The new PH-100 is a remarkably quiet, 1U rackmount headphone distribution amplifier. Each output has its own amplifier as well as its own level control - so different individual listening requirements can be met with ease. Multiple PH-100s can also be cascaded to handle a large number of listeners making it ideal for orchestral, multimedia, education and trade show applications. The PH-100 is especially handy in the studio environment because an output from the mixer can send a talkback signal to the Aux input (complete with level control) of the PH-100 and be distributed to all headphone outputs. This great cue system makes for more effective communication between engineer/producer and musicians. Flexibility is further enhanced with all ten outputs being available both on the front and r ear panels.
* Ideal for studio, orchestral, education, multimedia, conference and exhibition applications * 10 headphone outs - each with its own amplifier * Each input routes to its direct output, plus Aux 1 source (cue feed) * Multiple inputs: XLR, phone, RCA pin jacks * +4dBu or -10dBV switchable for balanced inputs * Individual level controls with peak reading LED * Stereo or mono input select * Cascade inputs & outputs for ?daisy chaining? units * Aux In with level control for cue feed from main mixer

Sides Cast Aluminum | The LD Systems HPA 1 is a versatile headphone amplifier with high power output for stage, studio and home recording and is the perfect solution for wired in-ear-monitoring.. The compact device in a rugged, ergonomically shaped plastic housing with soft-touch surface and practical belt clip is very extensively equipped.
In addition to locking XLR connectors for the stereo signal L/R input, the HPA 1 has a balanced 3.5 mm stereo jack as AUX input, which can be used in parallel for clicks or playback. It is protected for safe operation against excessive input levels; a hollow pin socket with negative internal contact enables the connection of a network adapter for fixed operation.
A 3.5 mm stereo jack is provided as earphone and headphone output. Volume level and balance can be set with easy-grip knobs, a push-button switches between the summed mono and stereo signals. A full-fledged limiter is integrated for distortion-free playback and as protection against feedback.
The LD Systems HPA 1 has bi-colour LEDs to facilitate the features overview, which displays the response of the limiter during peaks and the battery status. At 165 grams, the headphone amplifier is distinctly light-weight and can be operated for up to 12 hours thanks to a high quality 9 V block battery.
