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.\u003c\/p\u003e\n\u003cp\u003eThere are also secondary, mono cue inputs. Connections are via one of 3 x 6.35mm jack sockets on the rear panel. This allows a single cue input to be connected to both headphone outputs, or each headphone amplifier can receive an individual cue input.\u003c\/p\u003e\n\u003cp\u003eOn the front panel there is a source control for each headphone output that allows a mix between the programme and cue input. Full left is programme only, full right is cue only, and anywhere in between is a variable mix.\u003cbr\u003e\u003cbr\u003eEach of the two headphone amplifiers has its own volume level control. There is also a master volume control that affects the overall level of both amplifiers. This can be defeated via a rear panel dip switch.\u003c\/p\u003e\n\u003cp\u003eThe headphone outputs are available via 2 x front panel 6.35mm headphone sockets, and in parallel on 2 x rear panel XLR connections.\u003cbr\u003e\u003cbr\u003eThe Expedition uses Glensound’s proprietary CAN headphone system. This allows multi impedance headphones to be used, from 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.\u003c\/p\u003e\n\u003cp\u003eRear panel inputs and outputs are electronically balanced on XLRs and can accommodate unbalanced connections if required.\u003c\/p\u003e\n\u003cp\u003ePower 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.\u003c\/p\u003e\n\u003cp\u003eA bright front panel LED indicates that the unit is operational.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eMay be delivered with a black finish\u003c\/p\u003e \u003c\/div\u003e\u003ch4\u003eTechnical Information\u003c\/h4\u003e\u003cdiv class=\"tab-content\" id=\"tab4content\"\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eAUDIO INPUTS\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eMaximum Input Level:\u003c\/strong\u003e  +24dBu\u003cbr\u003e\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e  30k\u003cbr\u003e\u003cstrong\u003eProgramme Input Type:\u003c\/strong\u003e  Sophisticated electronically balanced \u003cbr\u003e(can be wired unbalanced)\u003cbr\u003e\u003cstrong\u003eProgramme Input Circuit:\u003c\/strong\u003e  Stereo or mono (via rear panel switch)\u003cbr\u003e\u003cstrong\u003eProgramme Input Connectors:\u003c\/strong\u003e  2 x Neutrik 3 pin XLR sockets\u003cbr\u003e\u003cstrong\u003eCue Input Type:\u003c\/strong\u003e  Sophisticated electronically balanced \u003cbr\u003e(can be wired unbalanced)\u003cbr\u003e\u003cstrong\u003eCue Input Circuit:\u003c\/strong\u003e  Mono\u003cbr\u003e\u003cstrong\u003eCue Input Connector:\u003c\/strong\u003e  Neutrik A gauge 6.35mm (1\/4”) jack socket\u003cbr\u003e\u003cstrong\u003eCoarse Gain Range:\u003c\/strong\u003e  +\/-10dB on programme input only\u003cbr\u003e\u003cstrong\u003eFront Panel Volume Pots Range:\u003c\/strong\u003e  75dB (-65dB to +10dB)\u003cbr\u003e\u003cstrong\u003eFront Panel Source Control Range:\u003c\/strong\u003e  70dB (-70dB to 0dBu)\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eHEADPHONE OUTPUTS\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eOutput Type:\u003c\/strong\u003e  Sophisticated electronically balanced.  Can accept mono or stereo jacks with automatic level correction for low or high impedance headphones. \u003cbr\u003e\u003cstrong\u003eOutput Connectors:\u003c\/strong\u003e  Front panel Neutrik A-gauge TRS 6.35mm (1\/4\") jack socket in parallel with rear panel Neutrik 3 pin XLR plug\u003cbr\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e  -1.7dB 20Hz, -0.5dB 20kHz\u003cbr\u003e\u003cstrong\u003eMaximum Output Level:\u003c\/strong\u003e  +19dBu\/67.07mW into 600 Ohms and +8dBu\/6.2mW into 32 Ohms\u003cbr\u003e\u003cstrong\u003eDistortion:\u003c\/strong\u003e  \u0026lt;0.01%THD@100Hz \u0026amp;
