GTR AMPLIFIERS
4. Remote (GTR-601, GTR-1001, GTR-7535):
Connect an 18awg wire from the “Remote Out” lead of the source unit to the REM input. This lead detects signal and instructs the amplifier to turn on.
(
See 12. REM
below for remote connection info for the
GTR-102
and
GTR-104
models.)

5. Front and rear inputs and outputs (RCA):
• If your source unit offers preamp outputs, connect to the FRONT, REAR, and/or SUB inputs using RCA patch cables.
• To connect a second amp directly to the amplifier, run a patch cable from the PRE OUT outputs to the second amp’s preamp inputs. (Available on
GTR-102
and
GTR-104
amplifiers only.)
6. Input level:
Select LO if providing signal to the amp using line-level connections. Select HI1 or HI2 if using speaker-level connections.
7. Crossover-filter selectors (GTR-102, GTR-104, GTR-7535)
Slider switches for selecting high-pass (HP), low-pass (LP), or FULL.
GTR-601
and
GTR-1001
filters are low pass only.
(See
Setting the Crossover
in Chapter 4.)
8. Gain:
Use input level controls to match the amp’s input sensitivity to the output level of your source unit. (See
Setting the input levels
in Chapter 4 for a
recommended adjustment procedure.)
9. Crossover Frequency Controls:
Use crossover-filter frequency controls for adjusting crossover point settings for full-range speakers and subwoofers.
(See
Setting the Crossover
in Chapter 4.)
10. ADAS Assign (GTR-102, GTR-104, GTR-7535):
When you connect your ADAS system to your GTR amp (cable sold separately), the amp will broadcast your vehicle’s driver assistance messages, such as
lane-departure warnings. By turning the ADAS Assign dial you can select the speaker the messages will be broadcast over. You can choose to hear messages
over your front left or FL (driver’s side), front right or FR (passenger side), rear left, or rear right speaker. Your music will mute when a warning or message is
broadcast, then resume when they’re finished.
11. Controller (GTR-102, GTR-104, GTR-7535):
Connect the supplied remote control panel to the amplifier’s Telephony connector, as shown in the illustration below. The remote control panel includes a long
cable and a mounting flange, allowing it to be mounted in a convenient location in the vehicle’s cabin.
