## What is Crank It for Denon & Marantz?

Crank It for Denon & Marantz allows you to control compatible Denon & Marantz receivers. Designed for maximum responsiveness, this app was made because sometimes you need to change the volume of your receiver really precisely, but also really FAST.

THIS APP IS OPEN-SOURCE: https://github.com/xaphod/CrankIt

This app can:
- change the volume (slide up/down anywhere on the screen, or use a preset)
- change the input source (ie. switch from DVD to TV)
- change the MultiEQ setting (ie. turn off Audyssey)
- toggle mute
- control zone 2 and main zone
- play/pause, skip prev/next, show album art -- requires HEOS-enabled receiver

This app supports only receivers made by Denon & Marantz that have an IP address, and are listening on port 23. In practice this translates to receivers made from roughly 2013 onwards.

Although this app has functionality designed to prevent you from accidentally turning your receiver up too loud, no software is perfect: by using this app you assume all responsibility for the volume levels & other functions set on your receiver, including those set by this app.

## Key features

- Precise volume control
- Input source switching
- MultiEQ setting adjustment
- Mute toggle
- Zone 2 and main zone control
- Playback controls (HEOS)

### 1/5 — Marantz SR7011

*2026-02-25*

Unfortunately, I am unable to connect through my WIFI either by selecting the Marantz SR7011 that it will find or by manually keying in its IP manually.  I get an error “Please try again
There was a problem issuing the command, please try again.”

### 5/5 — Works well

*2025-10-28*

Fast and efficient. My Denon AVR has been clunky and inconsistent. This is the complete opposite. Thanks for building this!

### 4/5 — App suddenly cannot find my Denon

*2024-08-27*

After years of working flawlessly, Crank It stopped finding and connecting to my Denon.  I have resorted to manually inputting the IP address to connect.  Any suggestions other than unplugging receiver (didn’t work) would be appreciated.  Love this app!

### 5/5 — Best quick volume remote for Denon audio in 2024

*2024-07-13, version 1.1*

Title says it all

It's free
Open source
No ads 
Works great 

Use it

### 1/5 — Multizone?

*2024-01-31, version 1.1*

App says it does multizone. Downloaded it. Doesn’t do multizone. Delete. 1 star.

### 5/5 — Just works

*2023-11-30, version 1.1*

Thank you dev (devs?). Denon needs to hire you

### 5/5 — Doesn’t connect using iPads

*2023-03-14*

Works using iPhone. On iPads, the app finds the Denon stereo but doesn’t connect on iOS 16.3.1 (iPad Pro). It used to work on iPad Air iOS 12.5.7, but not anymore. Doesn’t work inputting IP address either.

ISSUE RESOLVED: I needed to be on the same WiFi as the Denon Receiver for the iPads to connect to it.

### 3/5 — Worked, but no zone control

*2022-06-20*

Worked immediately and picked up my denon avr-s750, which the denon app could not!
But I was hoping for zone control so I could use it for controlling my outside speakers on zone 2.

### 5/5 — Denon should hire this guy to make their app

*2022-05-19*

Simple, and much more useful than the confusing, and unreliable Denon app. Once a receiver is setup, people want to change the source, and volume, quickly and reliably. This accomplishes that in a very intuitive and creative way. D&M should hire the developer to fix their failed remote control app. On top of that, I would have paid $5.00 for a good remote like this that works well, and the developer gives it away to the world, ad-free. Thank you sir!!! 

Now, a nice feature to add would be to have the ability to make a widget or Siri command that you can one click turn on the receiver and change to a specific input (Sonos Port users anyone?). Maybe a premium feature offering someday, or in-app purchase?? A guy can only hope so. Either way, great work!

### 5/5 — This app rocks

*2022-05-18*

Thanks so much for putting this together. Since Denon hasn’t updated their remote app supporting older receivers like my AVR-X3000, I’ve lost network control of it. What’s worse, while that app allows you to manually specify an IP address, it doesn’t work across VLANs. Even before I put the receiver on a separate VLAN, their app worked rather poorly with constantly forgetting the receiver and not being able to find it again without uninstalling and reinstalling.

This app works perfectly. It scanned my network and of course didn’t find the receiver because it’s on my IoT VLAN, but quickly prompted for an IP address which I provided. Immediately was able to power on and control my X3000.

Fantastic! Why Denon can’t seem to figure out how to make a decent and supported app is beyond me.
