regional sound companies and project studios to have a more affordable solution. ProDI features a custom-made transformer that is able to handle high levels without saturation. This high-performance transformer has a linear frequency response from 20Hz to 18kHz, making it a popular combination with electronic musical instruments, bass or acoustic guitar, and audio equipment. ProDI also features a -15dB pad for high output sources, and ground lift switch to troubleshoot noise from ground loops.

Both input and thru connections are by way of 6.35mm jack, and the output is by way of balanced 3-pin XLR connector. Switching includes a -15dB pad and a ground lift switch.

Frequency response: 20Hz - 18kHz, +/- 0.2dB. Dynamic range: 128dB. Output impedance: 150ohms, balanced. Maximum input: +18dB. Dimensions (LxWxD): 108 x 70 x 44mm. Weight: 540g


PROD2 Passive, stereo

ProD2 is essentially two ProDI’s in one compact enclosure. It has been designed for use with stereo keyboards, DJ equipment and consumer hi-fi systems. The single ground lift switch is global across both output channels whilst the -15dB pad switches are channel independent.

Frequency response: 20Hz - 18kHz, +/- 0.2dB. Dynamic range: 128dB. Output impedance: 150ohms, balanced. Maximum input: +18dB. Dimensions (LxWxD): 127 x 84.1 x 45.5mm. Weight: 540g


PROD8 Passive, 8-channel

Radial ProD8 is a 19-inch rack mountable, 8-channel passive direct box designed specifically for keyboard systems in pro touring environments. Each channel features dual 6.35mm jack inputs that are pre-merged using a resistive circuit. The dual inputs may be used to sum a stereo signal to mono or for redundant back-up systems in case of equipment failure. A built in effects loop uses a 6.35mm TRS insert jack allowing the dual inputs on each channel to share an external effects device. Local monitoring for each channel is provided via the parallel thru-put connector - also on 6.35mm jack.

ProD8 is equipped with eight custom wound Radial transformers, each encapsulated inside a nickel mu-metal (a nickel–iron soft ferromagnetic alloy) can to reduce noise and distortion caused by outside magnetic fields. To accommodate high output instruments and line level equipment, a -15dB pad is provided on the input panel. Balanced 3-pin XLR outputs are equipped with polarity reverse, ground lift and chassis ground switches to help interfacing with stage and studio environments. For added flexibility, reversible rack ears allow either panel to face front.

Frequency response: 20Hz - 18.5kHz, +/- 0.2dB. Dynamic range: 128dB. Output impedance: 150ohms, balanced. Maximum input: +18dB. Dimensions (LxWxD): 483 x 158.75 x 44.5mm. Weight: 3.26kg


STAGEBUG SB-5 Passive, stereo

StageBug SB-5 is a stereo direct box that has been specifically designed to interface a laptop, tablet, smart phone or music player with professional audio systems. The DI box features a captive cable that is terminated with a standard TRS 3.5mm jack connector along with a integrated cable cleat for easy storage. SB-5 allows the user to reduce noise, enable long cable runs and improve the sound quality by properly matching the impedance and optimizing the signal level of your mobile device to work with a PA system.

A pad switch reduced the input sensitivity by 15dB, whilst a ground lift switch aids in the reduction of ground noise and buzzing. SB-5 is passive and therefore requires no powering.

Frequency response: 20Hz - 20kHz, +/- 1dB. Dynamic range: 100dB. Output impedance: 2.8kohms, balanced. Maximum input: +20dB. Dimensions (LxWxD): 114 x 47 x 34mm. Weight: 250g


TRIM-TWO Passive, stereo

Designed for buffered sounds such as laptops, tablets, DJ mixers and keyboards, Radial Trim-Two is a passive direct box that incorporates a front-panel level control for ‘on-the-fly’ volume adjustments. This is particularly helpful for users that employ laptop computers on stage or for presentations where quick level adjustments are often compromised by software, mouse actions or the need to use a qwerty keyboard.

Trim-Two features Radial's I-beam construction to protect the inner working from being torqued, along with a book-end convert that creates a safety zone around the switches, volume control and connectors. Two custom-made Eclipse transformers, positioned insider the 14-gauge steel casing, lower the impedance to reduce susceptibility to noise and perform the signal balancing to permit long cable runs up to 100m.

Other features include a ground lift switch that work with the isolation transformers to further eliminate ground loops, and a stereo-to-mono summing circuit that mixes the left-right inputs to dual mono at the balanced 3-pin XLR output stage. Inputs are by way of dual RCA (phono) and dual 6.35mm jack connectors. A stereo 3.5mm TRS input allows a third method of input.

Frequency response: 20Hz - 20kHz. Dynamic range: Greater than 100dB. Output impedance: 2.8kohms, balanced. Maximum input: +20dB. Dimensions (LxWxD): 84 x 127 x 48mm. Weight: 700g


USB-PRO Active, stereo

Radial USB-Pro is a plug and play, 24-bit digital to analogue audio converter and direct box in a compact and road rugged chassis. A built in preamp allows the user to adjust the output level from mic-level to line-level, and enables the USB-Pro to connect directly to mixing consoles, power amplifiers and self-powered speakers alike. USB-Pro derives power from the USB connection and automatically configures the sampling rate and bit depth without the need for special drivers. USB-Pro can also be system testing and for transferring digital audio files to analogue for processing.

USB input is by way of type-B connection, which is also used for powering. A single green LED signifies power on status. A rotary controller allows the user to adjust the global output level from both left and right 3-pin XLR connections and 3.5mm headphone jack output. A switch allows the signal to be mono summed, with an LED to signify when active. A ground lift switch lifts pin-1 on both output XLRs to reduce hum and buzzing. Finally, two switches on the side of the DI box can be employed to insert isolation transformers into the audio signal path to help eliminate hum and buzz caused by ground loops.

Frequency response: 5Hz - 40kHz. Dynamic range: Greater than 90dB. Output impedance: 250ohms, nominal. Maximum output: +8dBu. Sampling rate: 44.1/48/96kHz. Dimensions (LxWxD): 127 x 84 x 48mm. Weight: 680g
