Behind-the-Ear (BTE) Transistor Hearing Aids

Widex Quattro Model Q-9 Behind-the-Ear (BTE) Transistor Hearing Aid

The Widex Quattro was a digitally-programmable analog hearing aid. It allowed the person fitting the hearing aid to program it for maximum power output, gain, low and high cut filters and an inverse presbycusis filter.

Like the Q-8, the Q-9 model was designed for mild to moderate hearing losses. It featured a toggle lever to control volume (push up to increase volume, push down to decrease it) rather than the usual wheel type used on most BTEs.

The Widex Quattro Q-9 hearing aid had the same parameters as the Q-8, but was equipped with a dual-port directional microphone.

The hole above the toggle volume control is the rear port for the directional microphone. (See top picture.)

The Q-9 uses a single microphone with  two openings (ports)—one to the front and one at the back—to make it into a directional microphone.

The Widex Quattro Q-9 in it's original box. It came with one of two styles of remote control units—the larger model (pictured at right) came in maroon or grey color.

Here is the Widex Quattro manual. (Be patient as it is about 17 Mb so takes a few seconds to download and open.) Pages numbered 9 and 10 explain the use of the (large) remote control.

The smaller model, which came in black, is shown here. This remote measures 3" x 1 13/16" x ¼". It was powered by two CR-2032 lithium batteries.

The remotes, which offered four memory choices, also served as the programming unit for their hearing aids. The hearing aid fitter inserted a programming key (shown on the right) into the slot (center), set the parameters and then locked these parameters in by removing this key.

The two remotes beside each other for comparison in size and placement of controls. The buttons have the same function, but the layout between the two models is slightly different. The "M" and "T" buttons lie between the left and right volume control buttons on the smaller unit instead of below them.
