Penrose
Headphone Delay
Compact headphone amplifier with auto-calibrated delay to time-align DJ headphones.
The Penrose Headphone Delay is an innovative headphone amplifier that solves the time alignment issues often found in DJ booths of nightclubs and touring installations. With its automated calibration method or a user-supplied delay value, it aligns the headphone output of DJ mixers to the monitors in the DJ booth. This greatly improves the DJs' performance and comfort when cueing and mixing tracks by giving them clearer and more accurate timing information from the monitors.

Connectivity
The device is connected directly to the mixer headphone output. In this way, the DJ can stay focused on the mixer and adjust the headphone level as they are used to. A short angled stereo (TRS) 1/4” jack is included with device.
The device offers two standard headphone outputs: stereo 1/4” and 3.5 mm jack. These are signaled on the device with lettering for ease of access.
The device is securely attached to the mixer with magnets and a tab sliding underneath the mixer, even in case of forceful disconnection of the headphones.
Configuration
The device can be configured from a web browser on a smartphone or laptop through an embedded Wi-Fi access point accessible with a switch. The configuration is saved in between uses.
A calibration microphone is embedded in the device to perform automated calibrations. In this mode, test signals are sent from the device through the mixer to the monitors. Then, the device automatically computes the required delay to time-align the headphones. A 3.5 mm stereo jack to RCA cable is included with the device for these measurements. The user can also input a delay amount from prior measurements.
