EHT-2/4/5/6 and 8

In Wall / Ceiling models

Congratulations on investing in JENSEN’s Architectural Speaker

Systems. You will find this information valuable for the long-term

enjoyment of your speaker system.

Break In Period. Certain parts and materials are used in these EHT-2/4/5/6/8 products so

maximum performance can be obtained in damp and dusty environments such as wall and ceiling
cavities. Therefore, we strongly advise that you resist temptation to play your JENSEN speakers to
their full capabilities until they have been properly broken in. This process should last appx. 20-40
hours of music playback. This can easily be done by putting your compact disc player on Repeat
mode, while playing a CD with reasonable Bass content at average room volume listening levels.

Installation.

Step 1. Decide the placement for your speakers. Advance planning in regards to the placement of

your speakers is critical. It is imperative that the wall or ceiling cavity be free fro m debris,
moisture, insulation, and any materials that are easily combustible. The mounting location must
also be void of wall studs or bracing in the location for the cutout. Adequate depth for the speakers
to fit flush to the wall or ceiling surface is important. If you are unsure of the contents of the wall
in which you wish to mount the speakers, simply drill a small hole and using a metal coat hangar,
insert the end of the hangar into the wall and twist it to feel for any debris or wall studs. Electronic
Stud Finders work well also.

Step 2. Once you have determined the final mounting position, use the supplied template and

mark the cutout on the wall or ceiling, depending on the model purchased. To mark the cutout size,
simply trace an outline of the supplied template, found in the box with a pencil.

Step 3. Using the appropriate wall-cutting tool, accurately cut the hole in the wall material, based

on the appropriate cutout dimension.

Step 4. Install speaker cable(s) from the receiver or amplifier to the inside of the wall or ceiling,

and leave enough slack in the wire so that it can hang out of the hole.

Step 5. Connect the speaker wire from the positive (RED+) terminal on the receiver to the

positive (RED+) terminal on the speaker. Connect the negative (BLACK-) the same way to the
negatives. Note: If you inadvertently reverse one of the connections (i.e. RED to BLACK) you will
notice a severe lack of Bass from your system. This is called wiring your system “Out of Phase”. If
this occurs, check the wiring and reconnect as necessary.

Step 6. Remove metal grilles. (see below) For all models, gently adjust eyeball tweeter to aim

towards main listening area. See below for fine-tuning. For models EHT-2/6/8, set Boost switches
to desired setting (see below). Insert the entire speaker into the hole, and using a Phillips
screwdriver, tighten the screws attached to the dog clamps until firm. NIP THESE UP - DO NOT
OVERTIGHTEN. Note: If you are unable to installthese speakers yourself, please contact an
authorized electrician or installation contractor.

Boost switch. For models EHT-2/6/8, set Bass and Treble switches to either (+) or ( -)

positions. The (-) position maintains a flat, even frequency, while the (+) position will increase the
sound output to the tweeter. Your speakers are factory set to (+) which is recommended.

Centre Speaker Application. All EHT-2/4/5/6/8 models can be used as Centre

Speakers, however for the all important Centre Channel we recommend the EHT-5 which is a true,
dedicated Centre Speaker. Twin 5” drivers and high power handling allow high transient capabilit y
and is magnetically shielded. CRT TV’s require speakers within close proximity to have magnetic
shielding. Plasma, LCD, LED, OLED and Projection screens do not require this.

Rear Speaker Application. The EHT-4 model is unique in that it “projects down-and-

forward” due to its recessed driver mounted at 40 degrees. This tends to cast a wider dispersion
desirable for Rear speaker Home Theatre application.

Painting. Match your room décor by gently removing the grille and use the painting mask

template (supplied) to protect speakers from over spray. Paint grille separately for best results.

Black Bluetack. 6-8 smallpieces are supplied in each carton. If concerned with met al grille

rattling or becoming loose over time, you may use 3-4 pieces per speaker by laying this gum into
bottom of trough and pressing metal grille into same to prevent rattling.

Fine Tuning your Speakers.

To fine tune your speakers, you can adjust the angle of the tweeter slightly in order to compensate
for poor mounting locations. Do this by adjusting tweeter casing. Do not touch the tweeter in any
way as permanent damage may occur.
