-The EQ-251A equalizer has two sliding levers: an equalizer and an attenuator. The levers for the equalizer and attenuator slide vertically, making it easy to read the knob positions and adjusting the levels in 2db steps.

-Ideal for correcting frequency response, from a maximum of +12db equalization to a minimum of -16db attenuation.

-This assembly is passive, with only L/C/R and bridged T networks, and can be inserted directly into the transmission line with only input and output connections. No power supply or amplifier is installed.

-There are two rotary cam switches on the face panel,

the right switch sets the four high-frequency equalizer peak values ​​of 3kHz, 5kHz, 10kHz, and 15kHz, and the left switch sets the low-frequency equalizer peaks of 40Hz or 100Hz.

<Features>

2. The impedance of the INPUT and OUTPUT is set to 600Ω, respectively, to maintain normal frequency response

3. Mounting dimensions

Size: W38mm x H88.6mm x D145mm

Weight: 610g

By mounting the knob vertically at eye level, you can control it by ear without relying on the scale.
