IPS-1 Front Panel Features 3 2 1 1 Power Button This turns the main power to the IPS-1 on or off. It is a main power button, but it is not required to turn this on and off each time the IPS-1 is used. When enabled, the AUTO ON/OFF MODE will automatically switch the amplifier on when an audio signal comes from a source or control unit (such as a preamplifier). The TRIGGER MODE will turn the amplifier on when an external source (such as a preamplifier) provides a 5-24 VDC input on the trigger terminals.
IPS-1 Rear Panel Layout 4 5 1 2 6 7 3 8 1 RCA Inputs The IPS-1 has one RCA input available for each amplifier channel module. Connect this to the corresponding RCA jack on your preamplifier to provide signal to the amplifier channel. See page 15 for a connection diagram. 2 Channel ID Area The IPS-1 amplifier comes with self adhesive labels to use as channel identification.
4 Turn On Selector Switch Turn On Selector Switch This switch allows you to select how the amplifier will turn on and off. In the ON (Up) position, the switch on the front of the amplifier is the method you will use to power up and power down the amplifier. Please note that in this configuration, you must manually power up and power down the amplifier each time you use it or it will have unnecessary standby current draw.
Installation and Connections Observe the following precautions when choosing a location for your Emotiva IPS-1: 1) Protect it from prolonged exposure to direct sunlight and other direct sources of heat, such as heating vents and radiators. 2) Do not expose the unit to rain or moisture. If fluid or a foreign object should enter the unit, immediately turn off the power and contact your Emotiva Dealer. 3) Avoid excessive exposure to extreme cold or dust. 4) Do not place heavy objects on top of the unit.
Output Connection Considerations The output connectors provided on each channel of the IPS-1 are standard “binding post” speaker connectors with industry standard spacing. These are sometimes called 5-way binding posts because of the many ways in which the speaker wire can connect into the posts. The posts can accept bare wire, spade terminals, and dual or single banana connectors.
Connection Diagrams Input Connections If your preamplifier has RCA outputs, it can easily be connected to the amplifier inputs as shown. The amplifier will boost the preamplifier’s output, up to a level suitable for driving speakers. Make sure that the positive speaker wires do not touch the negative speaker wires, or any chassis metal. This will cause a short circuit and may activate the protection circuitry.
12V Trigger Connections The 12 VDC trigger connection shown can be used to turn the amplifier on when the preamplifier turns on. This trigger will actually trigger with any switched DC Voltage from 5-24 VDC, however the majority of home theater components use a standard 12 VDC trigger connection for this function. This is the preferred connection as it has the greatest degree of reliability. Never switch anything that plugs directly into the wall with this trigger connection.
Series and Parallel Speaker Connections Whenever connecting more than one speaker per channel to an amplifier (regardless of the brand), you must consider the way in which the amplifier will be impacted by adding the additional speaker(s). Additionally, speakers with dual voice coils also apply to this consideration. Two voice coils in a single speaker also cause different reactions from an amplifier depending on the way in which they connect to the amplifier.
Parallel A parallel circuit is established when voice coils are connected in a way that there are multiple paths for audio signals to flow “in” and multiple paths for audio signals to flow “out”. When speakers are connected in parallel, the total resistance at the amplifier is proportionally divided based on the value of each individual voice coil resistance. The term “divided” simply means all of the values together in parallel are a SMALLER value than each all by itself.
Flexible IPS-1 Applications 5.1 and Zone 2 Amplification This example shows the IPS-1 with the companion MMC-1 preamplifier/processor used in a 5.1 and Zone 2 arrangement. If you are not intending to use side axis speakers in a 7.1 system, the IPS-1 amplifier is ideally suited for this configuration. As an example, a CD Player, iPod with dock, and DVD player are shown as source inputs to the preamp. Obviously, the actual components you might connect depend on your own system.
Speaker Placement Tips Tips Before You Begin Read this section thoroughly. There are a number of ways in which it may seem aesthetically pleasing to place speakers in a room that will ultimately result in a sound quality compromise. The placement of speakers is equally as important as the room itself. While there may be very little you can do about the room where your home theater is installed, you can choose placement of speakers within that room to maximize the sound quality of the system.
The Front Speakers You should closely follow the placement recommendations of your speaker manufacturer, with the addition of the following points: • The left and right front speakers should be positioned so that your TV is exactly centered between them. This will help focus your attention towards the screen. • For the best overall imaging, the left speaker should be set exactly the same distance and angle away from your listening position as the right speaker.
Side-Axis Speakers Some preamplifier processors feature side-axis channels which are matrixed and derived from the left and right front channels, so they are available in stereo as well as surround modes. If available as a feature, the processor should have a set-up menu to turn the SIDE-AXIS channels ON or OFF. In the diagram to the left, typical placement of side-axis speakers is depicted by the speakers that appear to be “suspended” where walls are in the room.
Surround Back Speakers Many preamplifier processors feature additional outputs for surround back speakers. These create a wonderful sense of realism in surround effects during playback of Dolby Digital EX, Dolby Pro Logic IIx, and DTS ES. Ideally, all the surround speakers should be of the same make and model as the surround speakers, and fitted at similar heights to produce a smooth continuous sound field.
2 Play a test tone or low bass music 3 1 Place the subwoofer in the listening position Walk around the room and see where the bass has the best performance. That’s where your subwoofer belongs! Notice where in the room the bass output from the subwoofer sounds the loudest. Shut things down and install the subwoofer there. This is the best position for the subwoofer. The bass will sound the best when you are sitting in your normal listening position.
Troubleshooting Guide The Emotiva IPS-1 is expertly designed and built to provide years of trouble-free performance. Most problems that occur can usually be solved by checking your setup or making sure that the audio and video components connected to the amplifier are on and fully operational. The following information will help you deal with common setup problems you may experience during normal use of your unit. If problems persist, contact your Emotiva Dealer for help.
Poor Bass Performance From Full Range Speakers connected to the IPS-1 • Make sure that your preamp does not have the bass (tone control) level turned down. • Many surround preamplifiers have controls which can direct all the bass to subwoofers or let your main speakers play the full range. Make sure that the preamplifier has been correctly set. If you are not using a subwoofer, set the speaker options to “Large” where possible.
• Check that the interconnect cables to the amplifier do not have any broken connections. The best way to do this is to substitute a known good connection for the suspect connection. If you reverse the cables and the problem goes away, the cable may be damaged or broken. This is possible even if you can’t physically see the break as the strain for pulling on audio cables can sometimes break the wire internally.
