Overview: The MTX TH650.1D is a mono block Class D amplifier.
It has anodized aluminum heatsinks to dissipate heat generated by the amplifier.
The amp produces 250 watts RMS x 1 at 4 ohms, and 400 watts RMS x 1 at 2 ohms.
1 Ohm Stable: The TH650.1D is stable down to 1 ohms. At 1
ohms, the power output is 650 watts x 1.
Protection Circuits: The TH650.1D provides protection against
overheating and electrical short circuits.
Gain: The amp's rotary gain control is
continuously variable from 250mV to 5V to match the output of the source unit.
Crossovers: The amp features a built-in low-pass crossover,
with a continuously variable cutoff frequency of 40-200Hz. It has a slope of
24dB/oct. In addition, the amp has a subsonic filter, which cuts ultra-low
frequencies to minimize wasted power and protects speakers not capable of
reproducing those frequencies. It has a variable crossover frequency of 20-50Hz,
and a slope of 12dB/oct. Both filters are non-defeatable.
Bass Boost: The TH650.1D's bass boost circuit is variable
from 0 to +12dB, and centered at 40 Hz.
Electronic Bass Control (EBC): The amplifier comes with the
Electronic Bass Control (EBC) module that allows you to adjust the gain of the
amplifier from the front of the vehicle. The EBC comes with a 16' cable which
plugs into the RJ-25 jack on the amplifier.
Smart Engage: When the speaker-level inputs are used, the
amplifier will automatically power on when voltage is detected on the input. No
separate Remote Turn-on lead is required. This is especially convenient when
adding an amplifier to a factory system without RCA outputs, or when adding an
amp and sub in the trunk and you don't want to remove the head unit.
Line Level Input/Output: The line-level signals from the
source unit are input using the stereo RCA inputs. The amp does not offer a
Speaker-level Inputs: If the source unit lacks RCA outputs,
such as a factory head unit, you can splice the two supplied speaker-level input
wires into the head unit's speaker wires, and then plug them into the stereo RCA
Power Terminals: The TH650.1D features set screw terminals for
power, ground and remote turn-on. The power and ground terminals will accommodate
up to 4 AWG wire, while the remote turn-on terminal will accept up to 8 AWG
wire. The set screws can be loosened or tightened with the supplied Allen
wrenches. MTX recommends the use of 4 AWG power and ground wires with the
Speaker Connections: The amplifier is equipped with set
screw terminals for the speaker outputs. The terminals will accommodate up to 8
AWG wires, and can be loosened or tightened with the supplied Allen wrench.
EBC Port: The amp has a RJ-25 modular phone jack for
plugging in the supplied Electronic Bass Control (EBC) module. The EBC comes
with a 16' cable, allowing you to control the gain of the amp from the front of
5 Year Warranty Terms: This product carries a 5-Year
Prorated Warranty with the following terms:
- Years 1-2: Products found to be defective in materials
or workmanship during the first two years will be, at Mitek's option,
repaired or replaced by Mitek at no charge. The warranty period does not
renew, but continues on from the original date of purchase.
- Years 3-5: The purchase price of an item which becomes
defective after the first two years and prior to the end of the warranty
period will be prorated and credited toward the purchase of a new MTX
product. The amount of proration is determined by dividing the original
purchase price by the number of months in the warranty period (60), then
multiplying the result by the number of months remaining in the warranty
