WORKING CONDITION: Excellent. This HP-101 was installed in a professional recording studio. All of its working parameters operate perfectly and sound fantastic.

PHYSICAL CONDITION: Very Good. There are a few surface blemishes from use, and some 3M dual lock on the bottom for fastening, but all of the faders, buttons, LED's, and ELCO connection pins are in excellent condition. The power supply and 4-pin cable are also in very good condition. 

INVENTORY #59274

BRAND: Manley Labs

MODEL: HP-101

FUNCTION: Stereo Headphone System

PRODUCT DESCRIPTION: This listing is for a Manley Labs HP-101 Stereo Headphone System w/ Power Supply. The Manley Labs HP-101 Studio Headphone System is a premium, legacy professional studio cue-mixing and audio distribution system. Designed specifically to give musicians high-quality "more me" monitoring control during tracking sessions, it bypasses the weak, integrated circuits found in standard commercial gear to deliver massive, clean power.

SPECS:

• Serial #: MHPE424
• High-Power Output: Features integrated power amplifiers delivering 3 watts RMS per channel into any impedance load from 4 to 100 Ohms. It provides up to 50 volts peak-to-peak into 100 Ohms to easily drive up to four headsets simultaneously without distortion.
• 8 Balanced Line-Level Inputs: Configured via industrial ELCO/EDAC 56-pin connectors with a high 40 kOhm input impedance. 
• Flexible Channel Mixing: Offers four dedicated mono channels equipped with 60 mm faders and pan pots, plus two stereo feeds featuring rotary controls or faders.
• Stereo Image Manipulation (SIM): Allows the stereo channels (Channels 5–6) to switch fluidly between normal Stereo, summed Mono, or specialized spatial image adjustments.
• Onboard EQ & Muting: Includes individual bass and treble shelving controls optimized explicitly for headphone frequency responses. A master mute sequentially steps through full ON, full MUTE, Left MUTE, and Right MUTE. 
• Robust Hardware Protection: Built-in specialized safeguards protect against overvoltage, undervoltage, overload short circuits, and thermal runaway. The circuit design ensures zero transient pops, thumps, or DC leaks during power cycles. 
• Studio Communication: Features built-in Talkback and Interrupt lines routed directly through the primary ELCO interconnects. This permits the control room to seamlessly interrupt or monitor individual station feeds or microphones.
• Inputs: 56-pin EDAC / ELCO connectors.
• Headphone Outs: Four 1/4" TRS parallel-wired stereo headphone jacks on each local station mixer.

ACCESSORIES INCLUDED: This item comes as seen in photos and includes its original Manley power supply and 4-pin connection power cable.
