Our top-of-the-line DI is an active direct box that operates with batteries or phantom power. The HotBox provides super-clean, front-end circuitry that delivers the widest frequency response of any direct box on the market. The unusually high input impedance reveals hidden harmonics from guitars with high-output passive pickups. The provided ground-lift switch is useful for eliminating 60 cycle ground loop hum. The inst./line/spkr. switch selects between instrument, line, or speaker level inputs. An LED indicates "on" status.
Frequency Response: 9Hz-200kHz ±3dB, 20Hz-20kHz ±0.05dB Residual Output Noise: -110dB; Maximum Input Level: +15dBu; Rise Time: 1µS Power Requirements: (2) 9V batteries or 48V phantom Battery Life: approximately 150 hours Input Impedance: 10 meg Ohms

Four channels of HotBox performance come in a 1U rack package with built-in power supply. The HotBox Quad provides premium quality DI performance that works equally well in the studio and on the road. For specs, see HotBox Power Requirements: 115/230 VAC 50-60Hz or Phantom Power

This premium direct box converts a line, instrument, or speaker level signal to low impedance balanced mic level. The input is Hi-Z bridging. Features include a 30dB pad switch for selecting between line/instrument or speaker level, a switchable low pass filter to eliminate amplifier noise, and a ground-lift switch on the Lo-Z output. The Director utilizes the TRHL-M transformer.
Input Impedance: 20k Ohms Output Impedance: 150 Ohms Frequency Response: 20Hz-20kHz ±1dB Level Change (input to output): -20dB (pad out), -50dB (pad in)

Four channels of Director DI in a convenient 1U rack package. The MultiDirector is the touring sound standard for passive DIs. Input Impedance: 20k Ohm Output Impedance: 150 Ohm Level Change (input to output): -20dB (padout), -40dB (pad in) Frequency Response: 20Hz-20KHz ±1dB

The ideal direct box for anyone requiring professional quality and durability in an economical package. The IMP 2 converts a line or instrument level unbalanced signal to a low impedance mic level balanced signal. The input is Hi-Z bridging, and the output is provided with a ground-lift switch. Built with Whirlwind's TRHL transformer, you can count on this box to be just as rugged on the inside as it is on the outside.

An economy direct box offering rugged construction while maintaining exceptional sound quality.

Features include:
1/4" In and Through Jacks
Pad switch for connection to "hot" signal sources
Ground Lift switch to help isolate hum and buzz
Metal construction and quality transformer
Superb sound quality

Input Impedance: 20k Ohms
Output Impedance: 150 Ohms
Frequency Response: 20Hz-20kHz ±1dB
Level Change: -20dB (input to output, pad switch set to zero dB)
Pad: 3 position, provides 0dB, -20dB, -40dB additional attenuation

The Whirlwind DIRECT2 combines features found on two of our DIRECTOR® direct boxes in one unit. Each section is comprised of two 1/4" input jacks, one XLR male output connector, a -20dB pad switch and a ground lift switch. Hi/Lo and unbalanced to balanced conversion is accomplished with the same high quality TRHL-M transformer found in the Whirlwind DIRECTOR.Perfect for converting unbalanced signals from stereo keyboards, acoustic guitar preamps, CD and tape players, etc. The input and output grounds are kept isolated from each other so the DIRECT2 can be used with two separate sources without fear of creating ground loop interaction.

Introducing The podMIXai, the big brother to our legendary podMIX

Whirlwind is happy to release the podMIXai, the perfect solution for combining a microphone with your favorite sound track!

The podMIXai is an active mixing device that combines a dynamic microphone with an unbalanced stereo audio source for connection to a single line level input of a sound system. Use it with CD and MP3 players, computer sound card outputs, DJ mixers, etc. along with a microphone in sports arenas, conference rooms, banquet halls, gymnasiums and party houses for paging or announcements over background music. The output is mono balanced line level.

FEATURES

The podMIXai is a small tabletop enclosure with a rugged, ergonomic design for ease of use and easy storage. A wall adapter power supply (PS12AC1A) is included which provides 12 VAC at 1 Amp.

Variable level controls on both the mic and music inputs allow level matching and mixing between the music source and the microphone. The mic input accepts dynamic microphones and can provide up to 60 dB of gain. The music input can boost the signal 20 dB.

On/Off switches for both the mic and music inputs allow convenient muting control of each signal. A bass cut switch is provided on the mic input which can reduce handling and wind noise.

The LED meter has yellow and red LEDs that confirm output level and a green LED indicates that the podMIXai has power . The yellow starts to illuminate when the output signal reaches -10 dB and the red starts at +10 dB and is fully on when the signal reaches +16 dB.

Music signals are input via a single 3.5mm (1/8”) stereo TRS jack which are summed to mono. The microphone input is a balanced female XLR jack and the output is via a balanced male XLR jack.

podMIX

(Back To Top Index)

The podMIX is a passive mixer that combines a microphone with a stereo, line level audio source for connection to a single channel input of a sound system.

Use it to combine your microphone with a CD or MP3 player, computer, DJ mixer, etc., for paging and announcing over background music in banquet halls, sports arenas and party houses.

Accepts the stereo line inputs via 1/8" stereo jack or dual RCA phono jacks and sums them with the microphone into a single balanced mono output. These are wired in parallel and can be used as a loop thru from one to the other.

A variable attenuator on the line input allows level matching and mixing between the music source and the microphone.

Mute switches on both the mic and line inputs provide convenient on / off control of each signal.

Works with both dynamic and condenser microphones and passes phantom power from the output to the mic input.

Features a ground lift switch on the line input to help eliminate hum and buzz.

Can also be used as a high quality DI box.

The HB1XL is a professional quality, passive headphone monitor box.
Description:

A stereo power amp with 50 Watts maximum output is required 
to provide signal to the HB1XL. There are separate, concentric 
volume controls for the left and right channels. Premium quality, 
sealed 2 Watt, audio taper pots provide reliability and precise 
level control. A stereo/mono switch combines left and right channels 
into both earpieces.

DIRECT4

The DIRECT4 combines features found on four of our DIRECTOR^® direct boxes in one unit.
Perfect for converting unbalanced signals from multiple instruments, keys, acoustic guitar preamps, CD and tape players, computer sound cards, etc.
Each section features:

1/4" parallel wired in/out jacks

Ground Lift switch to help eliminate hum and buzz

Filter switch to help reduce amplifier noise and hiss

-20dB pad switch for connection to "hot" input signals

Uses Whirlwind's TRHL-M transformer with metal shield
The input and output grounds of each section are isolated from each other. This allows the DIRECT4 to be used as if it were four completely separate DIs without fear of creating ground loop interaction.
