Studio Headphone Amplifiers

Notes: The ART HeadAmp4Pro could be the most fully featured ultra compact headphone amplifier in its price point on the market today.

Packing as many features as possible into the small format chassis, the HeadAmp4Pro has five stereo headphone outs, each with their own volume control. A separate footswitchable XLR input (with phantom power) allows instant talkback to any one, or all of the connected headphones. Input matrix allows the listener to audition any or all auxiliary inputs for maximum versatility.

Although designed for home and project studio, the HeadAmp4Pro may easily be the ideal solution for teaching stations and conferencing communication networks.

Notes: An articulate headphone mix can make all the difference in the outcome of a recording session. The 6-channel POWERPLAY HA6000 features superior performance, routing and mixing functions to accommodate even the most discerning set of ears. A stereo Aux Input on each channel allows each performer to balance the Direct In signal with a second input for a more customized mix. When a conditioned mix has to reach multiple listeners, the HA6000 delivers it in style. The HA6000 offers 6 high-power amplifiers that can drive loads down to 8 Ohms. Each amplifier features its own 2-band EQ, 8-digit LED output meter, Left and Right Mono switches, and a 14 " stereo Aux input to mix in any instrument or sound source and a dedicated 14 " Phones Out jack. HA6000's Main Section features a 8-segment LED input meter, Direct In 14 " jack and Master Level dial. On the back panel you'll find an additional 14 " output per channel. That means up to 12 pairs of headphones can listen to 6 separate mixes at once. The back panel also features stereo 14 " and XLR Inputs and Outputs, so you can connect multiple HA6000 units for even greater listening capacity. Meanwhile, the HA6000's ultra low-noise operational amplifiers deliver the ultimate in rock-solid, audiophile-grade performance.

Notes: An articulate headphone mix can make all the difference in the outcome of a recording session. The 8-channel POWERPLAY PRO-8 HA8000 features superior performance, routing and mixing functions to accommodate even the most discerning set of ears. Two independent stereo Main Inputs, along with a dedicated Direct Input on each channel allows individual performers to obtain a more customized monitoring mix. When optimized mixes have to reach multiple listeners, each with their own specific requirements, the HA8000 delivers high-quality headphone mixing - in a class all its own!

All Together Now:
The HA8000 offers 8 high-power amplifiers that can drive loads down to 8 Ohms. Each amplifier section features its own 8-digit LED Output Level meter, Main In 1/Main In 2 select switch, a stereo or dual mono select switch, and a 14" Direct Input for integrating an additional sound source. The front panel gives you one 1/4" Phones Out jack per channel. The Main Section features a dedicated 5-segment LED Input meter, plus Main In 1 and Main In 2 Level dials.

Connections:
On the back panel you'll find an additional 1/4" Phones Output per channel, allowing up to 16 pairs of headphones to listen to 8 separate mixes at once. The back panel also provides access to the HA8000's per-channel Direct Inputs and the Main 1 & 2 Inputs.

Great Sound, Great Value:
When a recording session calls for everyone's head and ears to be in the game, the POWERPLAY PRO-8 HA8000 is essential - and ultra-affordable. With 8 discrete channels and the ability to connect up to 16 sets of cans, this is one tool you will use every day.

Notes: Designed with Brian Hamilton from smallsound/bigsound for OBNE demo boards, Old Blood Noise deemed it a reasonable idea to offer every bedroom player a way to not annoy those around them. Simply plug in the output of your pedalboard to the headphone amp, plug in headphones and blast your volume. Play whatever you like, you're the only one who can hear. Or a buddy can plug into the additional Headphone output. Headphone output is mono out.

Two 1/4 Headphone Output jacks allow two users to simultaneously listen.

9VDC

Notes: Are you and your session players and bandmates tired of straining to hear underpowered headphones? That's why Jim Odom and his jambalaya-fueled team of engineers designed 150 mW headphone amps for the HP4 headphone-distribution system.

These headphone amps are not just loud enough for session and stage use, they're loud enough to explode the oysters in a Po' Boy sandwich. Yet the sound is clear and clean, with a wide dynamic range. At last, everybody will be able to heariassuming they are capable of hearing. Be careful with that level control.

Simplicity is the HP4's hallmark. You get left and right line inputs, left and right line outputs with level control, and the 4 x headphone outs. You can globally mute the headphone outs, adjust the overall headphone level, sum the stereo signals to mono, and mute the rear-panel Monitor outputs.

The HP4 can sit on a tabletop or can be screw-mounted to a standard rack tray (not included), where it requires just 1/3 rackspace. And if your needs grow, you can use the line outputs to feed the inputs of a second HP4 or an HP60. Chain as many headphone systems as you need.

So listen up. Quit struggling with mediocre headphone amps. Get the HP4 and hear everything loud and clear. You owe it to your music.
