USP-1 Front Panel Layout (for larger image, see page 24) * Input Indicator LEDs LEDs above each selectable button illuminate when the labeled function is engaged. All of the labeled indicators are available as remote commands. When receiving commands, the COM/RECV LED illuminates as well. 1. Headphone Jack Standard 1/4” gold -plated Headphone jack is provided on the front panel. 2. CD Player Source Selection Button Selects a properly connected CD player as input source. 3.
Any selected input will pass through to the Tape Monitor outputs except when the tape monitor is selected. When the Tape Monitor is not selected, the selected input is sent to the main outputs as well as the tape monitor outputs channels. When the Tape Monitor is selected, the Tape Monitor input is sent to the main output channels. 10.
USP-1 Rear Panel Layout (for larger image, see page 25) 1. TRIGGER OUTPUT Allows a mono to mono 3.5mm cable to remotely trigger another device on and off, along with the USP1. Current is limited to 500mA, which is sufficient to trigger two devices. For triggering more devices, you may want to use a separate triggering device, like the Emotiva ET-3. 2. PHONO INPUT Section (clockwise from top left) • Phono Ground • Left and Right channel RCA inputs • MC/MM Switch.
AUDIO OUTPUT SECTION 6. Low Pass Filter Frequency Control Rotary knob for selecting the low pass frequency, which can be set from 50Hz to 250Hz, with a slope fixed at 12dB/Octave. 7. Balanced Subwoofer Output Balanced (XLR) subwoofer connection, with low pass frequency controlled by the rotary knob directly above it (6.). 8. RCA Subwoofer Output Standard RCA subwoofer connection, with low pass frequency controlled by the rotary knob directly above it (6.). 9.
USP-1 Remote The USP-1 has a dedicated remote control that offers discrete buttons for most of the critical USP-1 controls. Power Buttons Discrete buttons to turn the USP-1 on and off, as indicated. Volume Controls Applies continuous increase (+) or decrease (-) in volume levels while buttons are held down. The USP-1 volume knob moves in correspondence with these controls. Source Selection Buttons These buttons select the various source inputs of the USP-1.
Bass Management – Low Pass/High Pass Filters The USP-1 offers a full range speaker connection, as well as offering a bass management system that allows you to optimize your sound when using a powered subwoofer. Bass Management Close-up: 1. Low Pass filter frequency control 2. Balanced (XLR) subwoofer output 3. RCA subwoofer output 4. High Pass filter frequency control 5. High Pass left and right speaker outputs 6.
Low Pass/High Pass Outputs Recommended for users with speakers that do not have the capability to produce low bass tones (below 80Hz). Bookshelf speakers, smaller ‘satellite’, and home theater style speakers may be incapable of producing lower bass tones, either by design or simple size limitations.
Connecting Audio Source Units The USP-1 can connect to up to seven different audio devices, using standard RCA analog connectors. PHONO Connects to a turntable using standard RCA type connectors. Connect the Left output on the turntable to the Left input of the PHONO INPUT section on the USP-1, and the Right output to the Right input of the PHONO INPUT section of the USP-1. Also note the connection of the chassis ground tab between the turntable and preamplifier.
TAPE This ‘loop’ connects an external recording device to the USP-1 preamplifier via RCA outputs and inputs. While this traditionally has been a cassette player or DAT player, this connection could also be a hard drive based recording device as long as the input and output connections are analog RCA audio connections. To enable the tape monitor loop you must connect to the inputs AND outputs on the USP-1 labeled "TAPE" on the rear panel.
Troubleshooting Guide The Emotiva USP-1 is expertly designed and built to provide years of trouble-free performance. Most problems that occur can usually be solved by checking your connections or making sure that the audio and video components connected to the USP-1 are on and fully operational. The following information will help you deal with common problems you may experience during initial use of your unit. If problems persist, contact Emotiva’s service department for assistance.
• Check that the amplifier(s) power output is a good match for your speakers. If your speakers are inefficient, consider using larger power amplifiers. • Make sure all wiring is correct and there are no shorts. If wires have been run under carpet, under base boards (or along tack strips) there is a possibility they can easily be shorted by sharp edges or something that punctures the insulation.
• If the hum is heard from within the USP-1 and not through the speakers, this may also be caused by interference on the AC or DC lines. The power transformers may turn this interference into an audible noise. Internal hum can be made worse by a shelf or cabinet resonating, so try moving the USP-1 to another shelf. • Try moving your components further away from the TV, especially if you ever notice the screen has changed color in the area closest to the component.
