GLENSOUND HEADPHONE AMPLIFIERS

A range of headphone amplifiers with and without Dante audio input, from Glensound. Designed for use in studio or broadcast, this range includes headphone amplifiers can be portable, desk or permanently wall mounted.

VIRGIL Series - Dante

Ordering note: The standard versions of Virgil headphone amplifiers listed below feature a front panel pot range of -20 to +10dB. The same units can be ordered as a special order with a pot range of -70 to +10dB. Please contact our Sales team for more information.


Virgil - Install

Powered over PoE, Glensound Virgil studio headphone amplifier with Dante audio inputs is designed for permanent install into studio, production room, or stadium commentary box. Two audio channels can be received from a Dante network with one sent to the left and the other to the right channel of the headphone amplifier. A volume pot on the front facing panel allows the user to determine the audio level send to the headphones. As the volume pot allows adjustment from -20 to +10dB it’s worth noting the audio signals will never be turned completely off. Instead they can always be heard, at worst at low volume, so that important announcements aren’t missed. If the user wishes to have the volume turned off, a hardware soldering job can be done on the internal PCB. Otherwise a -70 to +10dB version can be purchased as a special order item.

The rear facing panel houses RJ45 network connection for Dante audio and PoE, and a dual purpose 5V USB socket that can be used to power the Virgil from a compatible USB power adapter, or upload new firmware if required.

The front facing panel of the headphone amplifier features the rotary volume controller, 6.35mm and 3.5mm headphone jack outputs, and ‘bright’ blue LED signifying power.

GS-HA009 has been designed to be used as a mono belt pack headphone amplifier and is suitable for driving mono or stereo headphones and earpieces from 8-2000ohms. The amplifier has a small inbuilt loudspeaker to be employed for simple monitoring. THe loudspeaker is automatically disconnected when a headphone jack connection is made. A on/off switchable limiter is built in for the protection of a user's ears from sudden loud input signals. The audio input is by way of balanced 3-pin XLR with a male 3-pin XLR connection also provided as a loop through for daisy chaining several devices together. The top facing panel hosts the 6.35mm headphone jack connection, a rotary output level controller and a 20dB gain switch to boost the input level if required. Powering is via a single 9V PP3 battery cell, and as the GS-HA009 runs at a very low current it is said by Glensound to 'provide a very long battery life'.


GS-HA010 - Portable, single amplifier

GS-HA010 is a portable, beltpack style device with single channel inbuilt headphone amplifier that is described by Glensound as 'very rugged to withstand the rigours of portable use'. Optimal impedance of headphones to be used is 32-1000ohms.

Audio input is via balanced 3-pin XLR with a loop through also on 3-pin XLR connection. Both in and out connections are positioned on the bottom of the headphone amplifier. On the top facing panel of the GS-HA010 are two headphone sockets, with one being via 6.35mm jack connection and the other on 3.5mm jack connection. These outputs are wired tip and sleeve to allow connection of standard stereo headphones with audio on both ears, or a single ear piece. A rotary volume control is positioned next to the output connections for adjustment of level for 32-1000ohm impedance headphones. Power is via a 9v PP3 battery, which allows approximately 18 hours of use, or via external DC power. There is an on/off switch and an LED to signify low battery power.

Along with a belt clip on the rear facing side, there are loop anchor points on each of the front corners for compatible shoulder straps or for tying down.

SIGNATURE HA+ Series

Glensound HA+ series of headphone amplifiers have been designed and manufactured to broadcast specification, and to operate in a mono or a stereo mode. They have a 1U, 19-inch rackmount chassis however the rack frame can also be removed allowing desktop or under-desk mounting.

Ordering note: Glensound suggest that the below headphone amplifiers 'may be delivered with a black finish'.


HA1+ - 1 amplifier

Glensound HA1+ has two 3-pin XLR inputs that are used as the primary programme audio input. This can be stereo, or, if mono, can be switched to appear on both sides of the headphone outputs. There are left and right programme input gain controls on the front panel, and they are on recessed screw terminals to prevent accidental tamper. There is also a secondary, mono cue input with a connection via one of 3-pin XLR sockets on the rear panel. HA1+ uses Glensound’s proprietary CAN headphone system to allow multi-impedance headphones to be used, between 32-1000 Ohm, with the same perceptual level in the headphones when the volume control is kept in a fixed position. Stereo or mono connections can also be made to the headphone sockets, including mono earpieces. The headphone output is available via a front panel 6.35mm headphone socket, and in parallel on a rear panel 3-pin XLR connection.

A remote connection available via an RJ45 or a 9-pin D-type connection to allow the user to remotely adjust level control, the disabling of front panel control, and further left/right signal outputs. Rear panel inputs and outputs are electronically balanced on 3-pin XLR connections, however unbalanced connections are also accommodated. Power is provided by an internal switch mode power supply, with a wide input range. There is also an input for external 12V DC power. The 12V DC input can be connected to the optional Signature PS1 external DC Master Power Station, for situations where a redundant power supply is desirable. A bright front panel LED indicates that the unit is operational.
