The RockBoard HA 1 in-ear monitoring headphone amplifier is the ideal companion for singers, keyboardists, drummers, guitarists, bassists and other musicians. It establishes the connection between the monitor signal from the mixing console, instrument or amp and your own headphones. Operation is child's play: simply activate the device with the volume control and set the desired volume for the headphone signal. With the stereo/mono source switch, which is easily accessible on the device, the RockBoard HA 1 can be adjusted to the available input signal. The extremely compact and lightweight aluminium housing is fitted with a clip for attaching to a belt or waistband. The HA 1 has a status LED which changes colour depending on the available battery voltage. Two AAA batteries (not included) provide up to 12 hours of power supply and the batteries can be changed in no time at all thanks to the practical battery compartment with clip fastener, which is accessible from the outside. The HA 1 is equipped with a combination socket for use with stereo jack (6.35 mm) and XLR cables for the input signal and a 3.5 mm stereo jack headphone output. On stage, in the rehearsal room or at home, the RockBoard HA 1 in-ear monitoring headphone amplifier always offers full control over the monitoring signal. In small clubs, in-ear monitoring improves the acoustics in the room, and when the band turns up the volume again, the signal is quickly adjusted and you can enjoy the same sound in every part of the room.

The Body Pack XL has the same functionality as the Fischer Amps Hard Wired In Ear Belt Pack, but an additional microphone input has been integrated so that a microphone signal can be added to the incoming stereo or mono mix. The built-in low-noise microphone preamp has the standard features such as switchable 48V phantom power, a PAD switch to attenuate the input signal by 16 dB and a gain control from 0 dB to + 60 dB.There is also a parallel-out socket for the microphone input to allow the microphone signal to be looped through. Power is supplied by a 9V battery.The device is ideal as a compact in-ear solution, e.g. in an orchestra, if the musician wants to add his own microphone signal to the incoming in-ear signal. The device is also ideal as a technician's tool for monitoring microphone signals.

BOOSTi² is a further development of the proven BOOSTi headphone amplifier. It is suitable both as a sound and performance enhancer for existing systems and as a stand-alone headphone amplifier. Both state-of-the-art circuit technology and high-quality components - such as a high-quality ALPS stereo potentiometer with very good synchronisation properties - are used in this new product. The amplifier in proven AB mode delivers a gain of 20dB. The circuit concept provides two balanced inputs (either via XLR or 6.3 mm jack). Two independent, parallel-connected unbalanced 6.3 mm jack sockets are available at the output for two headphones to be operated.

The LD Systems HPA 1 is a versatile headphone amplifier with high output power for stage, studio and home recording and the perfect connection solution for wired in-ear monitoring. The compact device in a robust, ergonomically shaped plastic housing with a soft-touch surface and practical belt clip is extremely well equipped.In addition to locking XLR connectors for balanced input of the stereo signal L/R, the HPA 1 has a 3.5 mm stereo socket as an aux input, which can be used in parallel for click or playback tracks. It is protected against excessive input levels for safe operation, and a hollow pin socket with negative internal contact enables the connection of a mains adapter in fixed mode.A 3.5 mm stereo socket serves as a headphone and earphone output. Level and balance can be adjusted using handy rotary controls, while a button switches from stereo signal to mono sum. A fully-fledged limiter is integrated for distortion-free playback and protection against feedback.The LD Systems HPA 1 has two-colour LEDs to provide an overview of its functions, which indicate the response of the limiter at peak levels and the battery level, among other things. At 165 grams, the headphone amplifier is extremely lightweight and can be operated for up to 12 hours with a high-quality 9V block.

Fischer Amps Mini Body Packs with XLR input and volume control are used to control the volume directly at the musician. This system allows short cable runs on stage and cabling with standard microphone cables. The Class A MOSFET power amplifier has power switching, so that it is possible to work with headphones with high impedances as well as with low-impedance in-ear receiver systems. The XLR inputs have parallel XLR outputs, which makes it possible to loop through to the next device. This makes it very easy to provide a stereo mix for a large number of listeners.The ideal system for orchestras, studios, conferences and cool computers.

The HP60 headphone amplifier, designed as a 19" rack unit, can supply up to 6 musicians with individual headphone mixes thanks to its clever circuit design. The output power is 2x 150 mW per channel (at 60 Ω ), the HP60 delivers an extremely loud headphone signal with very low noise and distortion values if required .On the input side, the HP60 can be fed via 4 balanced jack sockets from two different stereo sums - e.g. bass/drums and guitar/keyboards or between headphone playback and click track. The balance between these two stereo sources (A/B) can now be set separately for each of the 6 channels using the "Mix" control. In addition, each channel has a further adjustable stereo input ("External") to which, for example, the signal of the respective musician himself can be fed ("I can't hear myself loud enough..."). If required, this external source can be switched to mono using a button (ideal for vocals and soloists). If the balance is right, the overall volume of the relevant channel can be adjusted using the "Level" potentiometer. Finally, the "Mute" buttons can be used to mute the two stereo sources per channel, which is practical if you want to control the "external" signal in isolation. Each of the 6 channels also has a stereo output via which the respective mix - before the level control - can be looped through to other devices, e.g. other headphone amplifiers.There is an XLR socket at the rear to which a dynamic talkback microphone can be connected, which can be activated at the front using a button and the volume can be adjusted using a potentiometer. The talkback function can also be activated by foot: The HP60 has an additional jack socket for connecting a standard foot switch.

The HM-800 19-inch rackmount 8-channel headphone amplifier offers up to 10 available mixes with a total of 16 headphone outputs. Perfect for professional applications such as studios, houses of worship, practice rooms and more. Equipped with 2 discrete main inputs with level control as well as stereo outputs and aux inputs per channel.

The mono or stereo signal fed in is output to four outputs, the volume of which can be adjusted separately. A mono switch on the front panel routes both input signals to both sides. The highlight is an additional volume control for two connected control boxes, which can also be muted using the monitor mute switch.

Two Burr-Brown OPA 2134 SoundPlus™ operational amplifiers take care of the pre-amplification. These have been specially developed for audiophile circuits and are characterised by extremely low noise and minimal distortion of just 0.00008%.Thanks to a genuine FET stage, the OPA2134 achieves a slew rate of 20V/µs, making it a high-speed operational amplifier. This has an immediate positive effect on the liveliness and joy of playing.Furthermore, low-capacitance film capacitors are installed in the signal path as bypass capacitors for the coupling capacitors, which ensures more precise transmission of the high-frequency signal components.The excellent Panasonic 'Electric Double Layer' gold electrolytic capacitors are used as coupling capacitors. They offer the highest storage capacity of all capacitor technologies.The output stage of the headphone amplifier is designed as a push-pull amplifier in Class AB operation. The bipolar transistors share the amplification of the positive and negative half-wave, which produces a higher amplification and a higher output voltage than in Class A operation, in which only one transistor amplifies both half-waves.The output stage transistors are thermally coupled and therefore run particularly coherently, which contributes to a consistent and stable sound image.The power supply has a buffer circuit with low source resistance and thus ensures generous current reserves even when operating low-impedance headphones.The Phonitor Matrix has three setting parameters in the largest configuration: Crossfeed, Speaker Angle and Centre Level.In Phonitor One d, the centre level is preset to -1 dB and the speaker angle to 30°. These are the most commonly used values.The crossfeed function determines the crosstalk between the channels, the so-called interaural level difference. The intensity of the crossfeed is infinitely variable.At the beginning of the control path, the function is not in the audio path. It is only switched on by adding it via a relay (hysteresis circuit). The audio signal therefore does not pass through the crossfeed stage if this is not desired.

This is where you lay the foundation for the performance of the entire device.Although we "only" supply a 12 V plug-in power supply, the secondary power supply generates a voltage level of +/-17 volts for the analogue audio sections, with which professional levels of up to +22.5 dB can be achieved!A sophisticated low-drop operating voltage control provides more "juice" and regulates cleanly even when maximum voltages are reached.The Phonitor One delivers full power when operated with the supplied 1.5 A power supply unit. Only use the external power supply unit supplied. The ON switch switches the Phonitor One on.

Compact monitor system. Ideal for musicians who want to mix an instrument with their microphone and the main mix.

The Lake People Phone-Amp G103D4 is a headphone amplifier for DANTE networks.The G103D4 model has a Dante 4/4 input and two independent stereo amplifiers. 24-bit/192 kHz D/A converters with a signal-to-noise ratio of >105 dB and a distortion factor of only 0.002 % drive the powerful headphone amplifiers. These are best suited for driving headphones with low to high impedance and low or high sensitivity. To adapt the amplifier to demanding headphones, to further reduce the noise level or to maximise the control travel of the volume control, the gain can be adjusted internally via DIP switches to optimise the amplifier.The digital DANTE audio signals are fed in via a standard RJ45 connection. The Lake People G103D4 accepts 4 audio channels. The unpacked audio signals are forwarded to two high-quality D/A converters. The restored analogue signals are buffered, attenuated in the analogue range and then forwarded to powerful headphone amplifiers.If required, it is possible to set an additional gain of +6 dB or +12 dB via DIP switches in the amplifier. Each amplifier section has a 1/4" and a 3.5 mm jack socket that can be used simultaneously.The amplifier is powered either via PoE (Power-over-Ethernet) or via a USB plug-in power supply adapter (not included) with USB-B or USB-C connection.
