Congratulations on purchasing the Samson C•que 8 Headphone Amplifier! Although this unit is designed for easy operation, we suggest you take some time out first to go through these pages so you can fully understand how we’ve implemented a number of unique features. The C•que 8 is a compact, high-quality device that allows you to monitor any stereo or monophonic source signal (balanced or unbalanced) over as many as twelve separate headphones. Providing unusually high power levels and superb audio fidelity, the C•que 8 is compatible with virtually all popular headphone models. Front panel controls include a Master Input Level control and Stereo/2 Channel switch. Each headphone output has its own individual Shape Circuit Level Meters, and Level control. Special output jacks on the rear panel allows any number of C•que 8 units to be linked together with no loss of signal. The C•que 8 can be used in a wide variety of applications, including recording studios, teaching labs, broadcast environments, and for live performance. In this manual, you’ll find a more detailed description of the features of the C•que 8, as well as a guided tour through the front and rear panels, step-by-step instructions for using the C•que 8, a reference chart that gives impedance and sensitivity ratings for a number of popular headphone models, and full specifications.

Introduction

C•que 8 Features

The Samson C•que 8 headphone amplifier utilizes the latest technology in gain management design. Here are some of it’s features:

• Four channel headphone mixer amplifier providing individual controls for each channel. Ideal for digitalaudio-workstations, stage and studios.

• Dual headphone outputs; one rear, plus one front panel output per channel allowing a total of eight headphones connected at the same time.

• Maximum output power on each channel regardless of different headphone impedances.

• Left and Right Line inputs for master stereo bus on balanced TRS (Tip Ring Sleeve) 1/4” phone connectors.

• Inject input on TRS (Tip Ring Sleeve) unbalanced stereo phone connector allowing for the insertion of an additional stereo signal that is mixed with the stereo Line input for "more me" mixing.

• 2-Channel/Stereo mode switch configures the C que 8 to operate in traditional stereo mode, or in 2Channel, mono mode.

• Balance controls pan in Stereo mode, or the level balance between the Line and Inject inputs in 2Channel mode.

• EQ Shape circuit on each channel provides a “music contour” equalization curve that boosts the low and high frequencies of the headphone output.

• Each channel has a six-segment, LED Output meter, with a range of –24 to clip, making it easy to monitor the channel output level.

•A six-segment Main Level meter provides a clear and accurate indication of Line input level with an operating range of –24 to clip.

• Stacking Rubber Bumpers are included allowing several C que 8’s, or other Samson C Class units, to be stacked on top of each other creating a neat array of high quality signal processors.

• Tilting Feet are also included so that the C class units can be positioned in a comfortable and ergonomic position on desktops and workstations.
